Answer:

20 amino acids.

Explanation:

Amino acids are the monomers that combine together to form a protein. Two main types of amino acids are non- essential amino acids and essential amino acids.

Thousands of different proteins can be made by the simple 20 amino acids present in the cell. The amino acids can combine in different ways to form all the proteins present in the body.

Thus, the correct answer is option (5).

Which diagrams shows reaction pathway that absorbs energy?

postnew [5]

Question:

<em>The diagram shows the potential energy changes for a reaction pathway.</em>

Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.

Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.

Answer:

Part 1: The diagram illustrates an endothermic reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.

Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.

Select the correct answer from each drop-down menu.

V125BC [204]

The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.

Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.

<h3>What are Skeletal muscles?</h3>

Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.

Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement. While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.

Therefore, it is well described above.
