Cell plate was formed in plant cell during telophase.
Answer:
CO₂, also known as carbon dioxide
Explanation:
In the alveoli, oxygen enters the bloodstream, and carbon dioxide exits, the latter to be exhaled from the lungs.
Answer:
Phospholipid bilayer determinates which molecules can enter or exit the cell so its purpose is to be a checker in the middle. Cell membrane determinates the structure of the cell and it is the connection to the rest that happens in a cell.
Explanation:
Molecules can move in 2 ways: passive and active.
The only difference is the energy that is needed to do the movement.
In passive mechanisms, energy is not used, while in active transport, energy is needed. Diffusion or passive transport are moving the concentration from hight to low so the energy is not necessary. Active transport moves from low to a high concentration and it uses metabolic energy.
It represents the history of time which ends up being divided on the basis of the earth's biotic composition
