1.) The name of my organism is the Tyrannosaurus Rex.
2.) The T-Rex went extinct 65 million years ago when the meteor hit the earth.
3.) We couldn't have done anything about this.
4.) The T-Rex lived mainly in North America and Aisa, in forests with plant-eating dinosaurs.
5.) The T-Rex was tall and stood on 2 legs. the other legs were usually up off the ground for eating its prey. I had really sharp teeth for eating meat.
The answer is stabilizing selection.
<span>Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.</span>
Stabilizing selection favors heterozygotes Ss, disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.
Energy in the initial form of glucose is used with oxygen to produce carbon dioxide, water and energy in the form of ATP which is taken up by the cell in order to perform cellular processes.
