Which best describes the factors that affect a phenotype? a. phenotype is only controlled by the genotype. b. the phenotype is determined only by the environment. c. nutrition is the only thing that determines the phenotype. d. the genotype and the environment both affect phenotype.

D. The genotype and the environment both affect phenotype.

Explanation:

Phenotype is the outward expression  or make up of an organism. The phenotype is simple the physical outlook of an organism. It is as a result of the combination of two major factors which are the genetic make up(genotype) and the environment. When both combines, an organism's pheontype is built and produced.

If the environment is lacking, a gene might not successfully express itself in an organism. Also, an organism might have the right environment but the gene is lacking.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

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.
