Nutrients and waste both enter and leave cells through a process called
a. effusion b. diffusion c. fusion d. emulsion

Nutrient and waste materials use a process of diffusion to enter and leave the cells during metabolic processes.  

Further Explanation:

Diffusion is the process that allows movement of water, nutrients, and waste material across the cellular membranes. It also allows gaseous exchange. These smaller molecules can be transported across the membrane. There are two types of diffusion processes;

First one is a type of movement that is along the concentration gradient and does not require any specialized carrier systems. Some of the molecules that are transported this way include water and gases. The second type of diffusion, facilitated diffusion, requires a carrier protein to assist the movement of molecules such as glucose. Both are examples of passive transport.

Effusion is the collection of fluid in a specific space where it is not supposed to be. For example pleural effusion is the collection of fluid in lungs.

Fusion is the process of combining to form something new. For example, cell fusion is the process where two uninuclear cells combine to form a multinucleated cell.

Emulsion is a mixture of two or more liquids that are immiscible. These liquids do not mix properly in normal conditions. For example, when oil is mixed with an aqueous liquid, it forms an emulsion of oil.
