Answer: Plasma membrane is flexible because it regulate gases and water from inside and outside the cell and it have to perform endocytosis and exocytosisin in which large particle of food and water get inside the cell and come out from the cell.

Answer:
12) When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution
16) In other words, plasma membranes are selectively permeable—they allow some substances through but not others. ... The most direct forms of membrane transport are passive. Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement.
19) To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.
If organisms can not adapt they become extinct.
Answer:
Like the nervous system, the endocrine system is a regulatory system. However, instead of using electrical impulses for signaling, it produces and uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.
