Albumen covering eggs of frog swells and forms protective jelly after coming in contact with water.

Vedclass · Answer

(A) The correct statement is that the albumen covering the eggs of a frog swells and forms a protective jelly after coming in contact with water. This jelly layer provides protection against mechanical injury and predators,and also helps in maintaining the moisture content around the developing embryo. Option $B$ is incorrect because hyaluronidase is present in the acrosome of the sperm,not the egg. Option $C$ is incorrect because only the head and middle piece of the sperm enter the egg in mammals; the tail is usually left outside. Option $D$ is incorrect because toads,like most amphibians,typically require water for external fertilization.
