Question

Which of the following correctly describes the fate of the embryonic germ layers?

A. Ectoderm develops into the nervous system and skin.
B. Endoderm gives rise to muscles and connective tissues.
C. Mesoderm becomes the digestive tract.
D. All germ layers form the circulatory system.

Answer 1

The ectoderm develops into the nervous system and skin, the mesoderm into muscles and connective tissues, and the endoderm into the digestive tract and internal organs, making option A the correct answer.

Step-by-step explanation:

The fate of the embryonic germ layers can be correctly described as follows: Ectoderm develops into the nervous system and skin, mesoderm gives rise to muscles and connective tissues, and endoderm becomes the digestive tract and other internal organs. Therefore, the correct option that describes the fate of the embryonic germ layers is A: Ectoderm develops into the nervous system and skin. The other options provided are incorrect because the endoderm, not the mesoderm, gives rise to the digestive tract, and while the mesoderm does contribute to the circulatory system, it is not the only germ layer to do so.
