<span>Like DNA, RNA polymers are make up of chains of nucleotides *. These nucleotides have three parts: 1) a five carbon ribose sugar, 2) a phosphate molecule and 3) one of four nitrogenous bases: adenine, guanine, cytosine or uracil.
i hope this helps if it does can i get brainliest answer</span>
Infiltration is the step in the water cycle that involves matter changing form
The answer is <span>The q allele will go up.
Let's assume that the population is in the Hardy-Weinberg equilibrium and there are only two alleles of some gene. </span>The Hardy-Weinberg principle can be expressed as p + q = 1 where p is the frequency of the p allele and q the frequency of q allele.
Let initial frequencies be:
p = 0.6
q = 0.4
p + q = 1
0.6 + 0.4 = 1
Now, after the environmental change, the frequency of the p allele has gone down, for example p = 0.3
So, p goes from 0.6 to 0.3.
The frequency of the q allele can be calculate using Hardy-Weinberg principle:
p + q = 1
q = 1 - p
q = 1 - 0.3
q = 0.7
Thus, q goes from 0.4 to 0.7.
Answer:
to preserve its stability.
to avoid cross contamination.
Explanation:
Biological evidence refers to all biological materials such as hair, tissue, bones, teeth, blood or other bodily fluids etc. These biological materials are collected from the site of crime. These evidences helps in finding the criminals. These biological evidences has to be kept at safe place in order to avoid contamination and preserve its stability so it can be used for solving the problem.
