Sperm are the male reproductive cells. Most animals and plants use sperm to reproduce. They have different ways of making and releasing the sperm. In all cases the sperm meets with the egg of the female and together they grow into a new organism. The name sperm is taken from the Greek word "sperma" meaning "seed". An animal sperm cell is capable of movement, as it has to get to the uterus to meet with the ovum. Animal sperm cells (including humans) have small 'head' and a long tail called a "flagellum". The flagellum acts like a motor to propel the sperm cell through the female reproductive system.  In humans. Human sperm is made in the testicles of a man. Human sperm contains 23 chromosomes. A human needs 46 chromosomes, so a sperm cell is called a "haploid" as it only has half. The other half is contained within the ovum or egg of a female. During sex, semen is shot out of the man's penis during ejaculation. Semen carries the sperm into the woman's vagina and down to the ovum in the uterus. During ejaculation millions of sperm cells are released in the semen, but only one hundred or so reach the egg. The egg can merge with one sperm cell that reaches it. Because it now has 46 chromosomes, it is called a "diploid", like ordinary cells of the body. This diploid is called a zygote, and it can grow into a fetus and eventually a baby. In plants. Some plants such as ferns and mosses have sperm that move. Flowering plant sperm cells cannot move by themselves. The flowering plant sperm cells are contained within pollen grains. Thus, they rely on "transportation" to take their sperm cells to other plants. For example, a bee lands on a plant to collect the nectar. Some pollen will get stuck to the bee. The bee moves on to another plant and the pollen falls onto that plant. The sperm is moved down a "pollen tube" until it reaches the ovule at the bottom of the flower.
Semen () is the fluid that comes out from the urethra, at the end of a man's penis when he has an orgasm (the height of sexual excitement) and ejaculates. It is usually a white or yellowish, sticky substance made up of sperm (male cells for sexual reproduction) floating in a fluid called seminal plasma that has water and different chemicals in it. Normally, an ejaculation makes between 1.5 and 5 millilitres (up to one teaspoonful) of semen. Many cultures around the world once thought or still think that semen has special or even magical qualities. Showing semen in forms of popular culture such as art and movies has for a long time been taboo, that is, not generally accepted by society. However, since the late 20th century, artists and moviemakers have done so more often. Words. The English word "semen" comes from the Latin word "sēmen", which means "seed". In fact, "seed" was an old-fashioned name for semen. The Latin word "sēmen" itself came from another Latin word, "serěre", which means "to plant (a plant into the ground) or to sow (seeds in the earth)". It was once thought that semen was like a seed that grew into a baby after being "planted" inside a woman's body. Another name for semen is "ejaculate". Some slang words for semen are "cream", "cum", "jism", "jizz", "jazz" "load", "spooge", "spunk", "nut", or "wad". The way it looks and its nature. Semen is the fluid that comes out from the end of a man's penis when he has an orgasm (the height of sexual excitement) and ejaculates. It is usually white, but may also be slightly grey or yellow. If there is blood in the semen, it can look pink or reddish. This is a condition called hematospermia, and may be because of some blockage, inflammation, infection or injury to some part of the male sex organs, such as the urethra, epididymis, prostate
Bilbao () is a city in the Basque Country, in the North of Spain. There are 350,000 people living in Bilbao.  In Bilbao is the Nervión river, which ends in the Bay of Biscay. Bilbao has an oceanic climate ("Cfb" in the Köppen climate classification). Bilbao was an industrial city, but today it is a tourist city. There are many things to see in Bilbao:
In the United States, a middle school is a school between elementary school (grades 1-5, 1-7, 1-6, 1-4 or 1-8) and high school (grades 9-12 or 10-12). Depending on location, middle school contains grades 5-8, 6-8, 7-8, or 7-9. Middle school is also sometimes called an intermediate school, junior high school or just "junior high". The school day is often very different in elementary, middle, and high schools. Unlike elementary schools, where students often stay with one or two teachers for most of the school day, middle school is usually the first time in which students change teachers after each class of usually about one hour. Students often study 6 subjects. They will be taught by a different teacher for each subject. The change from a one teacher-all subjects way of teaching helps create more independence for the pupil. They no longer have the guidance of just one main teacher. Also, students will often have more of a choice in what classes they take. This is mainly in dealing with subjects which are taken in addition to the basic subjects such as mathematics, English, history and general science. In general, middle school acts as a transition between the elementary school structure where most people are all treated the same and the high school structure were most people are treated as individuals. However, some critics see middle schools as having gone "soft," overemphasizing self-esteem building at the expense of academic rigor. Historically, local public control (and private alternatives) have allowed for some variation in the organization of schools. Elementary school includes kindergarten through to sixth grade, or kindergarten through to fifth grade, i.e., up to age 12, but some elementary schools have four or eight grades, i.e., up to ages 10 or 14 (also known as the intermediate grades). Basic subjects are taught and pupils often remain in one or two classrooms throughout the school day, except for physical education, library, music, art, and computer classes. In 2001, there were about 3.6 million children in each grade in the United States.

