Answer:A motor neuron only innervates one muscle fiber.

Explanation:

One motor neuron can innervate several muscle fibres.

The combination of one motor neuron innervating several muscle fibre is called a motor unit.

The number of  skeletal muscle fibres innervated is called the innervation ratio.

Group of  the motor unit works together to coordinate contraction is a single muscle cell.

Motor neurons transmit impulses from the spinal cord to skeletal and smooth muscles. They form rod-shaped clusters that run parallel to the axis of the cord for spinal cord segments.

Psychology:
antoniya [11.8K]

Answer:

My answers are all opinionated responses so feel free to use it as a guideline for your own answers to these questions.

Explanation:

  1. If you begin crying or wanting to cry, you are likely sad. If you give up on doing things such as passing on activities you would normally jump at, you are likely sad. If you want to punch something or hurt someone, you are likely angry. If your body becomes hot, you are likely angry. If you become aggressive or want to become aggressive, you are likely angry.
  2. You feel stress on many occasions, but a typical stressful response is when you are dealing with something that will affect you in the near or far future. For example, worry of failing a test can be stressful as it will affect your near future whether it be parents punishing you or having to retake the class entirely. Something that requires a lot of effort yet has risk is also stressful. For instance, investing your life savings or even just a chunk of your hard earned money may stress you because you fear the near and far future consequences - losing all of your money.
  3. There is no actual psychology category on Brainly so I would say psychology fits best under the health category (especially this question) because psychology refers to the mental state (or health) of beings. Technically, it can also count as a science as psychology is a scientific study with many scientific experiments included within the class. My advice is to use your best judgement in determining which category fits best for your psychology question.
