		gastrulation.
		organogenesis.
		embryonic folding.
		ingression

2.What component allows semen to temporarily coagulate, preventing it from leaking back out of the female reproductive tract, once ejaculated?

		clotting proteins and enzymes
		alkaline pH
		antimicrobial chemicals
		fructose

3.

Which of the following is NOT a function of amniotic fluid?

		allows the embryo freedom of movement
		protects the embryo from trauma
		maintains a constant temperature for the developing embryo
		provides nutrition for the developing embryo

Answer 1

1) The differentiation of the germ layers into organs and organ systems is known as gastrulation . The process of formation is called as organogenesis

2) Clotting proteins and enzymes are the components of the semen to temporarily coagulate, preventing it from leaking back out of the female reproductive tract, once it is ejaculated

3) Amniotic fluid doesn't provide nutrition to the developing embryo . Nutrition is provided by yolk sac and placenta

Amniotic fluid provides free movement to embryo , provides protection against external trauma and provide constant temperature
