They move molecules against their gradient

Explanation:

Active transport is the process by which molecules are moved against their concentration gradient from a low concentration to a high concentration. This process requires energy.

The proteins associated with the plasma membrane are essential for this process. They use ATP to help molecules cross the cell membrane. They do not store ATP, and do not necessarily collect water molecules, but they do help to move molecules against their concentration gradient

this protocol describes a detailed procedure for intracellular flow cytometry staining.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
