Opiates are medications that can be used as painkillers. These are derived from the opium. Opiates reduce pain as they act as CNS (central nervous system) depressants. The CNS is also associated with regulation of heart beat and respiration. Thus, the opiates also slow down the respiration by slow down the CNS.
Hence, the correct answer is 'opiates.'
Administration of basic life support is necessary when put in htis scenario.
The first thing to do is to open the airway with the head-tilt/chin-lift maneuver, look-listen-feel for breathing, and if the child is not breathing normally give 2 rescue breathes.
membrane potential, neurotransmitters, electrical signals
electrical signals, all or none, neurotransmitters
all or none, membrane potential, electrical signals
All or none, membrane potential, electrical signals is list of words describes an action potential. Option 4 is correct.
An action potential is a rapid change in the electrical potential of a cell membrane. It is a wave of depolarization that travels down the axon of a neuron. Action potentials are "all or none" events. This means that they either occur fully or not at all.
Action potentials are triggered by changes in the membrane potential. The membrane potential is the difference in electrical charge between the inside and outside of the cell membrane. When the membrane potential reaches a certain threshold, an action potential is triggered. This threshold is called the refractory period.
Once an action potential is triggered, it travels down the axon of the neuron. The action potential causes the release of neurotransmitters at the synapse. Neurotransmitters are chemicals that allow neurons to communicate with each other. They bind to receptors on the next neuron, which can trigger another action potential. Option 4 is correct.

Answer is Communicable disease can be spread by inanimate objects, such as doorknobs.
The causal organisms of some of the communicable diseases are bacteria and viruses. The communicable diseases such as common cough and cold can be transmitted to a healthy person by indirect contact with contaminated substances such as food, air, soil, feces, equipment, objects including doorknobs, remote controller, etc.
