Kate started by reviewing the different organs. She knew that ovaries produce the eggs (oocytes) and that her uterus was where a fetus would develop. However, she was not really sure how they connected to one another, or where fertilization might happen. Starting with an oocyte that has been released from an ovary, trace the pathway that oocyte would follow before being flushed through the vaginal canal during menstruation (if a fertilized egg does not implant).
a. Ampuls of uterine tube
b. Isthmus of the tube
c. Cervix
d. Funds of terus
e. Body of uterus
f. Infundibulum of uten tube
Answer:
Refer below path of oocyte from Ovary to Vagina. Once oocyte is released by ovary, it is carried by uterine tubes to uterus either as unfertilized or fertilized ovum depending on presence or absence of sperm
path of oocyte from Ovary to Vagina. Once oocyte is released by ovary, it is carried by uterine tubes to uterus either as unfertilized or fertilized ovum depending on presence or absence of sperm.
Oocytes are developing eggs (an immature ovum). Within a follicle, oocytes grow until they are fully developed. The outer layer of the ovaries contains these follicles. Many follicles start to form during each reproductive cycle.
Normally, only one oocyte will grow into an egg and leave its follicle per cycle. Ovulation is the term for this action.
All of a woman's oocytes are present when she is born. As aging, this amount naturally declines. The quality and genetic stability of the oocytes are also compromised by aging.

The generalization could the field biologist correctly make is that the pepper frog and bullfrog do not interbreed.
What do you mean by Habitat?Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection.
In this graph, it is clearly demonstrated that the particular species undergo breeding at a specific period of time during a year. The species of pepper frog breed in the month of April, while the species of the bullfrog breed in the month of July.
