Answer the following question given this paragraph: Human skin color is primarily due to the presence of the pigment melanin in the skin. Melanin is not a protein, but it is the product of a biosynthetic pathway. Skin color is a polygenic trait and obviously demonstrates quantitative characteristics. A number of genes factor into determining a person's natural skin color, so modifying only one of those genes changes the color only slightly. It is currently thought that at least three separately inherited genes contribute to skin pigmentation. Let's call these three genes A, B, and C. A, B, and C are incompletely dominant to a, b, and c, with A, B, and C each contributing a "unit of darkness" to the phenotype. Therefore an AABBCC individual is very dark, darker than an AaBbCc individual, and much darker than a aabbcc individual. A person may have as many as 6 "dark units" to as few as no "dark units," and any combination in between. This will result in a phenotypic spectrum of color gradation. When graphed, a phenotypic spectrum usually results in a bell-shaped curve, with extreme phenotypes on both ends and more common phenotypes in the center of the curve. Q: Human skin color is primarily due to the presence of what pigment in the skin? A:
****
A: melanin

Question: Answer the following question given this paragraph: Homeostatic Process The goal of homeostasis is the maintenance of equilibrium around a point or value called a set point. While there are normal fluctuations from the set point, the body's systems will usually attempt to go back to this point. A change in the internal or external environment is called a stimulus and is detected by a receptor; the response of the system is to adjust the deviation parameter toward the set point. For instance, if the body becomes too warm, adjustments are made to cool the animal. If the blood's glucose rises after a meal, adjustments are made to lower the blood glucose level by getting the nutrient into tissues that need it or to store it for later use. Q: The goal of homeostasis is the maintenance of what, around a point or value called a set point? A:
OPTIONS:
- agitation
- steadiness
- imbalance
- equilibrium
Answer: equilibrium

input with options: Answer the following question given this paragraph: Condensation reactions are the chemical processes by which large organic compounds are synthesized from their monomeric units. Hydrolysis reactions are the reverse process. During condensation reactions, water is produced from the two molecules being bonded together; an H from one monomer is joined to an -OH from another molecule, producing H 2 O. Q: What is produced during a condensation reaction? A:
OPTIONS:
- rain
- wind
- fire
- water
output: water

Problem: OPTIONS:
- metabolytes
- chlorophyll
- hydrogen
- energy
Q: Answer the following question given this paragraph: After citric acid forms, it goes through a series of reactions that release energy. The energy is captured in molecules of NADH, ATP, and FADH 2 , another energy-carrying compound. Carbon dioxide is also released as a waste product of these reactions. Q: After citric acid forms, it goes through a series of reactions that release what, which is then captured in special molecules? A:
Answer:
energy
