Question 8

Libidio

Answer 8

Desire to mate

Question 9

Meiosis

Answer 9

The 2 divisions which precede the formation of gametes in which the members of each chromosome pair separate and the chromosome number in the resulting daughter cells is reduced to half somatic number as distingusined from ordinary cell division

Question 10

Metamorphosis

Answer 10

Change of shape or structure a transition from one developmental stage to another
