Answer:
A-complete dominant
B-codominance
C-Incomplete dominant
D-codominance
E-Incomplete dominance
Explanation:
Complete dominance- This is when a dominant Allen completely mask the effect of a recessive allele and the offspring express its phenotype E.g . A pea plant with all purple flowers and a pea plant with all white flowers produce a pea plant with all purple flowers.
Incomplete dominance- This occur when the dominant allele doesn't fully dominate over the recessive allele and the offspring shows a combination of both allele(a phenotype different from the parent)
E.g A red snapdragon and a white snapdragon produce a pink snapdragon.
Codominance- This occur when both allele express itself. The phenotype of the offspring consists of both allele example AB blood group
In a hypotonic solution
Explanation:
Contractile vacuoles are used mainly by protozoans like an amoeba in osmoregulation. When the organism environment becomes hypotonic to the cell's cytoplasm, the contractile vacuole pumps more rapidly. This is because, in the hypotonic environment, more water is getting into the cell by osmosis. To maintain the right osmotic pressure in the cell more water is needed to be pumped out – this is a function of the organelle.
Endangered is when group of species are at the edge of extinction.
Threatening is when group of species are at the risk of extinction in future.
