Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can

.
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.

24. Similar to mitosis in that a cell duplicates its chromosomes before undergoing the process -whereas mitosis preserves the diploid number of the cell - meiosis produces the haploid (1N) number - having the number of chromosomes
Follicle

25. The process by which gametes are produced -involves two divisions of primary sex cells resulting in four haploid cells called gametes
Chromatin
Secondary Oocyte
Menstrual Cycle

26. The spindle apparatus disappears. A nuclear membrane forms around each set of newly formed chromosomes. Thus - each nucleus contains the same number of chromosomes (the diploid number 2n) as the original or parent nucleus. The chromosomes uncoil - re
