The half life of Carbon 14 is 5730 years. By substituting the given figures to the formula x=I(1/2)^n where x is the amount of the remaining material, I is the initial amount and n is the quotient between the time elapsed and carbon 14's halflife. You will arise with the formula x=20(1/2)^1.745. You will get 5.97 mg.

B) I and II
Explanation:
Male reproductive system produce gametes in the testis which is the part of male reproductive system. Testis are two in number normally which compose of seminiferous tubules which have spermatogenic cell which are responsible for the production of spermatids with the help of sertoli cells present in the seminiferous tubules.After production of gametes the spermatid are delivered to the female reproductive system by copulating organ which in human is penis.the sperm 1st produces in the semeniferus tubules then transfer in to the rate testies ,epidydemis then vas deference and then urethra and then outside the body.
