which of the following is true about the germ layers of animals formed during embryogenesis? choose all that apply.
the ectoderm layer grows into tissues on the outer layer of the body, such as skin or hair
in frogs, the mesoderm layer forms from cells entering the blastocoel from the outside of the blastula
the endoderm layer will become the digestive and respiratory systems
the three tissue layers are formed after the process of neurulation.

Explanation:

1. The ectoderm gives rise to outer - layer tissues like skin and hair.
2. In frogs, mesoderm forms from cells entering the blastocoel from the outside of the blastula.
3. The endoderm develops into the digestive and respiratory systems. Neurulation occurs after the formation of the three germ layers.
