Answer:
Explanation:Population genetics is the field of biology that studies allele frequencies in populations and how they change over time.
In order to determine the results from a father who is homozygous recessive for the tongue rolling trait, T, and a mother who is heterozygous for the trait, a Punett square can be used to determine both the resulting genotype (allele combination) and phenotype (observable characteristics). The results are 50% Tt and 50% tt. Thus, the cross would result to 1:1 ratio of tongue rolling to non-tongue rolling offsprings.
Answer:
Cellular energy
Explanation:
Osmosis is the movement of water from a less concentrated to more concentrated solution across a semi-permeable membrane. Cellular energy is not required in osmosis because it is a passive process. Osmosis is technically more or less the selective diffusion of water molecules across a membrane that selectively locks out other larger molecule like ions. Water will, therefore, move from the solution where there are more water molecules to the solution with fewer water molecules.
