Answer:
The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.
Explanation:
The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water. In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.
A because water is collected in clouds from bodies of water than falls back down as rain snow or hail
Answer:
"Interphase was formerly called "the resting phase,"
Explanation:
The cell in 'interphase' is not rather "resting" but preparing for later cell division.
Answer:urbanization is responsible for the loss of vegetation and soils.
Explanation:
As urbanization alters the natural amount of water that takes each route.
They must occur in the DNA, which is in each cells nucleus. More specifically the nucleolus of the cell. A mutation occurs in an allele, where a base triplet (or a codon) gets transcribed incorrectly.
