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.

Ovaries
20. The production of female gametes - occurs in the ovaries
Estrogens

Second Meiotic Division
21. Caplike structure - derived from the Golgi apparatus - develops over the anterior half of the head -contains enzymes needed to penetrate the tough outer covering of the ovum
Acrosome
Hermaphrodites
Menstrual Cycle
Secondary Oocyte
22. Produced when each meiotic division -rapidly degenerate
Four Parts of Interphase
Polar Body
Cervix
Corpus Luteum
23. Comlex process involving the formation and fertilization of gametes and regulation of these processes by bot parents

Secondary Spermatocytes
Plant vs. Animal cells
26. Muscular chamber which is the site of fetal development
Oocytes
Uterus
Tubers
Ovaries
27. (In Prophase I) process where homologous chromosomes (chromosomes that code for the same traits - one inherited form each parent) come together and intertwine
Mature Ovum
hCG (human Chorionic Gonadotrophin)
Meiosis
Synapsis
28. Steroid hormones necessary for normal female maturation -stimulate the development of the female reproductive tract and contribute to the development of secondary sexual characteristics and sex drive -responsible for the thickening of the endometrium
