Answer: Nutrition
Explanation: Nutrients are the essential nourishments for growth and the maintenance of life.
<span>s that a single on off switch can control the whole cluster of functionally related genes; these genes are coordinately controlled (ex: when Ecoli must make tryptophan for itself because the nutrient medium lacks this amino acid all the enzymes for the metabolic pathway are synthesized at one time)</span>
Answer: B. The release of calcium ions causes myosin and actin to attach to each other. This statement best describes a cause and it's effects that occur during the process of muscle contraction.
Muscle contraction can be explained by sliding filament theory.
1. Activation of muscles: the motor nerve generates an impulse to transfer signals from neurons to neuromuscular junction. This stimulates sarcoplasmic reticulum to release calcium into the muscle cells.
2.Contraction of muscles: calcium in the muscle cells binds with troponin causes actin and myosin to bind. Actin and myosin in the muscle binds and contract by utilizing ATP as a source of energy.

Well i subtracted 450 by 140 and got 310
Then those ones make the most sense so
Hope this helps!
