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
I believe it’s the Carboxyl group but confirm online. Hope this helped :))
<span>The three groups of amphibians: Frogs, Salamanders, Caecilians are different when they reach adulthood. Frogs have four legs with strong hind legs and no tails. Salamanders have tails and four short, weak legs that cause them to walk instead of jump. Lastly, Cacilians have no legs and are burrowing animals.
Amphibians must live in moist environments because they loose water through their thin skin. They need to be near water to replenish the lost water. Also their skin helps them breathe and they can get oxygen from the water.</span>
Answer:
<em>The correct option is E) both its structure and its orientation within the lipid bilayer</em>
Explanation:
Computational simulations can be described as models of a particular system of nature which are studied by making simulations on the computer.
Computational simulations are generally very easy to understand as they very easily help us understand the structures of molecules which can otherwise not be seen by the naked eye. They also help us to locate a molecule in a particular place.
