Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are <u>more abundant</u> in the <u>anterior portion</u> of the annelid´s body, in general, they are arranged in all the segments.

Annelids, such as the earthworm, have a variety of sensory cells:

  • <u>Photoreceptors</u>: Light-sensitive cells. Although they are <em><u>located in the whole </u></em>body, they are <em><u>abundant in anterior and posterior segments</u></em>, concentrated in the intern and dorsal part of the epidermis.
  • <u>Humidity receptors</u> are the most sensitive cells and are <u>located in the first segments</u> of the earthworm body

Answer:

B. Mitochondria

Explanation:

  • Mitochondria are known as the power house of the cell. They are the sites of cellular respiration that breaks down glucose into energy molecules such as ATP and energy storage molecules such as NADH and FADH2.
  • In this scenario, since the cell's energy levels fall and metabolism ceases, the organelle most likely affected is the mitochondria.
  • If mitochondria are affected, glucose will not be metabolized to ATP and the cell will not have sufficient energy for cellular functions.
