  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Animals giving birth to young ones are called viviparous animals. The egg of these animals typically contains less of yolk insufficient to support the development of the zygote into an embryo. Hence, development proceeds inside the body of the female animal and the fully developed embryo is delivered. Oviparous animals lay an egg. Their egg typically has more amount of yolk and can support the development of the zygote into an embryo. Ovovivipary is an in-between scenario in which eggs are retained till embryo is developed and is then delivered.

So, the correct answer is option B.

Mammals (except egg-laying mammals), like whale, shark, mouse, humans are examples of viviparous animals.

Birds that wade in water have

  1. Webbed feet

  2. Clawed feet

  3. Long legs

  4. Short legs
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Some birds, like cranes, wade in the water. They have long feet and toes. Along with long feet, they are also seen having long necks. As they move around in shallow waters, having long feet helps them in keeping their feathers high above the surface of the water. Thus they are kept dry and don't get wet with water even when the birds search for food inside water. This forms a part of their important adaptive behavior.

So, option C ''Long legs'" is the correct answer.
