Answer:
A. All channel movement requires active transport to equalize the cell
Explanation:
Active transport is necessary for the sodium-potassium pump to work because all channel movement requires active transport to equalize the cell.
Answer:
The correct answer is - less efficient signaling.
Explanation:
Second messengers are the molecules that help in transferring the information in the form of intracellular signal that has come from external stimulus.
Second messenger molecules should be short-lived as the concentration of these molecules should be decreased fastly so the cell can be available for other stimuli mediated by the same second messenger.
With increased lifetime, signaling will be less efficient as another stimulus cannot be detected.
Thus, the correct answer is - less efficient signaling.
Endangered species with very small populations are especially at risk of loss of genetic diversity due to option(d) i.e, genetic drift.
A species that is threatened with extinction in the near future, either globally or within a certain political jurisdiction, is known as an endangered species. Invasive species, habitat degradation, poaching, and other issues may put endangered animals in danger.
Genetic drift is the arbitrary change in the frequency of a gene variant in a population. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Additionally, it has the potential to make previously uncommon alleles far more common and even fixed. Drift lowers genetic diversity in populations, which may limit a population's capacity to adapt to new selective pressures. In smaller populations, genetic drift is more pronounced and has more severe consequences. Particularly in the case of rare and endangered species, this effect is significant.
The complete question is:
