Answer:
Water can diffuse across a selectively permeable membrane in a process called osmosis. Osmosis in cells is a form of facilitated diffusion. ... But the cell membrane contains channel proteins that only water molecules can pass through. Osmosis allows cells to maintain water balance as their environment changes. it realates to hemeostasis Cellular homeostasis involves maintaining a balance of several factors that make a cell healthy. The cell membrane is a lipid bilayer that prevents the passage of water and ions. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell.
Explanation:
Monomer of nucleic acid is Nucleotide.
Nucleotide is made up of three components namely- Nitrogenous base, pentose suger and phosphate group.
Depending upon the nucleic acid,i.e RNA or DNA, nucleotide can be Ribonucleoside triphosphate (rNTP) and deoxyribonucleoside triphosphate repectively (dNTP).
Answer:
The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. Interphase is further subdivided into G1, S, and G2 phases. After the synthesis phase, the cell proceeds through the G2 phase.
