cause they act like they cant seem to see or help

Answer 2

@LitOneForPresident yeah i do the same thing... and i think the answer b not c, just saying

Answer 3

y?

Answer 4

yes

Answer 5

because in the cell cycle, 4 is diploid and 2 is haploid

During gamete formation, each allele of a pair for a gene moves to separate gametes. Which principle is indicative of this statement?Select one of the options below as your answer:A. The principle of independent assortmentB. The principle of segregationC. The principle of unit characters
