Accepted Answer

carbon dioxide

Answer

dissolved nitrogen

Answer

an enzyme

Answer

a hormone

Question 17

Which model identifies the process that converts light energy into chemical energy inside of a plant (like kelp for example)?

Accepted Answer

Question 18

Which statement uses the model to describe how kelp contributes to a reduction of carbon entering the atmosphere?

Accepted Answer

Some of the carbon stored in the dead kelp is trapped in the geosphere of the sea floor.

Answer

Kelp produces carbon as it grows within the hydrosphere.

Answer

Kelp produces carbon as it sinks into the hydrosphere.

Answer

Some of the carbon stored in kelp is added to the geosphere through cell respiration.

Question 19

Which statement provides the best explanation for how red blood cells contribute to a feedback mechanism that maintains homeostasis?

Accepted Answer

The aquaporins in the red blood cells facilitate the exchange of water in environments of different concentrations and help the kidneys more efficiently regulate salt and water balance.

Answer

The aquaporins in the red blood cells prevent the exchange of water in environments of different concentrations and help the kidneys more efficiently regulate salt and water balance.

Answer

The red blood cells change their shape to move through the kidney but have minimal effect on salt and water balance in the kidneys.

Answer

The red blood cells change their shape to move through the kidney but do not regulate any feedback mechanisms.

Question 20

Plants that yaks eat grow under stressful conditions. Decreased atmospheric pressure results in changes in the concentrations of gases, as represented below. Which statement best explains why the carrying capacity for producers in extreme-altitude ecosystems is less than in sea-level ecosystems?

Accepted Answer

There is less carbon dioxide available to use for photosynthesis at extreme altitudes.

Answer

There is more oxygen available to use for cellular respiration at high altitudes.

Answer

There is increased water vapor available at extreme altitudes which limits the process of photosynthesis.
