John, an African American student, has chosen to incorporate exercise into his daily routine to prevent health issues. Based exclusively on his ethnicity, what is the most likely basis for his decision?

Find explanation below.

Explanation:

Ethnicity is a term used to describe a group of people with shared characteristics like culture, place of origin, language, religion, beliefs, etc. African Americans are an ethnic group in the United States, falling into the category of Hispanics and Latinos. They have their roots in Africa.

Africans have been found to be predisposed to certain health problems most likely as a result of adaptations to the environment they lived in. For example, they have a higher ability to conserve salts in their bodies compared to whites and this factor predisposes them to diseases like high blood pressure.

This might be why John has chosen to incorporate exercise in his daily routine to prevent health issues such as this.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
