2. In laboratory testing using a HER2-positive breast cancer cell line, the researcher has seen early success with the new treatment. In the lab, the researcher incubated the HER2-positive cell line in a petri dish. After the cells had time
to grow, they were treated with a dose of Herceptin. The number of cells that had undergone apoptosis, or cell death,
was then examined to determine the effectiveness of the treatment. Examine the data collected below then calculate
the mean. Go to the next page to finish formatting the graph, then add the mean that you calculated as a bar to the
graph. (*note: we will be adding more to the graph as you progress through the questions).

"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."

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

the question isn't complete here so i can't right an answer '_'
