Answer:

Many people link nicotine to cancer, especially lung cancer. Nicotine is one of many chemicals in raw tobacco leaves. It survives the manufacturing processes that produce cigarettes, cigars, and snuff. It is the addictive element in all forms of tobacco.

Researchers are looking at how nicotine contributes to the development of cancer. While it may be too early to say nicotine causes cancer, questions are being raised about how the chemical acts in non-tobacco forms like e-cigarettes and nicotine-replacement patches. Researchers are discovering that the connection between nicotine and cancer is more complicated than commonly thought.cancer-causing effects:

A muscle fiber is a group of motor units. true false
amid [387]

The right answer is False. (An important element missing from the definition of motor unit are motor neurons.)

A motor unit is composed of an alpha motor neuron and the muscle fibers it innervates.

Groups of motor units often work together to coordinate the contractions of a single muscle. All motor units that serve the same muscle are considered to be a group of motor units. The number of muscle fibers connected to each unit can vary: the muscles of the thigh can have up to a thousand fibers per unit, the muscles of the eyes can have only ten. In general, the number of muscle fibers involved in a motor unit is a function of the muscle's need for its refined movement: the more the muscle will need a fine movement, the less the motor unit will involve synapses with the muscle fibers.
