A segment of DNA molecule found only in the body cells of organism
Answer:
The correct answer will be- Transverse tubules
Explanation:
Transverse tubules are the tubular structure formed by the extension of the plasma membrane which innervates the cardiac and skeletal muscle cells. The T-tubules structure is structured between 20-40 nm and located at the junction of the I and A band.
The signals from the motor neurons once raches the motor endplate in muscles are carried into the muscles by these T-tubules which transmits the signals to muscle cells at very high speed. The T-tubules cause the release of the Calcium ions from the sarcoplasmic reticulum that cause contraction of the skeletal muscle.
Thus, Transverse tubules are the correct answer.

The Idea that Electrons are spread evenly throughout the atom. Rutherford disproved this by aiming charged alpha particles through a piece of gold foil. The result allowed for scientists to realize that there was a cloud of electrons surrounding the nucleus, rather than being evenly distributed throughout it.
