C) Prevent the embryo from drying out

PLEASE HELP!!!

Respuesta :

Answer:  The correct answer is -C) Prevent the embryo from drying out.

The amniotic egg of birds and  reptiles is surrounded by an outer, tough, and protective shell, which protects the egg from any damage, predators, pathogens, and drying out.

The tough shell and extra embryonic membranes create a safe environment where an embryo can develop into a whole organism (with different organs like eyes ,ears, brain, kidney, heart).

Thus, option C) is the right answer.

The correct answer is option C.

Eggs with tough protective shells developed to prevent the embryo from drying out.

The hard shell of the egg is made of calcium carbonate and it protects the embryo from predators and from drying out. The egg shell is porous which allows air and moisture to pass through its pores.
