Answer 1

a) undergoes internal fertilization

Answer 2

Answer:

A Lizard is not similar to human beings, cow and cat because it is (b) Oviparous.

Step-by-step explanation:

A lizard (class: Reptilia) is not similar to human beings, cats, or Cows (Class: Mammalia) because lizards are Oviparours while Cat, Cow, and Human beings are viviparous.

• Oviparous means an animal that lays eggs for reproduction. This phenomenon accompanies in vitro fertilization.
• In vitro fertilization refers to fertilization that takes place outside the body of an organism.  Common examples are fish, frogs, etc.
• Viviparous animals give birth to  young babies. These involve the process of internal fertilization.  Common examples are humans, cats, etc.

(a) Most of the members of Class Reptilia and Class Mammalia undergo internal fertilization. Internal fertilization is the union of sperm and eggs inside the female body.

(d) External fertilization is the union of sperm and eggs outside the female body. external fertilization usually takes place in water, where synchrony is needed ie male and female both releases sperm and egg at the same time in the water.
