17. a botanist discovers a new species of plant in a tropical rain forest. after observing its anatomy and life cycle, he notes the following characteristics: flagellated sperm, xylem, separate gametophyte and sporophyte generations with the sporophyte dominant, and no seeds. this plant is probably most closely related to

The correct answer will be- Pteridophytes

Explanation:

The plant kingdom is divided into many divisions which are distinguished on the basis of unique characteristics present in them. The main plant groups are Thallophytes, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.

The plant group which is characterised by having dominant sporophyte, no seeds, presence of xylem and the flagellated sperms is known as the Pteridophytes.

The pteridophytes are the vascular plants with no seed production and contain flagellated sperm which help the sperm to swim to reach the female reproductive structure.

Thus, pteridophytes are the correct answer.

they have sperm in my gf's mouth

explanation:

"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."
