Q: Answer the following question given this paragraph: Evidence is a direct, physical observation of something or a process. Q: In a scientific investigation, what do you call a direct, physical observation of something or a process? A:

OPTIONS:
- sighting
- declaration
- reason
- evidence

A: evidence

input: OPTIONS:
- blue giant
- green giant
- white giant
- red giant Now, answer this question: Answer the following question given this paragraph: Eventually a main sequence star will use up all of its hydrogen. It then starts to fuse helium atoms into larger elements like carbon. At this time, the star's core will collapse inward. The star's outer layers will spread out and cool. The result is a larger star that is cooler on the surface, and red in color. The star is now a red giant . Q: When a star's core collapses inward while the outer layers spread and cool, what "colorful" celestial body forms? A:
A:
output: red giant

Q: Answer the following question given this paragraph: Ketones are carbonyls in which the carbon atom makes single bonds with two other carbon atoms. Ketones are less reactive than aldehydes and are a common component in nail polish removers and paint strippers. Q: What word describes a carbonyl where the carbon atom makes single bonds with two others? A:
Answer: ketones

Problem:OPTIONS:
- oils
- acids
- lipids
- proteins

Answer the following question given this paragraph: Geneticist Many diseases arise from genetic mutations that prevent the synthesis of critical proteins. One such disease is Lowe disease (also called oculocerebrorenal syndrome, because it affects the eyes, brain, and kidneys). In Lowe disease, there is a deficiency in an enzyme localized to the Golgi apparatus. Children with Lowe disease are born with cataracts, typically develop kidney disease after the first year of life, and may have impaired mental abilities. Lowe disease is a genetic disease caused by a mutation on the X chromosome. The X chromosome is one of the two human sex chromosome, as these chromosomes determine a person's sex. Females possess two X chromosomes while males possess one X and one Y chromosome. In females, the genes on only one of the two X chromosomes are expressed. Therefore, females who carry the Lowe disease gene on one of their X chromosomes have a 50/50 chance of having the disease. However, males only have one X chromosome and the genes on this chromosome are always expressed. Therefore, males will always have Lowe disease if their X chromosome carries the Lowe disease gene. The location of the mutated gene, as well as the locations of many other mutations that cause genetic diseases, has now been identified. Through prenatal testing, a woman can find out if the fetus she is carrying may be afflicted with one of several genetic diseases. Geneticists analyze the results of prenatal genetic tests and may counsel pregnant women on available options. They may also conduct genetic research that leads to new drugs or foods, or perform DNA analyses that are used in forensic investigations.

Answer the following question given this paragraph: Buffers work well only for limited amounts of added strong acid or base. Once either solute is all reacted, the solution is no longer a buffer, and rapid changes in pH may occur. We say that a buffer has a certain capacity. Buffers that have more solute dissolved in them to start with have larger capacities, as might be expected. Human blood has a buffering system to minimize extreme changes in pH. One buffer in blood is based on the presence of HCO3 and H2CO3 [H2CO3 is another way to write CO2(aq)]. With this buffer present, even if some stomach acid were to find its way directly into the bloodstream, the change in the pH of blood would be minimal. Inside many of the body's cells, there is a buffering system based on phosphate ions. Q: Human blood has a buffering system to minimize extreme changes in what? A:
****
A:
ph
