Meiosis II will not occur in an oocyte unless it is fertilized.
A female has more oocytes before she is born than at any time during her life.
Which of these happens during pregnancy?
Estrogen and progesterone enhance the uterine contraction.
Follicle stimulation hormone is released in large quantities.
Progesterone is responsible for the development of mammary glands.
Progesterone level increase and estrogen level decreases at the end of pregnancy.
Select the correct sequence of animal developmental events.
fertilisation --> cleavage --> gastrula --> blastocyst
fertilisation --> cleavage --> blastocyst --> gastrula
fertilisation --> blastocyst --> cleavage --> gastrula

I = (b) II = (a) III = (c)
I = (c) II = (b) III = (a)

The following statements are true about the placenta EXCEPT…
It eliminates waste products from the fetus.
It has an endocrine function during pregnancy.
It exchanges blood between the fetus and its mother.
It prevents the diffusion of mother's hormones into the fetus.
Which diffuses from fetal blood to maternal blood in the placenta?

The posterior lobe of pituitary gland secretes the oxytocin hormone.
The anterior lobe of the pituitary gland secretes the prolactin hormone.
The release of the prostaglandins hormone from the placenta is increased.
The level of progesterone hormone in blood is higher than estrogen hormone.
Name the structure that secrete human chorionic gonadotropin hormone

Figure shows fertilisation in mammals.
What might happen if the cortical granules do not fuse with the plasma membrane of egg?
Exocytosis of the sperm acrosome cannot occur
Depolarisation of the egg plasma membrane will occur
Protein on the surface of the acrosomal cap cannot bind to the sperm-binding receptors
Fertilisation envelope does not form and leads to fertilisation of an egg by more than one sperm
Which of the following structures undergo meiosis during spermatogenesis?

II = Primary spermatocyte
III = Spermatogonium
I and II only
I and III only
II and III only

Which of the following about reproduction is TRUE?
Sexual reproduction gives rise to new individuals that are identical to their parents
Asexual reproduction in invertebrates involves only binary fission
Sexual reproduction produces genetic variation among the offspring
budding and regeneration are two types of sexual reproduction
Which of the following is true about fruit development after double fertilisation?
The diploid zygote develops into the cotyledon
The ovule develops into the fruit
The integuments develop into seed coat
The triploid nucleus develops into the embryo
Figure shows a cross section of an embryo sac in a flowering plant. In the embro sac, N is a nucleus, where K, L, and M are nuclei enclosed in their respective cells within the embryo sac.
Double fertilisation occurs when the male gamete nuclei fuse with the nuclei of

L and N
L and K
L and M

Zygote --> blastocyst --> morula --> embryo
Zygote --> embryo --> morula --> blastocyst
When does the secondary oocyte complete its second meiotic division?
When the corpus luteum degenerates
During ovulation
When it is penetrated by a sperm
While waiting for the arrival of sperm in the Fallopian tube
