DNA will condense into

aniked [119]

Answer: DNA condenses into chromosomes.

Explanation: Chromatin carefully packs these DNA molecules into stringy-looking structures called chromosomes. If the DNA molecules in cells were not snaked around histones, the molecules would be 6 feet long when placed end-to-end, according to the National Human Genome Research Institute.

Klinefelter syndrome in humans leads to underdeveloped testes and sterility. this is caused by which chromosomal condition?

Anuta_ua [19.1K]

Klinfelters syndrome is when there is an extra X chromosome in males.

So instead of the normal sex chromosomes for males (XY), a male with klinefelters syndrome will have XXY.

I have included a pic of the karyotype to give you a better idea of what I'm talking about.

Hope this helps! I'm happy to help with any other questions you might have :)

Inga [223]

Answer: Option 4.

The fresh water is hypotonic and the salt solution is Hypertonic.

Explanation:

Hypotonic solution is a solution that have little dissolved solutes i.e low osmotic pressure compare to other solution. When a cell is put in hypotonic solution, it take in water and the cell swell up and it does not burst due to it's cell wall thereby becoming turgid or hard.

Hypertonic solution is the solution where the concentration of solute is higher outside the cell than inside the cell. Example is saline water.when a cell is placed in Hypertonic solution it will shrinks because it losses water.

A woman has blood Type A, her baby has blood Type AB: Is it possible that a man who has the blood Type A could be the father? Sh

Wittaler [7]

Answer:

No, it is not possible

Explanation:

Humans use the ABO blood group system where the A and B alleles are dominant over allele O but codominant with one another.

This system is such that;

Type A can only have genotype: iAiA or iAi

Type B can only have genotype: iBiB or iBi

Type AB can only have genotype: iAiB

Type O can only have genotype: ii

According to this question, a woman has blood Type A (iAiA or iAi) and her baby has blood Type AB (iAiB). This means that the father definitely contributed the allele B in order to have a baby with type AB. It also means that, according to the question, IT IS NOT POSSIBLE FOR A "Type A" father to produce that baby (see the punnet square attached).

Note: The father must contain an allele B in his genotype i.e. the father must be either type B (iBiB or iBi) or type AB (iAiB)
