Humans autosomal cells have two copies each of 23 unique chromosomes. Match each of the following cell division events and cell types according to the number of chromatids present. Whereas other events may also be misplaced, you have not matched all of the cell types and events that contain 23 chromatids. A chromatid number of 23 is observed in haploid gametes produced during the second meiotic division.

Please see below    

Explanation:

The number of chromatids have been stated with the respective event when it occurs in that particular number in the following way:  

23 chromatids

primary oocyte arrested prior to ovulation  

spermatozoa    

46 chromatids

oogonium prior to S phase  

92 chromatids

secondary polar body

g1

choices:

a. g2. b. g1. c. m

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
