.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

Menses
Prophase (Interphase)
Meisosis vs. Mitosis
Telophase I
25. Occurs midway through the cycle -a mature ovarian follicle bursts and releases an ovum -caused by a surge in LH (Luteinizing Hormone) that is preceded - and in part caused - by a peak in estrogen levels
