Answer:
Sometimes, gene mutations prevent one or more of these proteins from working properly. By changing a gene’s instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body
Explanation:
The answers that apply are;
new allele combinations were advantageous in the presence of
parasites with high mutation and reproduction rates.
sexual reproduction increased genetic variability and
survival in a changing environment?
Sexual reproduction increases genetic variability due to combinations of alleles from the parents to the
offsprings. This increases the chances
that a particular combination may be able to confer resistance to the
disease-causing bacteria and hence increase the survival of the roundworms population.
Answer:
The function of segregating the interior of the cell enclosure to the outside is known to occur by the function of the plasma membrane. These molecules comprising the plasma membrane is none other than lipids. Highly enriched hydrophobic tails of lipids interact with other lipids in a typical bilayer arrangement to regulate and control gene expressive Molecular and other crucial ions from moving in.
Answer:
enzymes loose their form in both unsuitable ph and temprature.
Explanation:
at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.
low ph solotions contain lot of H+ and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes. some Enzymes like pepsin works perfect in acidic environment ( ph=2) while others might work at high ph or average ph( like Trypsin works well at ph=7).
The answer is: A. Chromosome
