I think it's D: ribosomes and mitochondria. do you go to K12?
Answer:
see in explaination
Explanation:
Density (D) is a quantity defined as mass (m) per unit volume (v): D = m ÷ v. Since these three quantities are related, you can find one of them if you know the other two. This is more helpful than it sounds because density is often a known quantity that you can look up, assuming you know the composition of the material.
Calculations are straightforward for solid objects, but things get more complicated for liquids, where density changes with temperature, and for gases, for which density is dependent on temperature and pressure.

Hydrophobic amino acids are buried at the core of a water-soluble globular protein.
<h3>What makes globular proteins water soluble?</h3>
Numerous hundreds to thousands of amino acids are used to make proteins. The arrangement of amino acids within a protein molecule determines its ultimate form. A protein molecule is classified into two classes—fibrous proteins and globular proteins—based on its final shape.
The structure of globular proteins resembles a ball or a globe. A globular structure is created by the folding of different amino acid chains. The two most significant globular proteins present in the human body are hemoglobin and myoglobin. The hydrophobic side chains of the amino acids are hidden inside the cores of the domains whereas the hydrophilic side chains are located on the surface of the molecule thanks to the arrangement of the amino acids.
The hydrophobic amino acids can be buried in the center of globular proteins due to interactions between the hydrophobic groups in their side chains. This is the fundamental property of globular proteins that makes them water soluble.
Examples of hydrophobic amino acids are phenylalanine, alanine, valine, etc.
