Answer:
44
Explanation:
A somatic cell is diploid - it has 46 chromosomes. Half of these are from the mother, so there are 23 maternal chromosomes
A sex cell (gamete) is haploid - it has 23 chromosomes. There are (usually) two sex chromosomes in a diploid genome, either XX or XY, so there is one 1 in a haploid cell, giving a total of 22 autosomes
Barr bodies are inactive X chromosomes in a female somatic cell. This occurs to control dosage compensation (otherwise all the genes on the X in females would be expressed twice as much as they are in males). In a healthy female, there is normally one Barr body
A person with Kleinfelter's syndrome has two X chromosomes and one Y (XXY). They are biologically male, but have two X chromosomes. Therefore, one of these becomes a Barr body, as in females.
23 + 22 - 1 = 44

Answer:
1. Damaged bases are recognized.
2. Part of a single strand is excised.
3. DNA polymerase I adds correct bases by 5′ to 3′ replication.
4. DNA ligase seals the new strand to existing DNA.
Explanation:
Every microscope will let you see anything that is smaller than the naked eye can see. The word microscope is a compound word. The word micro means small and the word scope means to see so the word microscope kind of means “to see small things”. Hope this helps!
