Stiffness in the neck can make it difficult for drivers to look behind when they are backing up.
Answer: .374 and .626
Explanation:
5. total number of alleles = 4712 + 2816 = 7528
frequencey of B allele = B allele / total number of alleles --> 2816/7528 = 0.374
6. total number of alleles = 4712 + 2816 = 7528
freq of b allele = b allele/total number of alleles --> 4712/7528 = 0.626
We can confirm our answer as correct because if we add up the answers to 5 and 6 we should get one:
0.374 + 0.626 = 1
It is impossible as there is a loss of energy between the transfer of energy between flogs and <span>mosquitoes. This ecosystem would never be sustainable or in equilibrium. There is also no primary producer within this ecosystem. No ecosystem can exist without some initial source of energy that would be obtained using solar or chemical energy. For terrestrial ecosystems, plant primary producers would normally provide the initial energy into the ecosystem. </span>
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.
