Answer;
The substance that can enter a cell by diffusion without having to be digested is water.
Explanation;
Diffusion involves the movement of molecules from a region of high concentration to a region of low concentration, down a concentration gradient.
Water is able to diffuse through the cell membrane without being digested since it has small molecules.
One property of cell membrane is semi-permeability; it selectively allows material to enter or leave the cell. Large molecules such as starch , fat and proteins, can not enter the cell due to their size and will need to be digested to small molecules for the to gain access to the cell.

it changes the composition of the DNADNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.
DNA is double stranded while RNA is single stranded.
DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.
Answer:
Rabbits are adapted to a certain type of environment and conditions, not certainly winter. So this effect the survival rate of the rabbits.
Moreover, their diet intake may be affected, for example, they are herbivores, so the plants they consume might not be present in this harsh season.
Then, competition with other animals increases as well, so the rabbits might have more predators.
