Answer
After inland population after migration allele frequency is 0.62 or 62%
Explanation:
Given,
Coastal striped phenotype freq. = 0.22
ss = 0.22
= 0.22
Similarly, inland striped phenotype freq. = 0.43
= 0.43
= 
= 0.4690
= 0.47 i.e. 47%
= 0.655
= 0.66 i.e. 66%
the migration range (m) is given as 20%
m= 0.2
allele freq. after migration = pre migration + ∆q
here,
∆q = change in the allele frequency
or
migration of allele freq. from coastal to inland
=
= 0.2 (0.47 – 0.66)
=
= - 0.0382
∆q = -0.04 i.e. 4%
1. The cells would be for repair.
2. Cells grown in serum free or reduced medium are termed donor cells starved. It is done by biologist to synchronize all the cells in same phase of cell cycle.
Explanation:
1. If a fully developed mammary gland cell divides it would be daughter cells for repair by mitosis or during turn over of normal cells.
2. The term starved for donor cells means to deprive the cell of nutrients by growing them in reduced or serum free medium.
The reason biologist use this technique is to synchronize all the cells in same phase of the cycle as Go phase of cell cycle.
3.In the egg containing the donated somatic cell is reprogrammed by host machinery. The enucleated egg incorporated with somatic cell nucleus is given an electric shock. The cell becomes viable ready to divide and produce a viable organism.
After continuous mitotic divisions, cell becomes blastocyst.
This furthur divisions will produce organism not ball of mammary gland cells. The plueripotent stem cells are obtained by this technique.
Answer:
B. The population size will decrease
Explanation:
Abiotic factors may include temperature, sunlight and water. If conditions are too cold for the organisms living there, they may perish. If the amount of sunlight decreases, plants will not be able to produce enough glucose through photosynthesis. If the amount of water decreases plants may bot have enough water to photosynthesise and animals will have to compete for water.
