Which of these germinal layers give rise to the digestive system, the circulatory system, and the nervous system? . . endoderm, mesoderm, and ectoderm, respectively . . mesoderm, ectoderm, and endoderm, respectively . . ectoderm, endoderm, and mesoderm, respectively .

The correct answer is endoderm, mesoderm, and ectoderm respectively.

Explanation:

During gastrulation stage three-layered germinal layers forms in triploblastic animals. The three layers are known as - outer layer ectoderm, middle layer mesoderm, and the inner layer endoderm.

Later on, the digestive system rises from the endoderm, mesoderm rises to the circulatory system, and ectoderm differentiates to form the nervous system.

Thus the correct answer is Endoderm, mesoderm, and ectoderm respectively.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

option c is the correct answer.
