Answer:

Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis

Explanation:

Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.

Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.

Aleonysh [2.5K]

Answer:

Option B, $18.11 \frac{N}{cm^{2}}$

Explanation:

Given-

The average surface area of one foot pad of an elephant is $2920$ $cm^{2}\\$

Weight of an Asian elephant is $52900$ newton

As we know, pressure is equal to total weight divided by total area of the surface on which it is concentrated.

Thus, pressure on one foot pad of elephant is $\frac{52900}{2920} \frac{N}{cm^{2}} \\$

$= 18.11\frac{N}{cm^{2}}$

Hence, option B is correct answer

Which part of an individual villus forms part of the lymphatic system and absorbs fats from the lumen of the small intestine?

Lostsunrise [7]

I believe the answer is the lacteals.
Lacteals are structures that are in the middle of each villi; they are lymphatic capillaries that absorbs dietary fats in the villi of the small intestines. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. The lacteals merge to form larger lymphatic vessels that transport chyle to the thoracic duct where it is emptied into the blood stream at the subclavian vein.
