Multiple things cause the migration of people.
Economic issues arise:
People run out of jobs and opportunities
(BIGGEST REASON)
Cultural reasons:
Forced intentional migration had occurred in the past on accounts of slavery and political instability
Safety:
More popular reason now is because of war or fights with other countries, the people want to keep their family safe so they move them or move with them

Answer:
The correct answer will be option-B
Explanation:
cDNA library or complementary library is the DNA library constructed from the mRNA which is isolated from the specific tissue.
The genomic library is constructed from the genome sequence of the organism by cutting the gene of interest or the whole genome with a restriction endonuclease and then inserting it into the vectors.
Since the genomic library includes the whole genome which is same in every cell and tissue whereas the cDNA library contains the coding genes expressed in the specific tissue only therefore, Option-B is the correct answer.
The root system, the roots can store energy, anchor the plant to the ground and other surfaces, and they also adsorb and "drink" nutrients and vitamins from the soil. Remember to check yourself.

Answer:
The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)
Explanation:
Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:
Blood type AB - iAiB
Blood type A - iAiA or iAi
Blood type B - iBiB or iBi
Blood type O - ii
According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:
iBi = iB and i
iAi = iA and I
Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:
- type AB (iAiB)
- type A (iAi)
- type B (iBi)
- type O (ii)
