When an external stimulus crosses the threshold, a muscle fibre will respond.
<h3>The level of the threshold</h3>
- For the identification of the electrical activity carried out by the active muscles, the threshold level is a crucial consideration.
- A portion of the electrical activity carried out by the target muscles may be excluded if the chosen threshold level is higher than the overall activity.
<h3>What is the stimulus threshold for muscle contraction?</h3>
- A certain stimulus magnitude is necessary for muscle contraction.
- The threshold stimulus is the smallest amount of force needed for a stimulus to cause a muscle to contract in response.
- If the stimulus intensity is less than this threshold value, there is no response.

The branch of biology that deals with the relations of organisms to one another and to their physical surroundings.
<span>The connective tissue membranes that are found lining the joint cavities are called the synovial membranes. Joint cavities, like the shoulders, elbows, or knees, are known as freely movable joints. The synovial membranes line joint cavities that are not open to the outside.</span>
Answer:
By bonding with each other.
Explanation:
Larger macromolecules are formed from smaller macromolecules by making bonds with each other. carbohydrate is a macromolecule which is formed from glucose which is a micromolecule. Proteins is also a macromolecule composed from amino acids while lipid is also a macromolecule that are formed from fatty acids. These small micromolecules join together forming covalent bonds with each other.
The independent variable controls the dependent variables.
