Question

Choose the correct answers from the alternatives given.
The presence of mesoderm

• A. restricts the development of a coelom
• B. is associated with the organ level of organization
• C. is associated with the development of muscles
• D. both (b) and (c)

Answer 1

The correct option is D both (b) and (c)

.The mesoderm gives rise to bones, muscles, the heart and circulatory system. Also, due to the evolution of the mesoderm, triploblastic animals develop visceral organs such as stomachs and intestines, rather than retaining the open digestive cavity characteristic of diploblastic animals. So, the mesoderm helps in the development of the organs and is associated with the organ level of organisation.

So the correct option is 'both (b) and (c)'.
