Q: Answer the following question given this paragraph: conditions. Esters are neutral compounds that undergo hydrolysis, a reaction with water. Under acidic conditions, hydrolysis is essentially the reverse of esterification. When carried out under basic conditions, the process is called saponification. Inorganic acids also react with alcohols to form esters. Some of the most important esters in biochemistry are those formed from phosphoric acid. Amines are nitrogen-containing organic molecules derived from ammonia (NH3). A primary (1) amine (RNH2) has one organic group bonded to the nitrogen atom, a secondary (2) amine (R2NH) has two organic groups bonded to the nitrogen atom, and a tertiary (3) amine (R3N) has three organic groups bonded to the nitrogen atom. Amines are basic compounds that react with strong acids to produce ammonium (NH4+) salts. A cyclic compound in which the ring contains one or more noncarbon atoms is called a heterocyclic compound. There are many heterocyclic amines, including many physiologically important ones. Alkaloids are heterocyclic amines found in many plants. Caffeine, nicotine, and cocaine are familiar alkaloids. Organic compounds containing a carbonyl group bonded to a nitrogen atom are amides, and the carbon-to-nitrogen bond is an amide linkage (or a peptide linkage). Most amides are colorless and odorless, and the lighter ones are soluble in water. Because they are polar molecules, amides have comparatively high boiling points and melting points. Amides are synthesized from carboxylic acids and NH3 or amines. Amides are neutral compounds. They resist hydrolysis in water, but acids, bases, and enzymes catalyze the reaction. Q: Esters are neutral compounds that undergo what process, which is a reaction with water? A:
Answer: hydrolysis

Problem:OPTIONS:
- dopamine
- insulin
- estrogen

Answer the following question given this paragraph: The gonads secrete sex hormones. The male gonads are called testes . They secrete the male sex hormone testosterone. The female gonads are called ovaries . They secrete the female sex hormone estrogen. Sex hormones are involved in the changes of puberty. They also control the production of gametes by the gonads. Q: The testes produce what hormone? A:
****
A: testosterone

OPTIONS:
- thermoregulation
- calcification
- enculturation
- osmoregulation
osmoregulation

Answer the following question given this paragraph: Resistance is the property that determines the amount of current flow through a particular material. Q: What is the property that determines the amount of current flow through a particular material? A:
OPTIONS:
- pressure
- surface tension
- demand
- resistance

Answer: resistance

Question: Answer the following question given this paragraph: After spermatids form, they move into the epididymis to mature into sperm, like the one shown in Figure below . The spermatids grow a tail and lose excess cytoplasm from the head. When a sperm is mature, the tail can rotate like a propeller, so the sperm can propel itself forward. Mitochondria in the connecting piece produce the energy (ATP) needed for movement. The head of the mature sperm consists mainly of the nucleus, which carries copies of the father's chromosomes. The part of the head called the acrosome produces enzymes that help the sperm head penetrate an egg. Q: After spermatids form, they move where to mature into sperm? A:
OPTIONS:
- into the prostate
- into the volaris
- into the vans deferens
- into the epididymis
Answer: into the epididymis

Sunspots are cooler, darker areas on the Sun's surface ( Figure below ). Sunspots occur in an 11-year cycle. The number of sunspots begins at a minimum. The number gradually increases to the maximum. Then the number returns to a minimum again. Q: What is the year cycle that sunspots occur? A:
A:
output:
