Ions are transported across membranes using which requires ions are transported across membranes using which requires simple diffusion; kinetic energy channel-mediated facilitated diffusion; atp energy channel-mediated facilitated diffusion; kinetic energy carrier-mediated facilitated diffusion; atp energy

The correct answer will be options

1.  ATP energy channel-mediated facilitated diffusion

2.  ATP energy

Explanation:

The ions are transported across a biological membrane using ion transporters. These ion transporters are the transmembrane enzymes which use energy from ATP molecules to transport ions against a concentration gradient.

The ATP using channels converts the ATP energy to potential energy stored in the form of electrochemical gradient which is used to drive the process of formation of the ATP using ATP synthase.

Thus, the selected option is the correct answer.

amber has allowed scientists to study dna that has been preserved over millions of years.

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.
