In a few words, describe the differences in a recessive phenotype and a dominant genotype.

A dominant allele is always expressed or seen.A recessive allele is only expressed when in a genotype pair.

Explanation:

Recessive phenotype is that type of phenotype that is expressed by an organism only  when both the alleles of a genotype are recessive. Dominant genotype is that type genotype were either one of the alleles or both the alleles are dominant.

Explanation:

not only is it colder, it also becomes darker, less salty, and more dense.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
