Answer the following question given this paragraph: In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern. In a human karyotype, autosomes or "body chromosomes" (all of the nonsex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22). The X and Y chromosomes are not autosomes. However, chromosome 21 is actually shorter than chromosome 22. This was discovered after the naming of Down syndrome as trisomy 21, reflecting how this disease results from possessing one extra chromosome 21 (three total). Not wanting to change the name of this important disease, chromosome 21 retained its numbering, despite describing the shortest set of chromosomes. The chromosome "arms" projecting from either end of the centromere may be designated as short or long, depending on their relative lengths. The short arm is abbreviated p (for "petite"), whereas the long arm is abbreviated q (because it follows "p" alphabetically). Each arm is further subdivided and denoted by a number. Using this naming system, locations on chromosomes can be described consistently in the scientific literature. Q: What is another term for body chromosomes? Choices: - subsets - Chromosomes - quasars - autosomes A:
autosomes
Answer the following question given this paragraph: Cutting down on the use of chemical fertilizers is one way to prevent dead zones in bodies of water. Preserving wetlands is also important. Wetlands are habitats such as swamps, marshes, and bogs where the ground is soggy or covered with water much of the year. Wetlands slow down and filter runoff before it reaches bodies of water. Wetlands also provide breeding grounds for many different species of organisms. Q: Cutting down on the use of chemical fertilizers and preserving wetlands are ways to prevent what "unlivable" regions in bodies of water? Choices: - inhabitable zones - hostile zones - fresh zones - dead zones A:
dead zones
Q: Answer the following question given this paragraph: Q: What type of tissue transmits nerve impulses throughout the body? Choices: - connective - fibrous - epithelial - nervous A:
A: nervous
Question: Answer the following question given this paragraph: Q: What triggers the fight-or-flight response? Choices: - respiration - amphetamine - endorphine - epinephrine A:
Answer: epinephrine

Answer the following question given this paragraph: The cut on your hand may become red, warm, and swollen. These are signs of an inflammatory response. This is the first reaction of the body to tissue damage or infection. As explained in Figure below , the response is triggered by chemicals called cytokines and histamines , which are released when tissue is injured or infected. The chemicals communicate with other cells and coordinate the inflammatory response. You can see an animation of the inflammatory response at this link: http://www. sumanasinc. com/webcontent/animations/content/inflammatory. html . Q: The first reaction of the body to tissue damage or infection is called the what response? Choices: - defensive - harmful - retaliatory - inflammatory A:
**Answer**
inflammatory
(Q).
Answer the following question given this paragraph: Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH 2 , which result from the Krebs cycle, is transferred to ATP. Can you predict how this happens? ( Hint: How does electron transport occur in photosynthesis?). Q: What is the final stage of aerobic respiration, when energy from the krebs cycle is transferred to atp? Choices: - glycolysis - acetyl-CoA - cytoplasm transport - electron transport A:
(A).
electron transport
