↓

The sarcomere shortens.

The neurotransmitter (ACh) from motor neurons signals a muscle fiber to depolarize. The depolarization (Na+) will trigger Ca++ release and will initiate contraction by binding to troponin. Myosin pulls the actin strands. ATP sustains the contraction.

What type of food properties do not allow harmful bacteria to multiply rapidly?
user100 [1]
<span>Foods that are highly acidic tend to inhibit bacteria growth. Many times, bacteria do not acclimate well to acidic environments, so having a food with a very low pH will help to make sure that the bacteria can't thrive in such an environment. Fruits and vegetables are good examples of these types of food.</span>
