Why does water move through a membrane?
AnnZ [28]

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.

Answer:
1. Substitution
2. Insertion and deletion
3. Amino acids can have more than one codon that signals for it. Due to this, some substitutions don’t affect the protein at all.

Explanation:
1. Substitution sometimes isn’t as impactful. It can result in the same amino acid to be signaled as the original one since amino acids can have more than one codon signaling for it.
2. Insertion and deletion are also known as frameshift mutations. This is because they shift the codon spots by adding or deleting a nucleotide.
