Question

Which of the following is a correct association of an animal germ layer with the tissues or organs to which it gives rise?

A. endoderm: linings of liver passageways and lung passageways
B. ectoderm: outer covering of digestive system
C. mesoderm: skin
D. endoderm: internal lining of blood vessels
E. mesoderm: central nervous system

Answer 1

The endoderm gives rise to the linings of liver passageways and lung passageways. The mesoderm gives rise to the central nervous system.

Step-by-step explanation:

The correct association of an animal germ layer with the tissues or organs to which it gives rise is:

A. endoderm: linings of liver passageways and lung passageways

E. mesoderm: central nervous system

These associations are based on the development of germ layers in embryonic development. The endoderm forms the linings of the digestive tract and respiratory tract, while the mesoderm gives rise to the central nervous system.
