How do small intestinal epithelial and root hair cells function in nutrient procurement?
Usimov [2.4K]
<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>

What advantage is there in having the special sensory organs confined to the head region?
Dmitriy789 [7]
The answer to this question would be: rapid impulse transmission. 

By having organ near the head, the brain can process the information faster because the length of the nerve that carries the impulse from organ would be much shorter. The nerve also at lower risk of damage since it was shorter.
But it makes the head very important and damage to the head can cause much more problem than any part of the body.

Delicious77 [7]

Answer:

B. MacConkey is both a differential and a selective medium.

Explanation:

Selective media contain the ingredients that allows for the growing of specific microbes while inhibiting the others.

For example MacConkey media facilitate the growth of gram negative bacteria and inhibit the growth of gram positive bacteria. That why E. coli and P. mirabilis grew on the media because these are gram negative and S. saprophyticus does not grew being gram positive.

Differential media allow to differentiate between selected microbes by visual observation.

For Example MacConkey media differentiate between organisms that can ferment lactose to the organisms that can't ferment it. That why E. coli appeared pink on the media because it can ferment lactose while P. mirabilis appears colorless because it usually cannot ferment lactose.
