Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers
Given what we know, two common medical or biological conditions that may create a hazardous environment when working in a microbiology lab are asthma and working with an infectious disease that may become airborne.
<h3>Why would these conditions prove hazardous?</h3>
- Working with chemicals and microbes can be especially hazardous to individuals with asthma.
- This is due to the strong effect that certain chemicals can have in triggering an asthma attack.
- Microbes may also cause upper respiratory tract infections if breathed in, further worsening asthma.
- Likewise, working with an infectious disease that has the capability to be airborne is especially hazardous given the ease with which one may become infected and transmit the disease.
Therefore, we can confirm that two common medical or biological conditions that may create a hazardous environment when working in a microbiology lab are asthma and working with an infectious disease that may become airborne.
