Which of these processes does not require the cell to use energy A cell division b protein synthesis c DNA replication D diffusi
weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

The phenotype is just a characteristic/trait. 

For instance Brown and Green are phenotypes of eye color. 

This can also be used in Punnet Squares, and could be displayed as B and G. 
B equaling dominant Brown, and G = dominant Green, vice versa to g and b where they are recessive.
