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.

Monozygotic (identical) Twins
Sporophyte Generation
22. Near the end of telophase - the cytoplasm divides into two daughter cells - each wit a complete nucleus and its own set of organelles -In animal cells - a cleavage furrow forms - and the cell membrane indents along the equator of the cell and finally
Cytokinesis (Interphase)
Menstruation
Menses
Estrogens
23. Chromatin condenses into chromosomes - the spindle apparatus forms - and the nucleoli and nuclear membrane disappear
Spore Formation
Cytokinesis
Prophase I
Uterus
24. Cell undergoes a period of growth and replication of genetic material before the initiation of mitosis -cell spends at least 90% of life in interphase -each chromosome is replicated so that during division - a complete copy of the genome can be distr
Ovulation
