A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.
- Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
- When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
- When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
- When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.
Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.

Answer:
As Jane exercises her heart rate and breathing rate increase because he muscles are asking for more oxygen and get rid of more carbon dioxide. More blood is diverted towards the muscles as they need more oxygen for respiration. She needs to burn glucose with oxygen and water to produce energy so she can run. The way she can get this oxygen into her body is through her lungs. Where oxygen from the air diffuses into the blood and carbon dioxide diffuses out.

Xylem is a specialized tissue in vascular plants that is primarily responsible for the distribution of water and nutrients from roots to stems and leaves. The xylem also provides mechanical support and storage to the plant.
Phloem is a specialized tissue in vascular plants that is primarily responsible for the distribution of food nutrients such as glucose (sugar) and amino acids from the leaves to various parts of the plant