The Ku Klux Klan is an American White supremacist hate group. It was started in Pulaski, Tennessee on December 24, 1865 and quickly expanded among White people in the southern United States.  Overview. Most of KKK's hatred is directed at African Americans, but it has also attacked Catholics, Jews and immigrants. Known as the KKK for short, it has sought to keep "white power", often through very violent acts, including killing people. The first Ku Klux Klan broke up and does not exist anymore. However, other groups with the same name and the same ideas have been created. Early years. The group was started after the American Civil War, in the time of the Reconstruction. It began as a social club for former Confederate soldiers, who during the war fought to defend slavery. The Klan quickly became a terrorist organization. When the KKK started, the ex-Confederacy states were occupied by soldiers from the north. Klan members feared white people in the South could lose their supremacy over black people. The Klan acted against black voters to intimidate them. At times, Republicans were also attacked by the Klan. The methods of acting against people were often the same: the Klan members tried to frighten the people that the Klan wanted to go out of town. The KKK tried to scare people by burning crosses or by threatening them. If people did not react, the Klan would kill them. The growing violence which was promoted by the KKK led to many lynchings (execution without a fair trial and killing them, often by hanging). The KKK was "prohibited" (made against the law) in 1871.  After 1871, many KKK members were imprisoned (put in prison). However, the Klan had achieved many of its original goals. For instance, the occupation troops were moved out of the Southern states, to the West. The KKK affected many African Americans throughout the last century. The establishment of Jim Crow laws restored white supremacy in the South and the "first era" KKK disbanded. The second Ku Klux Klan. In 1915, William J. Simmons, an Atlanta businessman, started the Ku Klux Klan for a
Brown v. Board of Education of Topeka, 347 U.S. 483 (1954) (full name George Brown, et al. v. Board of Education of Topeka, Kansas) was a Landmark decision by the Supreme Court of the United States. In 1950 in Topeka, Kansas, a black third-grade girl named Linda Carol Brown had to run more than a mile through a railroad switchyard to get to her segregated school for black children. However, there was an elementary school for white children less than seven blocks away. At that time, many schools in the United States were segregated. Black children and white children were not allowed to go to the same schools. Her father, Oliver Brown, tried to get Linda into the white school, but the principal of the school refused. Twelve more black parents joined Oliver Brown in trying to get their children into the white elementary school. The two schools were supposed to be "separate but equal." However, they were not. In 1951, the National Association for the Advancement of Colored People (NAACP) helped the parents file a class action lawsuit. There were five lawsuits in Kansas, South Carolina, Virginia, Delaware, and the District of Columbia about having black students going to legally segregated schools. In 1896, the Supreme Court had ruled in "Plessy v. Ferguson" that segregation was legal, as long as separate places for blacks and whites were "separate but equal." The NAACP's lawyers argued that the white and black schools in Topeka were not "separate but equal." Kenneth Clark is a psychologist that gave young African-American children black and white dolls to see how they felt about segregation and integration. The children liked the white dolls. After the doll test, Clark also gave the black children drawings of a kid and asked them to color it like themselves. Some of the children colored themselves with a white or yellow crayon, which was also used in the case. The case eventually went all the way to the Supreme Court. After years of work, in 1954, Thurgood Marshall and a team of other NAACP lawyers won the case. It was named "Brown"
A well is a hole that is dug into the Earth to get a fluid. Most wells are to get water. There are also oil well s and gas wells.  Wells can be as simple as a hole that a bucket on a rope can be lowered into, or very complex with pipes and high-powered pumps to get the water out. Most cities that are not close to fresh water lakes or rivers get their water from wells.  It is important to be careful what rubbish is put into the ground near a well. If something toxic is put in the ground, it could go in the groundwater and the well and make people sick. A qanat is an ancient complex water well system used in the Middle East. Water is a problem for many African countries. Many charities are helping to build wells in local villages so people need not go far to get water. A well only works if underneath there is a source of water, such as an aquifer, which feeds it.
