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

17. As in mitosis - the parent cell's chromosomes are replicated in the 2N number of sister chromatids
Interphase (Meiosis)

18. Formed due to cortical reaction -hard layer that surrounds the ovum cell membrane and prevents multiple fertilizations -Followed by the fusion of sperm nucleus and form a diploid zygote
Regeneration
Chromatin
Meristems
Fertilization membrane
19. Occurs in vertebrates that reproduce in water (fish and amphibians) -female lays eggs in water and male deposits sperm in the vicinity -lack of direct passage of sperm from male to female reduces chances of fertilization considerably

24. Multilayered sac of cells that contains - nourishes - and protects an immature ovum -produce estrogen
Cellular Division (Multicellular Organisms)
Meristems
Sporophyte
Follicle
25. 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
Flagellum

Telophase (Interphase)
26. 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
