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.

Accurately 2 different ways that antiretroviral drugs can prevent virus formation
Nataliya [291]

Answer:

Two different ways in which antiretroviral drugs can prevent the formation of new viruses are:

  1. Inhibiting the reverse transcriptase enzyme in both nucleoside analogues and non-nucleoside analogues.
  2. Enzymatic inhibition of integrase enzymes.

Explanation:

Antiretroviral drugs are those used for the treatment of human immunodeficiency virus (HIV) infection, making the effect of the virus on the host cell is less and preventing the development of AIDS.

This type of drug has been classified, according to their mechanism of action, being grouped into several families of drugs. Two different ways by which antiretroviral drugs can prevent the formation of virus are:

  1. <em><u>Inhibition of reverse transcriptase enzyme</u></em><em>: this enzyme is a DNA polymerase capable of forming single strand viral RNA by a process that is reverse to normal DNA to RNA transcription. Its inhibition prevents the formation of viral particles in the host cell. They are divided into nucleoside analogs and non-nucleoside analogs.</em>
  2. <em><u>Enzymatic Inhibition of Integrase enzymes</u></em><em>: this type of enzyme is contained in the virus, and is capable of causing a retrotranscribed DNA to integrate into the host cell's DNA so that viral replication occurs. Its inhibition prevents the replication process.</em>

The most effective treatments against HIV infection involve the use of two or more types of antiretroviral drugs.
