Answer:
0.0139- frequency of heterozygotes in the population
Explanation:
Let q to the power of 2 represents the frequency of the homozygous recessive (aa) = 1/20000 = 0.00005
This, q = √q^2 = √0.00005 = 0.007
Since p + q = 1
p = 1 - 0.007 = 0.993
Using the formula: p^2 + 2pq + q^2
Where 2pq represents the frequency of the heterozygotes, thing we have
2 x 0.007 x 0.993
= 0.0139
Answer:
Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals.

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).

Explanation:
Answer:
The formula is 2n - 2
Since n is 30
= 2(30) - 2
= 60 - 2
= 58
A mutant nullisomic version of this organism would have 58 chromosomes.
A diploid cell missing both copies of the same chromosome exhibits a nullisomic condition or a cell or individual with one chromosomal type missing. Humans having this condition will not live.
Explanation:
A.) the rabbits with the mutation were more successful with restricted food than normal rabbits.
Answer:
The psychological measure that has been used by Dr.singh in this scenario is physiological measures.
Explanation:
Here, Dr. singh a scientist's observations are being listed. Its been given that he wants to study about how the anxiety affects adolescents.
For measuring and observing all the points he measures the heart rates which are causing electrical changes, the respiration and the sweating pattern of individuals.
Also he is going through the hormonal changes in their blood.
So, The psychological measure that has been used by Dr.singh in this scenario is physiological measures.
Physiological measures: An accurate and precise information about an individual's body and its body's functioning like the temperature of skin, sweating, respiration,the heart rate, palmer sweat and also eye tracking by a set of instruments i called the physiological measures.
This measurment is done by identifying and monitoring thr parameter of physical body especially in the major body organs.
