The eggs of frogs do not have shells for protection, yet they are safe in water, how?

उत्तर
Frog’s eggs are without any external covering or shell but a layer of jelly hold the eggs together, thus providing them protection.
This jelly or gelatinous covering also protects them from drying up and prevents them from being eaten up by other animals or predators.
