Cells divide at different rates. The fastest bacteria can divide every 20 minutes. No wonder you can feel sick with food poisoning within hours of eating undercooked food! On the other hand, some nerve cells in your body do not divide much at all. The nerve cells in a 100-year old person could be close to 100 years old! Read the examples of cell division below. Place a check mark next to the ones that represent MEIOSIS. No partial credit. You must select ALL the examples that relate to meiosis. * 20 points
A plant produces pollen cells with half the chromosomes of the parent cells.
A bacterium divides to make two identical daughter cells.
A skin cell divides rapidly to replace tissue damaged by a scrape.
A cell duplicates its genetic material once and then divides twice to make 4 daughter cells.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

i think the answer is

mass

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
