Answer 4

false

12 to 24 hours after it is casted out of the ovary

12 to 48 hours after ejaculation

Question 16

how long is super sperm viable

Answer 16

72 hours after ejaculation

Question 17

Question 18

how long does it take for the sperm to get to the uterine tubes

Answer 18

1 to 2 hours

Question 19

How are sperm able to break down the corona radiata

Answer 19

when sperm reach the oocyte, hundreds of their acrosomes rupture, releasing enzymes that break down the “cement” that holds the follicle cells of the corona radiata

Question 20

what happens to the sperm that reaches the oocyte’s membrane

Answer 20

it’s head (nucleus) is pulled into the oocyte cytoplasm

Question 21

how does the oocyte change after sperm penetration

Answer 21

the oocyte nucleus completes the second meiotic division, forming the ovum and a polar body

Question 22

fertilization

Answer 22

occurs when genetic material of a sperm combines with an ovum to produce a zygote

- deepening of the voice due to enlargement of the larynx - increased hair growth all over the body, and particularly in the axillary and pubic regions and the face - enlargement of skeletal muscles to produce the heavier muscle mass typical of the male physique - increased heaviness of the skeleton due to thickening of the bones

Question 33

After implantation

Answer 33

- chorionic villi+ uterine tissue = placenta - amniotic fluid fills placenta - endocrine replaces c.l, which is done by the end of 2nd trimester - placenta takes over pro. - by week 9= fetus
