Evaluating the accuracy of each pair. Acrosin correctly digests the corona radiata. It helps the sperm penetrate the egg, not directly digest it, suggesting a slight nuance in its role.
Sertoli cells are involved in nurturing the developing sperm cells and are influenced by FSH to produce inhibin, which then inhibits further FSH production. This pair is technically correct.
Capacitation refers to the physiological changes sperm undergo to gain the ability to fertilize an egg, primarily involving sperm motility and membrane fluidity changes, not changes in the zona pellucida.
Ovulatory phase is accurately associated with an LH surge.
What changes are observed in the uterus:
(i) Subsequent to the implantation of the zygote and
(ii) If an egg does not get fertilized?
Name the part performing the following functions in the human female reproductive system:
(i) Production of eggs
(ii) Site of fertilization
(iii) Site of implantation
(iv) Entry of the sperms
Why are testes in human males located outside the abdominal cavity in scrotum?
Select the option having correct matching of the organism given in Column I with the mode of reproduction in Column II: Column I {0.2cm}
The percentage error in the measurement of mass and velocity are 3% and 4% respectively. The percentage error in the measurement of kinetic energy is:
If \( L, M, N \) are the midpoints of the sides PQ, QR, and RP of triangle \( \Delta PQR \), then \( \overline{QM} + \overline{LN} + \overline{ML} + \overline{RN} - \overline{MN} - \overline{QL} = \):
