Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury. Different cells grow and die at different rates. Some cells, such as epithelial<span>epithelialA thin layer of epithelial cells that makes up the outer surfaces of the body (the skin) and lines hollow organs, glands and all passages of the respiratory, digestive, reproductive and urinary systems.</span> cells, reproduce quickly. Other cells, like nerve cells, grow slowly. Both normal cells and cancer cells go through a sequence of steps, or phases, when they form new cells. This is called the cell cycle.

Answer:
When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the dependent variable is the number of shirts made by the employee.
Explanation:
In a study or research, the dependent variable is the result of the intervention on the independent variable, which can be modified. In the case presented, the dependent variable is the quantity of shirts made by the employees, the number of which is measured at the end of the study.
It is expected that those employees who block the noise using headphones produce a greater number of shirts than those exposed totally or partially to noise.
For the other options:
- <u><em>The amount of noise</em></u><em>. This can modified by the use or not of headphones and is the independent variable, subject to modification.</em>
- <u><em>The type of music the employees listen to while they work</em></u><em>. Does not represent dependent or independent variable.</em>
- <u><em>The amount of training employees need</em></u><em>. It is not the variable being studied.</em>

Myocardium, that's because myocardium simply means 'muscular tissue of the heart'. It is not pericardium or connective tissue as these are only small, specific areas of the heart and a heart attack can cause cells to die anywhere in the heart.
