Why would natural selection not occur without genetic variations in species

Biology
2 answers:
Fudgin [204]3 years ago
7 0
Natural selection only occurs when there is a superiority within a species set. If there is no genetic variation, no single animal is any better than the next, making the presence of superiority impossible and survival left up to chance. In this case it would be considered genetic continuity.

Natural selection cannot occur without genetic variation because without genetic variation all the species would be the same and as such there would be no fitter species thus nature cant select one for survival.

Sonbull [250]

Answer:

Pancreatic juice, NaHCO₃.

Explanation:

The buffers are the chemical solution which neutralizes the acidic effect and the human body also produces the biological buffers which help maintain the pH.

The pancreatic juice secreted by the pancreas gets drained into the duodenum of the small intestine and neutralizes the effect of the acidic content in the stomach bolus.  The pancreatic juice contains the sodium bicarbonate which neutralises the effect of the HCl.

Thus, Pancreatic juice, NaHCO₃ is the correct answer.
