Can someone please answer these for me? i’ll give brainlist Is energy required for substances to pass in or
out of the cell?

Which of the methods of transport into or out of
the cell require energy?

Which do not?
What's the function of the cell membrane?

energy can be needed for both passing in the cell or out of the cell, it depends on the type of transport. there is active transport and passive transport. passive transport does not require energy while active transport does. the function of the cell membrane is to act as a gateway for materials to go in and out and to choose what goes in and what doesn't and what leaves and what doesn't.

Explanation:

i took this chapter last week.

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.

what is this saying?
