Which of the following characteristics of water helps explain why coastal areas experience less dramatic temperature changes during the day?

A. Water has a high specific heat capacity

B. Water is a versatile solvent

C. Water forms covalent bonds with other water molecules

D. Water's adhesive properties prevent evaporation

Answer Explanation:

Water has a high specific heat capacity, which means it can absorb and store a large amount of heat energy without significantly changing in temperature. This helps moderate the temperature fluctuations of the air near the coast, as water can store heat during the day and release it at night, or vice versa.

Therefore, the Correct Answer is A.

Q #1: Parasitic worm infestation is hypothesized to be damaging to the host. However, scientists have recently discovered that worm infestation can relieve the effects of certain autoimmune disorders, in which of the following ways should the hypothesis be modified, given the new findings?

A. Lack of worm infestations is the cause of some autoimmune disorders.

B. Worm infestation reduces the severity of certain autoimmune disorders

C. Worm infestation prevents the body from immune malfunction

D. Worm infestations exacerbate the body's immune reactions

Answer Explanation

The new findings can be used to generate a hypothesis to reflect the beneficial aspect of worm infestations in certain autoimmune disorders, indicating that they can help reduce the severity of the condition.
Q #2: Which of the following demonstrates a chemical reaction of water?

A. Water boils to produce steam at 100° C (252)

B. Water Dissolves sugar

C. Water produces gas with sodium metal

D. Water and all separate when combined

Answer Explanation

a. Water boils to produce steam at 100°C - This is a phase change (from liquid to gas) and not a chemical reaction of water.

b. Water dissolves sugar - This is a physical change, not a chemical reaction of water.

c. Water produces gas with sodium metal - This reaction involves the chemical reaction of water with sodium metal to produce hydrogen gas.

d. Water and oil separate when combined - This is a physical separation, not a chemical reaction of water.
Q #3: Which of the following substances is excreted by sweat glands in response to the breakdown of proteins and the formation of ammonia?
