D because trachea is the tube, bronchi is what splits into your lungs, bronchioles are what look like branches of the bronchi, and alveoli are the little air bags at the bottom of the smallest bronchioles.
According to the cross-bridge model of muscle contraction, the muscles stiffen after death because ATP cannot bind and directly release the myosin head from the actin filament.
<h3>What is myosin?</h3>
Myosin and actin are two essential proteins in muscle cells that interact during muscle contraction.
Adenosin Triphosphate (ATP) is a key high-energy molecule required during muscle contraction that binds to myosin and whose hydrolysis enables to produce movement.
In conclusion, according to the cross-bridge model of muscle contraction, the muscles stiffen after death because ATP cannot bind and directly release the myosin head from the actin filament.
