Answer 2

Answer:

The term that can't be used interchangeably are MOTOR UNIT - MOTOR NEURON.

Explanation:

The terms listed in the options above can be used interchangeably because there is similarity that exists between them except Moto unit and Moto neuron.

- invivo : thus equally means in the body.

- muscle fibres: This means the living muscle cell.

- muscle tension: this can be used to replace the word muscle force.

Moto unit can't be used to replace the word Moto neuron because they have different meanings. Moto unit consists of skeletal muscle fibres and neurones which works together to coordinate muscle contraction while Moto neuron is a nerve cell located at the central nervous system that directly or indirectly controls the effector organs.
