They are found on the "rails" of the DNA. Meaning they are on the sides of the DNA ladder with the nucleotides as the "rungs."
The answer is; A
When an impulse from the motor neuron reached the neuromuscular junction, the voltage-dependent calcium channels are activated and the neurotransmitter released from the presynaptic cleft. When the neurotransmitter binds to their receptors on the sarcolemma, the muscle fibers become depolarised; the calcium is released from their vesicles. The Ca2+ ions are important in the power stroke because they bind to troponin. Upon binding calcium, troponin moves tropomyosin away from the myosin-binding sites on actin. Powered by the energy from ATP molecule, the myosin is able to bind on the actin and slides over the actin filament.
I think the correct answer from the choices listed above is option D. The most important reason to know basic first aid is that it<span> allows emergencies to be treated swiftly. This is because the things that should be done immediately when accidents happen are done and further accidents or complications are prevented.</span>
The acceleration would be the velocity at point O divided by the time of point O, also known as the slope at point O. (y/x)
