C) make proteins
Amino acids contain nitrogen and amino acids are used to make proteins.
The villi of the small intestine use active transport to take up nutrients after concentration has reached equilibrium.
<h3>What is Active transport?</h3>
Active transport may be defined as the process that occurs against the concentration gradient and is mediated by carrier proteins. Metabolic energy is used to move ions or molecules against a concentration gradient.
During the process of digestion, the villi in the small intestine enthrall the soluble nutrients gradually. Over time, the concentration of nutrients in the villi acquires an equilibrium with the concentration in the gut. Until here, the nutrient uptake is carried by the process of passive diffusion.
But after attaining the equilibrium, the nutrient uptake is carried by the process of active transport.
The complete question is as follows:
What part of the body uses active transport to take up nutrients after concentration has reached equilibrium?
- Lungs
- Stomach
- Small intestine
- Liver
Therefore, the correct option for this question is C, i.e. small intestine.

#SPJ1
The correct answer is B. Glycolysis
It is a process that deals with dissolving sugars which leads directly into the Krebs Cycles.
The bulky shape of fat cells makes them ideal for filling spaces of connective tissue. The fat cells represent a type of connective tissue.
The adipose tissue is a type of connective tissue composed of fat cells known as adipocytes.
These cells (adipocytes) are specialized cells that store fats, which can be produced by the human body or obtained from the diet.
The shape of the adipocytes can be spherical, oval, polyhedral (as part of adipose connective tissue), etc.
