Answer:
Differential reproduction leads to a change in allele frequencies over time. This occurs because of natural selection favoring "successful" individuals that produce more viable offspring.
The sickle-cell allele is maintained in populations exposed to malaria through balancing selection, since heterozygous individuals have protection against the disease.
Answer:
Because the energy in glucose can not be used by the cells until it is being stored in ATP
Explanation:
<h3>Oxidative Phosphorylation</h3>
Explanation:
The process by which ATP is generated by utilizing the large amount of energy released during the transfer of electrons from NADH or FADH₂ to the O₂ through a series of electron carrier present in the mitochondrial membrane is called oxidative phosphorylation.
The process of electron transfer is accompanied by the pumping of protons across inner membrane of mitochondria, from the mitochondrial matrix to intermembrane space establishing electrochemical proton gradient.
The ATP synthase complex present in the mitochondrial membrane allows the protons to move down the proton gradient as a result enough energy is released to add a phosphate group to ADP and form ATP inside the mitochondrial matrix.
Answer:
The chloroplast is involved in both stages of photosynthesis.
Explanation:
The light reactions take place in the thylakoid. The dark reactions then occur outside the thylakoid. In these reactions, the energy from ATP and NADPH is used to fix carbon dioxide (CO2).
