<span>Villi are hair-like structures covered with epithelial cells measuring 1.5 mm that line the mucous inner membrane of the small intestine. The epithelial cells of the villi contain microvilli and are responsible for the absorption of nutrients. Being so small and numerous, they effectively increase the absorptive surface area of the small intestine. When the surface area increases, this is the time they absorb the nutrients.
As for plants' root hair cells, they receive nutrients through osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. The absorbed water and minerals are transported through the roots to the rest of the plant where it is used for different purposes: It is a reactant used in photosynthesis.
As we can see, both of them utilize increasing their surface area.</span>
1. nucleus 2. ribosome
Here's why:
The nucleus is the central part if the cell that contains the genetic materials. The nucleus is often described as the "brain" of the cell. Ribosomes are cell structures that make protein. They can be found in the cytoplasm or in the endoplasmic reticulum.
I hope this helps:)
The answer is C. because the rest are negative downsides.
Answer:
Explanation:Antibodies work by recognising and sticking to specific proteins, such as those found on the surfaces of viruses and bacteria, in a highly specific way. When the body encounters a microbe for the first time, immune cells produce antibodies that specifically recognise proteins associated with that particular microbe.
