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.

Disjunction
Asexual Reproduction in Plants
hCG (human Chorionic Gonadotrophin)
Monozygotic (identical) Twins
17. Can be fertilized during the 12-24hr after ovulation -occurs in the lateral - widest portion of the fallopian tube -sperm must travel through the vaginal canal - cervix - uterus - and into the fallopian tubes to reach the ovum

hCG (human Chorionic Gonadotrophin)
26. Homologous pairs (tetrads) align at the equatorial plane - and each pair attaches to a separate spindle fiber by its kinetochore
Disjunction
Fertilization/Conjugation
Vegetative Propagation
Metaphase I
27. Begins with the cessation of the menstrual flow from the previous cycle -FSH (Follicle Stimulating Hormone) from the anterior pituitary promotes the development of the follicle - which grows and begins secreting estrogen
Cytokinesis
Follicular phase
Embryo
Cellular Division (Multicellular Organisms)
28. The production of female gametes -occurs in the ovarian follicles
Oogenesis
Prophase (Interphase)
Flower
Fertilization
29. 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
Meisosis vs. Mitosis
Second Meiotic Division
Oogenesis
Asexual Reproduction
30. 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
