How is cardiac muscle similar to smooth muscle?

A. Both are striated

B. They share no similarities

C. They share no differences

D. Both have one central nucleus

D?

I think it may be C..

no it's D

It's A and B.

Sorry, A and D.

The correct answer is D. Both cardiac muscle and smooth muscle have one central nucleus.

To find the answer, you need to compare the characteristics of cardiac muscle and smooth muscle.

First, you should have prior knowledge about the characteristics of different types of muscle tissue. Cardiac muscle is a type of muscle tissue found only in the heart and is responsible for pumping blood. Smooth muscle, on the other hand, is found in the walls of hollow organs such as the intestines, blood vessels, and uterus.

Now, let's compare the characteristics mentioned in the answer choices to determine the similarity between cardiac muscle and smooth muscle:

A. Both are striated: Striated muscle refers to skeletal muscle, which is different from both cardiac and smooth muscles. Skeletal muscles have a striped appearance due to the arrangement of actin and myosin filaments. Therefore, this choice is incorrect, as neither cardiac nor smooth muscle are striated.

B. They share no similarities: This statement is incorrect. Cardiac and smooth muscles are both types of muscle tissue, so they do share some similarities.

C. They share no differences: This statement is incorrect. Cardiac and smooth muscles have several differences in terms of location, function, and structure.

D. Both have one central nucleus: This statement is correct. Both cardiac and smooth muscles have a single, centrally located nucleus in their cells. This is in contrast to skeletal muscle, which has multiple nuclei per cell.

Therefore, the correct answer is D.
