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
Lights in a big city or even a small town create light pollution, which makes it really hard to see the stars at night. If you put a telescope on a mountain far away, there would be a lot less light pollution. The sky would be much clearer and you could see many more stars
