Answer:
Option b) Hydrophobic interactions between phe106 and ile108 of one monomer and ile272 and leu273 of the other monomer. Ionic bonds between arg96 and arg103 of one monomer and glu300 and glu304 of the other monomer.
Explanation:
In the structure, there are ionic hydrogen bonds and salt bridges between the 42, R221, and D24. These interactions have a dynamic impact on the activity and structural stability of the protein nature.
The hydrophobic interactions at the interfaces also contribute in the stabilization of the protein structure.
Answer:
b. The individual's' genetic composition
Explanation:
Natural selection is an occurrence in nature in which organisms with genes that have mutated to adapt to certain ailments, survive better than their mates. J.B.S Haldane made a hypothesis that this phenomenon of natural selection accounted for why people in Africa had developed resistance to malaria. Their hemoglobin, proteins, and other compounds that are necessary for the function of the red blood cells had been modified so that they would not easily be infiltrated by malaria parasites.
A.C. Allison confirmed this in his experiment which showed that people who had sickle cell mutations in the gene, beta hemoglobin were mostly found in regions where malaria was prevalent. Their genes had also been modified such that they were resistant to malaria.
1. grow more
2.do organisms make plants grow faster
3. what type of organism supports the plant the best
The integumentary system (skin) has been called a membrane and an organ but, it is generally considered a system because it has organs that work together as a system. It is sometimes considered an organ because it contains several types of tissues and a membrane and it covers the body.
