An experiment is set up to determine if wheat grows better when it is planted by itself or together with clover. the setup involves 3 pans of each treatment. set-up a, b and c contain wheat alone. set-ups d, e and f contain clover and wheat planted together, in rows alternating one seed of each type. one hundred seeds are planted in each pan. all treatments contain the same type of soil, are planted in the same size of pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. use passage 1-1. constants in this experiment are:

The constants in this experiment are:

Number of planted seeds

Soil type

Pan size

Temperature

Amount of sunlight

Explanation:

Both treatments the only variable is the absence/presence of clover, so then the other parameters remain as constants due to these do not change their size or amount for both treatments.

"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."
