Answer:
The correct option is B.
Explanation:
Muscle tissues of the heart refers to a group of cells that are carrying out similar functions in the heart. There are three different types of muscles, these are skeletal, cardiac and smooth muscles. The cardiac muscles are found in the heart, they form the contractile wall of the heart. These muscle contract involuntarily ( that is, without any external stimulation) and they are single nucleus, striated and short.
Answer:
The correct answer is B. Single-nucleus, striated, branching cells.
Explanation:
This is because the heart has to communicate with itself, and to do that, it has to have branching cells. In addition, the heart has to continue pumping all of the time for many years, so the structure has to be thick and sturdy.
Hope this helps!
