Answer:
The chance of a normal couple having a child with down syndrome is 1 to 600 births.
Explanation:
Down syndrome is a genetic flaw that occurs when the fetus is being formed.
A human cell considered normal has 46 chromosomes, divided into 23 pairs. For some unknown reason, an error may occur at the beginning of embryonic development and an extra chromosome is created, which binds to par 21. The result is cells with 47 chromosomes. This causes the said syndrome.
It is important to know that this failure happens at random. It is nobody's responsibility. It has not been proven to date that lifestyle, actions during pregnancy, smoking, drinking, medicines, environmental factors or kinship between the couple can influence this occurrence. She is not contagious either. The likelihood of a normal couple having a child with the syndrome is approximately 1 to 600 births.

Answer:
answer is Bthe high tides will be much higher than usual
Maybe not because after light increases stomas will decrease and after that plant leaf will take less co2 and less co2 mean less synthesis in the plant.
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.
