Answer:
It is called the "active site"
Explanation:
Answer:
I. Cell capsule
II. Cell wall
III. Plasma membrane
IV. Nucleoid
V. Cytoplasm
Explanation:
In the structure of bacterium, I represent Cell capsule which is the outer covering of bacterium cell, II is the Cell wall that is located after the cell capsule. III is the Plasma membrane which is also called cell membrane which is the second boundary of cell. IV represents Nucleoid which like nucleus having genetic material, V is Cytoplasm that is responsible for the transportation medium for various nutrients..
To answer your question: the nucleus has a membrane.
<span>Active transport is a process requiring energy in which a substance crosses the cell membrane. When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.</span>
