Q: Joe studied the lives of humans. He studied 2 groups of people. Group G had people over 65 in it, and group Y had people under 65 years old in it. Which group had fewer people that were retired from work? Hint: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common.
A: group Y

Question: Two brothers were born 20 years apart. Tom, the older brother, was 72, while Dan was 52 years-old. they got along pretty well. Which brother didn't experience an increase in reflex time? Hint: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn't work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer's disease.
Answer: Dan

[Q]: After working out in the yard for the day doing various chores, Karen comes back inside to prepare for a shower. While waiting for the shower to heat up, she notices she got one cut on each of her arms. The cut on her left arm is hardly even noticeable, but the one on her right arm is red and easy to see. Karen gets some cream from her cabinet to use on her cuts after she gets done showering. Will the cut on Karen's right arm be warmer or cooler than the cut on her left arm? Hint: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue.

input: Please answer the following: Dan and Joe studied animals for biology class. Joe had to study predator animals, while Dan studied herbivores and grazers. Which student learned more about deer? Hint: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species.

Please answer this: Birch town was located 20 miles away from Free town. Birch town's population was affected by viral respiratory diseases, while Free town's population caught bacterial respiratory diseases. Which town has fewer people that caught the common cold? Hint: Many respiratory diseases are caused by pathogens. A pathogen is an organism that causes disease in another organism. Certain bacteria, viruses, and fungi are pathogens of the respiratory system. The common cold and flu are caused by viruses. The influenza virus that causes the flu is pictured below ( Figure below ). Tuberculosis, whooping cough, and acute bronchitis are caused by bacteria. The pathogens that cause colds, flu, and TB can be passed from person to person by coughing, sneezing, and spitting. Illnesses caused by bacteria can be treated with antibiotics. Those caused by viruses cannot.

Question: Two space explorers are flying around through an unknown galaxy when they discover two new planets. Given that these planets have no names, the explorers decide to name them after themselves. The planet of Sarahn is currently going through a large geographic shift. Many of the continents on the planet are currently breaking apart and moving. Timon, however, has been a stable planet with no continental moving for quite awhile now. Are the volcanoes on Timon more or less active than on Sarahn? Hint: At the end of the Proterozoic, the supercontinent Pannotia had broken apart into the smaller continents Laurentia, Baltica, Siberia and Gondwana. During periods when continents move apart, more oceanic crust is formed by volcanic activity. Because young volcanic crust is relatively hotter and less dense than old oceanic crust, the ocean floors rise during such periods. This causes the sea level to rise. Therefore, in the first half of the Paleozoic, large areas of the continents were below sea level.Early Paleozoic climates were warmer than today, but the end of the Ordovician saw a short ice age during which glaciers covered the south pole, where the huge continent Gondwana was situated. Traces of glaciation from this period are only found on former Gondwana. During the Late Ordovician ice age, a few mass extinctions took place, in which many brachiopods, trilobites, Bryozoa and corals disappeared. These marine species could probably not contend with the decreasing temperature of the sea water.The continents Laurentia and Baltica collided between 450 and 400 Ma, during the Caledonian Orogeny, to form Laurussia (also known as Euramerica). Traces of the mountain belt this collision caused can be found in Scandinavia, Scotland, and the northern Appalachians. In the Devonian period (416359 Ma) Gondwana and Siberia began to move towards Laurussia. The collision of Siberia with Laurussia caused the Uralian Orogeny, the collision of Gondwana with Laurussia is called the Variscan or Hercynian Orogeny in Europe or the Alleghenian Orogeny in North America. The latter phase took place during the Carboniferous period (359299 Ma) and resulted in the formation of the last supercontinent, Pangaea.By 180 Ma, Pangaea broke up into Laurasia and Gondwana.
