(Question)
Read the following article and select the best answer. Article: DNA is a substance that makes up genes. Everything alive has genes. Plants have genes. Animals have genes. You have genes. Genes are the basic units of heredity . Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father. Genes are a kind of code. A tree's genes tell what shape its leaves will be. A cat's genes tell what color1 its fur will be. Your genes tell what color1 your eyes will be. Your genes tell what color1 your hair will be. Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells. An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits , Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were called genes. In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases--diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by _ genes through a process called gene therapy. Question: Which is the correct from large to small? - genes---chromosomes---cells - cells---chromosomes---genes - chromosomes---cells---genes - cells---genes---chromosomes
(Answer)
cells---chromosomes---genes

Ques: Read the following article and select the best answer. Article: The Lionfish Invasion! Lionfish are popular saltwater aquarium fish all over the world, especially in the United States. Nowadays, they also live in Atlantic waters off the East Coast of the United States. These lionfish are what scientists call an invasive species or an "alien invader." Local divers off the coast of North Carolina were not expecting to see what they found one day in August 2002--the beautiful lionfish, common to the warm waters of the western Pacific, but unknown of the Carolina coast. They provided the first solid evidence that lionfish were in the Atlantic. A year later, scientists documented 19 lionfish sightings at eight locations along the North Carolina continental shelf. Then, lionfish were observed off the coasts of Florida, Georgia, and South Carolina, and even as far north as Long Island, New York! Between 2000 and 2003, lionfish sightings were reported at 16 different shipwrecks and natural hard bottom locations. During a summer 2004 research expedition, NOAA(The National Oceanic and Atmospheric Administration) scientists collected 155 lionfish at 19 different locations off the North Carolina coast alone. The jump in numbers and distributions over such a short time strongly indicates that the lionfish is reproducing in the Atlantic Ocean. If this is true, it's the first time that a western Pacific fish has populated the U.S. Atlantic coast. These lionfish were likely released on purpose when people no longer wanted them! The swift and warm Gulf Stream, which transported the floating lionfish eggs from Florida northward, helped the lionfish's Atlantic journey. In Florida waters and along the continental shelf near the Gulf Stream the temperatures are very similar to the lionfish's native waters. However, from north Florida upward, the waters along the coastline are too cold in the winter for lionfish to survive. Scientists expect them to survive the winter only at water depths greater than 120ft because this is where the Gulf Stream has influence all year long. Very... Question: Scientists call the lionfish an "alien invader" because the lionfish _ . - have damaged the native species - are able to live in a new environment - came from one place and spread to another - will attack other species with their poisonous teeth
Ans: came from one place and spread to another

Ques: Read the following article and select the best answer. Article: "TODAY is a dream comes true. I have always wanted to be a Grand Slam champion." These are the words of Chinese tennis player Li Na after she became the first Asian woman to win a Grand Slam final in the French Open on June 4. "People were saying I'm getting old. So this is a great success for such an old woman," the 29-year-old joked. This is the way that Li usually fights doubts- by being humorous and sharp. "China's number one sister" is never a pushover . She has a tattoo . She has dyed her hair many different colors. And, at the 2008 Beijing Olympics, she told her fans to "shut up" when they got too noisy in their support. Li started to play tennis at the age of 6. She once recalled: "As a child, I felt sad because every day I had to wake up early to practice. After school I had to practice more. I didn't have time to play." Luckily, the tough girl didn't give up, thus making history for Chinese tennis time after time. Now the new champion is already thinking about winning another Grand Slam title. Her next stop is Wimbledon - the European grass court championship that starts later this month. "When you have one title, naturally you will think about another," she says, not hiding her ambition. "Chinese people are so lacking in confidence on the tennis court. If there is a person like me who can prove we can do it, the other young players in China will feel the same," she said. Question: From the passage, we know Li Na is _ . - outgoing - fashionable - tough - All above
Ans:
All above
