The circulatory system helps the excretory and digestive system do their jobs because the waste from the blood in the circulatory system is eliminated from the body through the excretory system, and the nutrients absorbed by the digestive system are transported through the blood.

Bc it is
<span>The Epipelagic
zone is the one closest to the surface and is the brightest. It extends
to 200 meters and contains both phytoplankton and zooplankton that can
support larger organisms like marine mammals and some types of fish. So the answer to your question is B.</span>

<h2>
Genotype is the set of genes( allele) of an organism.
</h2><h2>
Phenotype is the physical expression of the genetic composition of an organism.
</h2>
Explanation:
Genotype: 1. It is the genetic composition of an organism, means it is the set of genes( allels) of an organism's DNA, which is responsible for a particular trait of an organism.
2. Genotypically, an organism can be homozygous(dominant or recessive) or heterozygous. Some Alleles are dominant over other, means some can be dominant or other can be recessive.
3. Genes are responsible for all the traits in an organism, and these traits are inheritable. All the offsprings inherit all traits from their parents.
Phenotype: 1. Physical expression of the genetic composition of an organism resulted as phenotype.
2. It is the physical expression of genes (alleles) which are responsible for any trait.
