Answer:
1) Make an observation.
2) Ask a question.
3) Form a hypothesis, or testable explanation.
4) Make a prediction based on the hypothesis.
5) Test the prediction.
6) Use the results to make new hypotheses or predictions.
Explanation:
The individual bacteria would appear larger under the magnification of 40X. Thus, the correct option is A.
<h3>What is Magnification?</h3>
Magnification may be defined as the power of a microscope to deliver an image of an entity at a scale larger and sometimes smaller than its genuine size.
Bacillus subtilis is a distinct germ, that is rod-shaped in structure and is Gram-positive. Under the 40X microscope, it looks as rough, opaque, fuzzy white, or narrowly yellow with irregular edges.
The size of the entity or any object under the microscope of 40X magnification is 5mm, while the of the entity or any object under the microscope of 10X magnification is 1-2mm.
Therefore, it is well described above.

When sarcomeres shorten, the muscle fiber SHORTENS.
Mechanism :
Sacromeres are used to construct the myofibrils, which are a part of the skeletal muscles of animals. They use the sliding filament model to carry out the muscle contraction and relaxation.
To create movement, The cross-bridge between actin and the myosin heads causes the sacromere to shorten. Muscle fibers contract as a result of this shortening of the sacromere, which has the overall effect of shortening the fibers.
