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.

Male Urethra
20. Secretes estrogen and progesterone

Meristems
Gametophyte Generation
Female Sex Hormones
Gametes
25. (In Anaphase I) homologous pairs separate and are pulled to opposite poles of the cell -accounts for a fundamental Mendelian Law -each chromosome of paternal origin separates (or disjoins) from its homologue of maternal origin - and either chromosome
