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.

This statement is false.
Grass and Fruit Tree are all living organisms. When you say living organism, it contains life. Grass and trees do grow and needs nutrients the same as human, they also contribute to the environment to give life.
The start codon is the AUG and codes for the amino acid methionine.
Answer:
Mutations influence evolution by changing the DNA that produces a variation within the gene.
Explanation:
- Mutation is the alteration or change in genetics of an organism.
- An alteration of singe base unit in DNA might also cause mutation.
- It is very important fact that only herediatary mutation is responsible for the evolution, no all mutation influences the evolution.
- The change in eggs or sperm cell is sequentially transferred to the further generation, ultimately resulting in the evolution.
<span>reformists muscle originates from the anterior front part of the sacrum, the part of the spine in the gluten region, and from the superior margin of the greater sciatic notch as well as the sacroiliac joint capsule and the tuberous ligament. Hope this helps :)))))))))</span>