Honey is a food made by honeybees from nectar. They put the honey into a honeycomb, which for them is a storage unit. Honey is sweet and can be used instead of sugar. It is a supersaturated liquid. As the temperature drops, glucose comes out of solution. Then it is a semi-solid rather than a liquid. Honey is first mentioned in the Book of Exodus, and is often linked with pleasant and comfortable things. "Land of Milk and honey". It is also referenced in the Qur'an, with similar associations to good and evil. The name honey is derived from the Old English ". Much like wine, there are several kinds of honey with different tastes, colors and textures. Some common types are got from bees who use the clover flower's pollen. It is thick and has a medium color. It tends to form crystals or grains more quickly when exposed to air. Acacia flowers make another common variety. Honey from bees using flowers from oleanders, rhododendrons, some laurels, and azaleas may cause honey intoxication. Symptoms include dizziness, weakness, sweating, nausea, and vomiting.  Expert beekeepers solve this problem by moving their hives to areas where the right flowers are available. Bees like to get their nectar locally, and do not go more than two miles from the hive. Honey tastes quite different according to which flowers the bees used. Key things are its smell, taste and how clear it is; also no bad qualities. Most microorganisms cannot grow in honey and a honey that's packed therefore does not get spoiled. Samples of honey discovered in archaeological contexts in Egypt and some other countries have proven that honey is perfectly edible even after thousands of years. Some of the worlds oldest jars of honey have been found in ancient egyptian tombs. Classification. Source of flower. Honey can be classified by the type of flower that the bees make the honey from. Blended. Most commercially available honey is a mixture of two or more honeys that differ in the source of the flower, color, flavor, density, or geographic origin. Polyfloral. Polyfloral honey, also called wildflower honey, is gotten from the n
A cracker is a thin and crispy piece of baked bread. Crackers can be eaten by themselves, but they can also be eaten with things on them called toppings. Common toppings include cheese, peanut butter, and sliced meats. Crackers are most often eaten as a snack, or crumbled into soup. History. In 1792, Theodore Pearson of Newburyport, Massachusetts, made a cracker-like bread that was made from only water and flour which he called "Pearson's Pilot Bread." This was the first cracker bakery in the United States, and made crackers for more than a century.
Surgery is an operation that involves cutting, taking out, changing or fixing parts of the human body. Doctors who do surgeries are called surgeons. Many surgeons are experts in certain areas; for example brain or heart or eye surgery. One who operates on bones is an orthopaedic surgeon. Surgery (operations) can be simple, like taking a tooth out. Surgery can also be complicated, like repairing a damaged heart. Operating rooms have to be very clean places. The doctors and nurses go to great lengths to keep the room clean where the surgery is done. Regular cleaning of the room and its tools keeps everything clean and germ-free. Everyone in the operating room must wear special clothes, hats, shoes, gowns, gloves and masks that are clean and germ free. The only people allowed there are the doctors and nurses as well as the patient. When people have operations they are normally put to sleep with general anaesthesia. When the patients are asleep, they cannot feel anything. In some kinds of surgery local anesthesia (stopping the pain in the place where the cutting is done) is enough. In recent years, many patients that cannot get the required surgery in their own country, or find the costs too high, travel to another country for medical care. This is called medical tourism.
