Sperm cells are about to be made from a cell with 66 chromosomes. How many chromosomes will the sperm cells have?
Sindrei [870]

Answer:

33

Explanation:

Gametes (sperm or egg) have half the chromosome of a diploid cell. That's why they are haploid cells.

If chromosomes come from a cell with 66 chromosomes, sperm will have 66/2 = 33.

That's why us humans have 46 chromosomes, but our egg or sperm has only 46/2 = 23 chromosomes.

Sloan [31]
The main function of the microscope is to see microscopic objects, or small objects so small the naked eye can't see it. It magnifies the object so our eye can see it.
<span>After discovering and improving the microscope, Robert Hooke discovered cells. This is just one example of how it changed the study of organisms. With the microscope, we could see and find microscopic life like bacteria and see the cells, shape, color, and other materials such as the organelles the organisms were made of.</span>
