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: 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 #2: Which of the following structures is present in both prokaryotic and eukaryotic cells

A. Chloroplast

B. Cell membrane

C. Golgi apparatus

D. Endoplasmic reticulum

Answer Explanation

Both prokaryotic and eukaryotic cells have a cell membrane. The cell membrane is a barrier that surrounds the cell and separates its internal environment from the external environment.
Q #3: Which of the following describes one difference between skeletal muscles and cardiac muscles?

A. Skeletal muscles are found in the viscera whereas cardiac muscles are found in the cranium

B. Cardiac muscles contain intercalated discs, whereas skeletal muscles do not

C. Cardiac muscles are voluntary, whereas skeletal muscles are involuntary

D. Skeletal muscles are autorhythmic, whereas cardiac muscles are not

Answer Explanation

Cardiac muscles have intercalated discs that enable them to contract in a coordinated manner. Skeletal muscles do not have intercalated discs, as their contraction is under voluntary control and does not require the same level of synchronization seen in the involuntary contraction of cardiac muscle.
