Which of the following events is $NOT$ associated with ovulation in a human female?
A
Decrease in estradiol levels
B
Full development of Graafian follicle
C
Release of secondary oocyte
D
$LH$ surge
Solution
(A) Ovulation is the process of releasing a secondary oocyte from the Graafian follicle.
This process is triggered by a sharp increase in Luteinizing Hormone $(LH)$ levels,known as the $LH$ surge.
During the follicular phase,the developing Graafian follicle secretes increasing amounts of estrogen (estradiol).
As the follicle reaches maturity,the high levels of estradiol exert positive feedback on the anterior pituitary,leading to the $LH$ surge.
Therefore,a decrease in estradiol levels is not associated with ovulation; rather,a peak in estradiol levels is required to trigger the $LH$ surge.

In human females,meiosis-$II$ is not completed until $..........$.
A
Puberty
B
Fertilization
C
Uterine implantation
D
Birth
Solution
(B) In human females,the primary oocytes complete meiosis-$I$ to form secondary oocytes and a first polar body. The secondary oocyte then begins meiosis-$II$ but gets arrested at the metaphase-$II$ stage. This meiosis-$II$ is only completed if a sperm cell enters the secondary oocyte during the process of fertilization. Therefore,the completion of meiosis-$II$ is triggered by the entry of the sperm.

How is an ectopic pregnancy identified?
A
Pregnancy with genetic abnormalities
B
Implantation at a site other than the uterus
C
Implantation of a defective embryo in the uterus
D
Pregnancy termination due to hormonal irregularities
Solution
(B) An ectopic pregnancy occurs when a fertilized egg implants and grows outside the main cavity of the uterus.
Most ectopic pregnancies occur in a fallopian tube,which carries eggs from the ovaries to the uterus.
This type of pregnancy is not viable and can cause serious health complications for the mother if not treated promptly.
