Nerve Conduction

Question 7 • Biology - SC3209 IC

Which best describes neurons?

Answer

Like all eukaryotic cells, neurons do not have the ability to regulate what substances go in and out of the cell.

Like all eukaryotic cells, neurons have a nucleus that controls the activities of the cell.

Unlike other eukaryotic cells, neurons cannot produce energy that can be used to carry out the life-sustaining processes of the cell.

Unlike other eukaryotic cells, neurons have a membrane that surrounds the cell.

Explanation

Neurons are eukaryotic cells, so they have a nucleus that contains genetic material and helps control the cell’s activities. Their cell membrane regulates what enters and leaves, so A is incorrect. Neurons also produce usable energy and are surrounded by a membrane, so C and D are incorrect.
