The correct Answer is:
To solve the question, we need to fill in the blanks in the given statements based on our knowledge of human reproduction, specifically the male and female reproductive systems. Let's break down each statement step by step: ### Step 1: Fill in the first statement **Statement (A):** Seminiferous tubules produce `overset((i))"_____"` while Leydig's cells produce `overset((ii))"_____"`. - **Analysis:** - Seminiferous tubules are responsible for the production of male gametes. - Leydig's cells, located in the interstitial spaces of the testes, produce testosterone. - **Fill in the blanks:** - (i) **Spermatozoa** - (ii) **Testosterone** ### Step 2: Fill in the second statement **Statement (B):** In females, urethra is small and conducts `overset((iii))"_____"` while in males it conducts urine and `overset((iv))"_____"`. - **Analysis:** - The female urethra is shorter and primarily conducts urine. - In males, the urethra serves a dual purpose: it conducts urine and also carries sperm (as semen). - **Fill in the blanks:** - (iii) **Urine** - (iv) **Semen** ### Step 3: Fill in the third statement **Statement (C):** The process of formation of spermatozoa from spermatogonia is called `overset((v))"_____"` and the process of maturation of spermatids into spermatozoa is called `overset((vi))"_____"`. - **Analysis:** - The formation of spermatozoa from spermatogonia is known as spermatogenesis. - The maturation of spermatids into spermatozoa is called spermiogenesis. - **Fill in the blanks:** - (v) **Spermatogenesis** - (vi) **Spermiogenesis** ### Final Summary of Answers: - (i) **Spermatozoa** - (ii) **Testosterone** - (iii) **Urine** - (iv) **Semen** - (v) **Spermatogenesis** - (vi) **Spermiogenesis**
