Answer:
a. fatty acids is the correct answer.
Explanation:
fatty acids is NON-polar molecule.
Nonpolar molecules are that molecules which are not soluble in water and fatty acids are not soluble in water.
fatty acids are hydrophobic and the hydrocarbon chain present in fatty acids are nonpolar, thus that's the reason fatty acid is nonpolar.

Carrying oxygen in the blood

The right answer is the kidney will regulate the blood pressure by the renin angiotensin aldosterone system.
The kidney plays a role of selective filtering of the blood. It allows the blood to get rid of its waste. But it also removes water and mineral salts that are in excess.
But the kidney also plays a dynamic role in increasing the pressure, by means of a system called "renin-angiotensin system" which is one of the most powerful natural hypertensives available to the body. Thanks to an enzyme he makes, renin, the kidney will turn a normal blood protein, angiotensinogen, into angiotensin, which causes the vessels in the body to contract and therefore increase blood pressure. This effect is manifested permanently in a disease which is the stenosis of the renal artery, that is to say the permanent narrowing of the caliber of this artery. The kidney, believing that the blood pressure decreases because of this narrowing, will permanently produce renin, which will cause an immediate increase in blood pressure.
Explanation:
When heat is supplied to the liquid through the burner then portion of liquid at the bottom will start to heat first.
This means molecules at the bottom will start to gain kinetic energy and thus intermolecular forces between them start to decrease.
As a result, they will start to move from their initial position. That is, molecules per unit volume will decrease. Hence, density will decrease and the liquid will rise upward.
Whereas when all the molecules of liquid are heated up then it will release energy into the atmosphere.
Thus, we can conclude that this happens to the portion of liquid that first begins to warm.
- It releases energy to the environment.