Pizza is an Italian food that was created in the Naples area, Southern Italy. It is made with different toppings. Some of the most common toppings are mozzarella (a kind of cheese), sausages, pepperoni, vegetables, tomatoes, spices and herbs and basil. These toppings are added over a piece of bread covered with sauce. The sauce is most often tomato-based, but butter-based sauces are used, too. The piece of bread is usually called a "pizza crust". Almost any kind of topping can be put over a pizza. The toppings used are different in different parts of the world. Pizza comes from Italy, from Neapolitan cuisine. However, it has become popular in many parts of the world. History. The origin of the word "Pizza" is uncertain. The food was invented in Naples about 200 years ago. It is the name for a special type of flatbread, made with special dough. The pizza enjoyed a second birth as it was taken to the United States in the late 19th century. Flatbreads, like the focaccia from Liguria, have been known for a very long time. Pizzas need to be baked at temperatures of 200250 °C. Hardly any household oven could reach such temperatures at the time. Because of this, the pizza was made at home, and then given to the town bakery to bake. In June 1889, the Neapolitan chef Raffaele Esposito created the "Margherita" in honour of Queen Margherita, and was the first pizza to include cheese.  Pizza was brought to the United States with Italian immigrants in the late nineteenth century; and first appeared in areas where Italian immigrants concentrated. The country's first pizzeria (place that focuses in pizza), Lombardi's, opened in 1905. Veterans returning from World War II's Italian Campaign were a ready market for pizza. Since then, pizza consumption has increased in the U.S. Pizza chains such as Domino's, Pizza Hut, and Papa John's, have outlets all over the nation. Thirteen percent of the U.S. population eats pizza on any given day.  Types. In the 20th century
Heaven is a concept of the afterlife (what happens after somebody dies) in many religions. Some people who believe in heaven say that it is a place that is perfect. They believe heaven is where people will go after they die if they have been good. Some people also believe in Hell, which is a place where people will go when they die, if they have been bad. They believe hell is a punishment for being bad. Ideas of Heaven and Hell are not the same in all religions. In Christianity. According to the Bible, there are different meanings for the word: The Bible does not have a lot to say about what it looks like. The apostle Paul tells about a vision he had of being taken up to "the third heaven," where he saw and heard things too wonderful to describe. But, much of what Christians believe Heaven to be like comes from the vision that John saw in a vision while praying, including: Catholics believe Mary is the Queen of Heaven, officially defined by Pope Pius XII in 1954. However many Protestants see this as not in the Bible. In Islam. According to the Quran and Hadith, Heaven is a place of reward for those believers who accept the true faith and practices the teaching of Prophet Muhammad. The eternal life will be perfect, with thousands of types of food and clothing more beautiful than humans could ever imagine. There will also be no sad feelings, stress or pain and related problems of life. In Bahá'í Faith. Baha'is believe that Heaven or (hell) being specific places as symbolic. The Aqdas, the holy book of Baha'is, along with other Baha'i books, describe heaven as a "spiritual condition" where being close to God is called heaven. Hell is seen as being separated from God. Bahá'u'lláh, the founder of the Bahá'í Faith, said that the afterlife is beyond human understanding. In Paganism. Summerland is the name given by Wiccans and other Pagan (old European religions) to their belief of afterlife (life after death).
Multitasking means that a computer can run more than one item of software in the same time frame; switching between several computer programs running on a single CPU. It can also refer to a person who is working on more than one task at the same time (for instance, talking on the telephone while filing papers). In computing. Computers which can appear to run more than one program even with only one CPU. Computer scientists solve the problem that a CPU can only do one thing at a time by programming it so that it switches rapidly between tasks. This happens so rapidly that it appears that the computer is running more than one program at once. This is called "multiprogramming". This action is often controlled by the operating system (OS) controlling the hardware of the system. The more things the computer has to do at once, the more time it has to spend deciding which to give more time to, and the less time each one receives. This tends to make the computer perform its tasks more slowly, unless it uses a multi-core processor, acting as multiple CPUs, which is called "multiprocessing".
Fertilization (British English spelling: fertilisation) is when a male's sperm enters a female's ovum (or "egg"). Fertilization is also called "conception". Biologists call a fertilized egg a zygote. A zygote grows into an embryo. Fertilization occurs in animals, including humans and birds, in plants, fungi, protists, in fact all eukaryotes. Fertilization makes a cell with twice as many chromosomes. The eukaryote life cycle includes meiosis which divides the chromosome number in half. In animals. In animals, there are two types of fertilization, internal and external. Internal fertilization happens in the female body. External fertilization happens outside of the body. Mammals, birds, and reptiles use internal fertilization. Amphibians and most fish use external fertilization. Some animals with internal fertilization give birth to live offspring. Others such as birds, most reptiles, and some mammals such as the Platypus, lay eggs. Internal fertilization happens during mating (sexual intercourse in humans). Sperm cells travel from the male testicles to the female uterus. One sperm attaches to the egg in the uterus. Together, they become a zygote.
A chemist is a scientist who studies chemistry. In England, it can also mean a pharmacist (person who dispenses prescription medication).  Chemistry is the study of elements, atoms, molecules, and how they react together. Chemists research and test medicines, fuels, foods, explosives, household chemicals, plastics, and a lot of other things. Chemistry is an important science. It helps industry and pharmacology. Chemists are people who study compounds and find new ways to do chemical reactions. They make chemicals in order to find new ways to do things, like to make a better glue, or to make new medicines, or to make things clean, for example. They also use compounds to find out more about the laws of chemistry.
