Answer 1

Answer:

The middle primary germ layer is called mesoderm, which gives rise to a gelatinous material called mesenchyme, which then gives rise to different types of connective tissue such as bone, muscle, and blood.

Explanation:

The mesoderm is that intermediate germinative layer (also known as the intermediate embryonic leaf) of the three that have the embryos of tribal animals during the gastric or embryogenesis phase, the first stages of embryonic development.

From the mesoderm all types of connective tissue are formed, all types of muscle tissue, the skeleton, blood and lymphatic system, sexual organs, muscle mass, heart among others.
