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: Mars is the easiest planet to observe. As a result, it has been studied more than any other planet besides Earth. People can stand on Earth and observe the planet through a telescope. We have also sent many space probes to Mars. In April 2011, there were three scientific satellites in orbit around Mars. The rover, Opportunity, was still moving around on the surface. No humans have ever set foot on Mars. NASA and the European Space Agency have plans to send people to Mars. The goal is to do it sometime between 2030 and 2040. The expense and danger of these missions are phenomenal. Q: Which other planet in the solar system is the easiest to observe from earth? Choices: - Pluto - Mercury - Jupiter - mars A:
(Answer)
mars
Ques: Answer the following question given this paragraph: Thiols (also called mercaptans), which are sulfur analogs of alcohols, have the general formula RSH. Methanethiol (also called methyl mercaptan), has the formula CH3SH. Ethanethiol (ethyl mercaptan) is the most common odorant for liquid propane (LP) gas. The mild oxidation of thiols gives compounds called disulfides. Q: The mild oxidation of thiols gives compounds called what? Choices: - carbonates - halides - dioxides - disulfides A:
Ans: disulfides
(Q).
Answer the following question given this paragraph: Ore is extracted from rock by heap leaching, flotation, or smelting. Q: What is extracted from rock by heap leaching, flotation, or smelting? Choices: - methane - copper - fuel - ore A:
(A).
ore
Ques:Answer the following question given this paragraph: Benzene is the smallest aromatic hydrocarbon. It has just one ring. You can see its structural formula in Figure below . Benzene has many uses. For example, it is used in air fresheners and mothballs because of its strong scent. Q: What is the smallest aromatic hydrocarbon? Choices: - naphthalene - anthracene - phenanthrene - benzene A:

Ans:benzene
Ques: Answer the following question given this paragraph: An acidic solution and a basic solution react together in a neutralization reaction that also forms a salt. Q: What is formed when an acidic solution and a basic solution react together in a neutralization reaction? Choices: - Sodium - seawater - shallow - salt A:
Ans:
salt
