Answer:
The answer to the question: Where does the stimulus occur in order to initiate an AP, would be, B: Dendrites.
Explanation:
When an impulse is to be generated and passed on as an action potential towards a corresponding neuronal cell, and a final affected organ, the neurons need first to be stimulated so that an action potential begins. This stimulus comes as a neurotransmitter released by other neurons near the one that will be stimulated. This neurotransmitter will bind to the receptors on the dendrites of the neuron to be stimulated and immediately this will cause the ion channels, gated and non-gated, to open and close so that an action potential can be initiated. The cell body then initiates the first action potential, and will in turn stimulate the axon to also start their own action potential, which will, like a domino effect, move down to the axon terminals. This process will be followed all along a neuronal circuit.
Answer:
The correct answer is D. resting phase
Explanation:
Diastole is the resting phase when relaxation of heart muscles takes after contraction(systole). In this phase blood from veins and coronary sinus comes into the auricles and ventricles because of the pressure in the heart is less than veins and opening of A-V valve.
When both auricles and ventricles are relaxed it is called joint diastole. Joint diastole is called complete cardiac diastole and is 0.4 sec long. After the joint diastole auricular systole occurs in which auricles are contracted and ventricles are still relaxed called ventricular diastole.
After the end of auricular systole ventricles contraction starts and auricular relaxation occurs called auricular diastole.

<h3>What are the limitations of respirator?</h3>
Full-face respirators are bulkier than half-masks and are frequently less pleasant to use. Full-face air purifying respirators cannot be utilized for all sorts of air contaminants because the type and capacity of the filters and cartridges used limit their use.
<h3>What is the capacity of SCBA?</h3>
SCBA Cylinders are available in five sizes to accommodate all <em>Self Contained Breathing Apparatus</em> (SCBA) and Emergency Escape Breathing Devices: 2L, 3L, 6.8L, 9L, and 10L. (EEBD).
The SCBA delivers compressed oxygen from the oxygen cylinder to the wearer via cylinder valves, pressure reducers, demand valves, and other components. The absorbing canister absorbs carbon dioxide from exhaled air, and the breathing bag resupplies oxygen.
