Answer:
This statement is not correct because the Na+ equilibrium potential remains the same, it is only depends on concentration gradient.
Explanation:
Na+ influx will increase, but Na+ equilibrium potential will not change because the concentration of K+ ions are high inside the membrane and that of Na+ ions are high too outside the membrane. Membrane potential will be generated that helps in the diffusion of the ions through the pore in both in and outside of the cell. When the concentration of Na+ ions increase, Na+ ions diffuse from outside to the inside of the cell therefore increase the influx
I think the correct answer would be the last option. People with one sickle cell allele are not likely to get malaria. This would be an example of genetic drift. It is one of the mechanism of evolution which involves the change in the frequency of an allele in a certain population due to the random sampling of the organisms. It is when a certain trait is being spread by chance rather by natural selection. Sickle cell is classified as an autosomal recessive disease that is caused by hemoglobin. It is a disease that is inherited depending on how the alleles are received. So, it can be inherited by chance.
Answer:
Arteries experience a pressure wave as blood is pumped from the heart. This can be felt as a "pulse." Because of this pressure the walls of arteries are much thicker than those of veins. ... The tunica media is smaller in relation to the lumen than in arteries.
