Explanation:

Question 13

• Option A: Semen is stored in the seminal vesicles, not corpora cavernosa.
• Option B: Corpora cavernosa are two paired erectile tissues in the penis, which is their key distinguishing feature.
• Option C: Hormones are not released by corpora cavernosa.
• Option D: Seminal fluid is produced by glands like prostate, not corpora cavernosa.

Question 14

• Option A: Shedding of uterine lining is part of menstruation, done by the uterus, not ovaries.
• Option B: Ovaries are female gonads that produce ova (eggs) and hormones like estrogen and progesterone.
• Option C: Menstrual blood is not stored in ovaries.
• Option D: Ovaries do not protect the cervix.

Question 15

• Option A: Releasing eggs from follicles is done by luteinizing hormone (LH), not progesterone.
• Option B: Progesterone thickens the uterine lining (endometrium) to prepare it for implantation of a fertilized egg, i.e., for pregnancy.
• Option C: Progesterone has no role in red blood cell production.
• Option D: Progesterone does not thicken Fallopian tubes.
