A. Plants use capillarity to move water from their roots to their leaves.
<h2>Answer </h2>
Neutral Variation
<u>Explanation</u>
Point mutations in noncoding regions of DNA result in neutral variation. The alleles which neither considerably sum to nor exceedingly lower from body consistency. It is the accumulation of such alleles located within a community that can be explained as expressing neutral variation. Neutral Variation implies in various alleles that are existing at an assigned genetic locus because those alleles are not distinct by natural selection.
Answer:
Option C
Explanation:
Long term hunting has led to following
a) Reduction in population size and hence the gene pool
b) Causation of Bottleneck effect
Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.
Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.
Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism
Option C is correct
The Process in which pesticides are stored in body tissues is known as Bio-Accumulation.
When pesticides get into our body through eating food which is not go through the process of metabolism or which is not excreted, that is stored in fatty tissues of the body and as time passes we may build up high concentration of pesticides in our body. Pesticides are the chemical compounds used for killing pests, bacteria etc.
