when mendel crossed true breeding tall and short parent plants (producing first generation), what was produced? a. all the offspring were tall. b. half the offspring were tall, the other half were short. c. about 90 percent were tall, but the rest were short. d. all the offspring were short. e. the offspring were intermediate in height relative to the two parent plants.

A. All the offspring were tall.

Explanation:

The tall gene was dominant over the short gene, and therefore the offspring's genotype would be Tt (T representing the dominant tall gene, t representing the recessive short gene). This means the phenotype (visible trait) would be tall.

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.

"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."
