Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
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.

Answer:
if we cross BB with bb none of the offspring will have blue eyes so the answer is <em><u>b 0%</u></em>
Explanation:
B. Sympatric evolution. is responsible to this. It's the process of evolving species from one shared ancestor in the same geographic region.
<u>Darwin believed that the desires of animals have nothing to do with how they evolve, and that changes in an organism during its life do not affect the evolution of the species.</u>
