Answer:

B

Explanation:

Great variations in temperature and pH from the optimum that an enzyme needs can affect its function. pH affects ionization of the functional groups of amino acids. The interaction of charges of these amino groups helps in stabilizing loops such as those of beta sheets and alpha helices and give the protein its an appropriate shape to function.

Temperatures, on the other hand, while it does not change the ionization of the functional side groups of amino acids, it breaks these bonds of the interactions by giving the molecules enough energy to break free from these bonds hence denaturing the protein.

Answer:

Option (c) is the correct answer to this question.

Explanation:

Nonrandom mating happens when the chance of matting two individuals in a given population isn't really the same across all potential human pairs. Outcompeting-Individuals are more likely than family members to match with distant relatives. This is somewhat less prevalent.

Organisms may tend to match with someone of the same genotype or of genetic background in non-random mating. Non-random marriage does not alter the dos fluctuations in the community by itself, though it may modify the fluctuations of the gene.

Other options are incorrect because they are not related to the given scenario.

What regulates breathing rate and how does the body sense when to breath?
Marina86 [1]

Answer:

Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).

Explanation:

The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).

Answer:

The properties and structure of the bacteria is different so each of them would react differently. The antibiotic might help one of the bacteria while eliminating the other in the process.
