In males which of the following organ performs a dual function of ejaculation of sperm and voiding of urine

Urethra

Explanation:

The urethra is a tube like structure which performs the function of excretion as well as copulation. It carries the urine stored inside the bladder to the outside the body. During copulation, the semen is ejected from the urethra inside the female external genitalia that is vaginal canal. The urethra prevents the flow of urine and it just allows the ejaculation of semen during copulation.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
