Answer:
The correct answer would be phenotypic variation.
Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.
Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.
In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.
Answer:
Option A, Donates H+ ions when conditions become too basic and accepts H+ ions when conditions become too acidic
Explanation:
Buffer solutions have the ability to maintain stability of pH of the solution. They resist any changes in the pH of the solution on addition of an acid or a base component or solution.
Every buffer solution has a buffer capacity and range. Buffer capacity depicts the amount of acid or base solution is required to change the pH of the solution by 1
.
Hence, option E is correct
Living beings -reproduce , grow and develop, made of cells , store and use energy, adapt to their environment , responds to their environment or stimuli
Non living beings- do none of the above they do not eat , grow , develop, have cells store or use energy , they do not adapt to their environment, and they don’t respond to their environment or stimuli
