One of the roles of blood is to transport nutrients around the body and deliver molecules such as sugars and lipids to cells. A

scientist makes the observation that since blood is composed of water, sugars tend to dissolve, while lipids aggregate. Which of the following claims would be the most useful way for scientists to explain this phenomenon?
A) Smaller and simpler molecules such as sugars tend to dissolve, while larger and complex molecules such as lipids aggregate out.
B) When water is heated, it takes less heat to dissolve sugars than it does to dissolve lipids.
C) Water molecules stay close together as a result of adhesion, while lipids aggregate out as result of cohesion.
D) Water dissolves some molecules while causing the aggregation of others because of hydrophobic and hydrophilic interactions.

Answer:

D) Water dissolves some molecules while causing the aggregation of others because of hydrophobic and hydrophilic interactions.

Explanation:

Sugars tend to dissolve, while lipids aggregate out because sugar has hydrophilic (water loving) interaction with water and on the other hand lipids have hydrophobic (fear of water) interaction with water. Water is a polar solvent and only polar solute dissolve in it due to phenomenon of like dissolve like, while lipids does not dissolve in it because lipid is non-polar in nature. In this case, sugar is hydrophilic while lipids is hydrophobic.

What are the four carbon macromolecules the body uses and makes?
aliya0001 [1]

Living things are made of types of molecules, known as macromolecules.

There are four major classes of biological macromolecules:

carbohydrates

lipids

proteins

nucleic acids

Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules. In combination, these biological macromolecules make up the majority of a cell’s dry mass. (Water molecules make up the majority of a cell’s total mass.) All the molecules both inside and outside of cells are situated in a water-based (i.e., aqueous) environment, and all the reactions of biological systems are occurring in that same environment.
