Answer:
The true statement is <em>Hydrophobic side chains are usually in the interior of the native structure</em>.
Explanation:
In the native structure of a protein, the hydrophobic side chains of aminoacids- such as leucine (Leu), alanine (Ala), methionine (Met), and others-are located in the interior of the structure. They are buried inside the structure, whereas polar side chains are exposed to the outside in the structure, and they interact with water molecules.
Regarding the other statements, entropy-as a measure of disorder of a system-is very important in protein stability as we know that native conformations are more ordered systems, with lower entropy and higher stability. Aminoacids in the protein structure interact each other through Van der Waals interactions and hydrogen bonds.

In the energy pyramid for any given ecosystem, the most energy available is at the bottom and the least energy available is at the top.
At the bottom of the energy pyramid are the producers (plants and other photosynthetic organisms). The first group of organisms that consume the producers are called the primary consumers (herbivores). The next group of consumers are the secondary consumers, and then the tertiary consumers and quaternary consumers.

Answer:
I think the answer is A population is made up of only one species. A community is made up of all species in an area.(the second one)
Explanation:
Population is a group of organisms of
one species living in the same area at
the same time.
Community is all of the population of
different species in an area.
