Answer:

D. Fatty Acids

Explanation:

When fatty acids undergo beta-oxidation to serve as a source of ATPs, ketone bodies are produced. During starvation or medical conditions such as diabetes mellitus, carbohydrate supply to liver cells is depleted.

Once the stored glycogen has been depleted from the liver cells, the fatty acids are funneled into beta-oxidation to produce ATPs. The process also forms acetone,  acetoacetate, and D-beta-hydroxybutyrate, that is the ketone bodies. The more the fatty acid molecules enter the beta oxidation, the more ketone bodies are produced.

A. Air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

Explanation:

The most likely observation the student will record is that the air over the lake will reach its highest temperature later in the day and will stay warm longer than air over the ground.

This phenomenon between the differences in land and water temperature causes land sea breeze to occur.

  • Water has a very high specific heat capacity.
  • This implies it takes more heat to cause a monumental increase in its temperature.
  • It is expected that the student will observe that the air over the lake body will reach its highest temperature later in the day. It would have gotten heated with time.

A body such as water in a lake with a high specific heat capacity stays warm for a longer period of time compared to other substances.

Metals do not have high specific heat capacity and would not stay warm for long. They quickly lose heat.

How do cohesion and adhesion help water move up a plant
Ganezh [65]

Cohesion: When water molecules stick to one another through cohesion, they fill the column in the xylem and act as a huge single molecule of water (like water in a straw). Capillary action: Capillary action is the movement of a liquid across the surface of a solid caused by adhesion between the two.
