Problem:OPTIONS:
- formaldehyde and cadaverine
- sulfur and formaldehyde
- methane and sulfur
- cadaverine and putrescine

Answer the following question given this paragraph: Neutral amines are weak bases, because the lone pair on nitrogen can act as a proton acceptor. Many smaller amines have very strong and offensive odors. For example, the aptly-named compounds cadaverine and putrescine are foul-smelling amines, formed as a part of the decay process after death. Q: What are the names of foul-smelling amines, formed as a part of the decay process after death? A:
****
A: cadaverine and putrescine

Answer the following question given this paragraph: Blood vessels help regulate body processes by either constricting (becoming narrower) or dilating (becoming wider). These actions occur in response to signals from the autonomic nervous system or the endocrine system. Constriction occurs when the muscular walls of blood vessels contract. This reduces the amount of blood that can flow through the vessels (see Figure below ). Dilation occurs when the walls relax. This increases blood flows through the vessels. Q: What structures of the cardiovascular system help regulate body processes by either constricting or dilating? A:
OPTIONS:
- muscles
- cartilage
- capillaries
- blood vessels
blood vessels

Answer the following question given this paragraph: Bottleneck effect occurs when a population suddenly gets much smaller. This might happen because of a natural disaster such as a forest fire. By chance, allele frequencies of the survivors may be different from those of the original population. Q: What effect occurs when a population suddenly gets much smaller, due to natural disaster or other cause? A:
OPTIONS:
- convergence effect
- limitation effect
- extinction effect
- bottleneck effect

Answer: bottleneck effect

Question: Answer the following question given this paragraph: Cancer can also be found in children. But childhood cancer is rare. Leukemia is the main type of cancer in children. It makes up about one third of all childhood cancers. It happens when the body makes abnormal white blood cells. Q: Production of abnormal white blood cells occurs in what cancer, which is the most common form in children? A:
OPTIONS:
- Brain
- Breast
- Bone
- leukemia
Answer: leukemia

input with options: Answer the following question given this paragraph: Bases are ionic compounds consisting of hydroxide ions and a cation. Naming and formula writing for bases follows the same guidelines as for other ionic compounds. Q: Bases are ionic compounds consisting of hydroxide ions and a what? A:
OPTIONS:
- cinion
- carbonate
- sulfate
- cation
output: cation

Problem: OPTIONS:
- weight
- diameter
- height
- density
Q: Answer the following question given this paragraph: As you know, density is defined as the mass per unit volume of a substance. Since gases all occupy the same volume on a per mole basis, the density of a particular gas is dependent on its molar mass. A gas with a small molar mass will have a lower density than a gas with a large molar mass. Gas densities are typically reported in g/L. Gas density can be calculated from molar mass and molar volume. Q: What is defined as the mass per unit volume of a substance? A:
Answer:
density
