Which one of the following is a major difference between the circulatory systems of earthworms and fish?
labwork [276]
<span>a. Fish have a single central heart; earthworms have several hearts.

</span>
Multi cellular organisms are made up of billions of cells each specialized to a unique role and these cells are organized into structural and functional units such as tissues and organs.
For each cell and organ to function optimally, it requires oxygen and nutrients and needs carbon dioxide and  metabolic waste taken away  in a  continuous, never ending  process.
<span>A mechanism  is needed to accomplish the important function of transporting the relevant materials to and from the cell. The circulatory system fits this  bill splendidly. It is a specialized organ system which allows blood  and lymph to flow through the entire body carrying nutrients such as glucose, amino acids and electrolytes as well as oxygen to each cell, at the same time carting away carbon dioxide and all sorts of metabolic waste over to excretory organs  to be expelled from the body.

Why human with heterozygous genotype will have the dominant phenotype?
AnnZ [28]

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.
