7. A nerve signal from the brain arrives at the intersection of the nerve and muscle cells and releases acetylcholine from the neuron. This triggers chemical changes in the muscle cell involving ions, including Ca2+. Calcium triggers the thick filaments, made of myosin, to attach to the thin filaments, made of actin, in the muscle cell, and the myosin pulls the actin toward the center of the muscle cell. ATP causes the release of the actin fibers, allowing the muscle to relax and the process to begin again.

Answer:
BB x BB
Explanation:
All of the offspring inherit traits from the dominant gene. This means there are no recessive present.
NADH and FADF2 are the reduced forms of the nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) coenzymes.
<h3>What is nicotinamnde adenine dinucleotide?</h3>
The nicotinamnde adenine dinucleotide (NAD) is a coenzyme used in the transport electron chain of the cellular respiration.
The movement of electrons is coupled to a proton gradient in order to generate ATP, the energy coin of the cell.
In conclusion, NADH and FADF2 are the reduced forms of the nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) coenzymes.
