Answer:

d. Lysine is replaced by tryptophan (nonpolar)

Explanation:

Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.

If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.

Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.

Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.

Answer B:

The explanation for this is that they have populations that increase in number and have their niches realized and constant resources necessary to develop the species in this way, considering the dominant species in the area and the one that predominates, in the case of fundamental niches. , they are necessary and even obligatory niches for many populations, which if populations do not go to them, they die, extinguish, or decrease their number, that is why in the face of this reality made up of a fundamental niche since it is fundamental to persist life of the population.

Answer c:

Two key principles are: one, maintain the equilibrium, that is why one seeks to have an environmentalist position preserving nature, and two considering that we are part of that balance but that does not give us the right to break it with environmental contamination, intervention of natural food systems and many other factors.

- dilated cardiomyopathy, a type of heart failure, in which the heart gets larger and cannot pump blood efficiently and the last one is

- hypertrophic cardiomyopathy, in which the heart muscle walls thicken and problems with the relaxation of the muscle, blood flow, and electrical instability develop

these are only a few that can harm or even kill a living thing like and animal or person these things are really harmful.

I hope this helps you!!
