Answer:
Both are type of natural selection and ultimately lead to selection of a set of phenotype over the entire available genotype spectrum.
Explanation:
Both the stabilizing selection and directional selection are two forms of natural selection
Also in both the selection process, a new population with a better fitment to the prevailing environmental and physical conditions evolves.
In stabilizing selection, an average phenotype is selected over extreme variation. However, by this process of selection the genetic variance of the population will decrease.
However in directional selection, phenotypes at one end of the existing variation are selected over the entire spectrum
Answer:
C)radial symmetry.
Explanation:
The central nervous system (CNS) is a part of the nervous system, it comprises the spinal cord and the brain. The brain plays in an important role in controlling most functions in the body such as movement, memory, speech etc.
Animals that have bilateral symmetry have a central nervous system because of the presence of the brain. But animals with radial symmetry such Cnidarians which include corals and jelly fish, do not have a central nervous system. Instead of the presence of neurons, they possess nerve nets.
Answer:
A. Purple
Explanation:
Since purple flowers are dominant to white flowers, the letter for it need to be capital too to signify dominance. So purple flowers is PP.
A common cause of iron deficiency anemia in adult hood is
blood loss and lack of iron in the body. Blood loss is usually the cause
because of bleeding in the GI tract, intestinal bleeding and chronic occult
bleeding. Lack of iron in the body is also a cause because a body is in need of
iron and if it does not exceed the required iron in the body, it may result to
iron deficiency.
