In what ways does the "viscosity" of H₂O — as a property of H₂O — beneficial to life on Earth? {No answer choices given. WILL CO
butalik [34]

The viscosity of water is the thickness of water (it might also be considered the stickiness when talking about other fluids). Water has many properties, and the viscosity of water influences in many of them. We can take the surface tension of a liquid as an example. The more viscous a substance is, higher will the surface tension be and vice versa since there will be a higher and lower attraction between molecules respectively.


→ The surface tension of water is something really important since it contributes in many ways to the environment and if you think about it, if the water was a little less viscous, there wouldn't be water since the viscosity of water makes it resistant to evaporation to a certain degree.


Hope it helped,

9966 [12]

Answer:

The first stage of neural communication, <u>conduction</u>, is the movement of the signal within a single neuron. <u>Transmission</u> is the movement of a signal between neurons.

Explanation:

The neuron is the irreplaceable and highly specialized unit of the Nervous System, since it is the basic element in the conduction of the nerve impulse. The primary function of the neuron, conceived in its uniqueness, is to receive information and transmit it, once it has been processed.

The nerve impulse only spreads in one direction. When a neuron is stimulated, electrical changes originate that begin in the dendrites, pass through the neuronal body, and end in the axon, this is known as conduction. At the point where an axon and a dendrite are associated, it plays a very important role in the transmission of the impulse from one neuron to another and in the functioning and coordination of the nervous system in general, since the neurons do not act in isolation. The neurons are arranged in such a way that the axon endings of one are connected with the dendrites of the next neuron, but there is no physical contact itself, but a microscopic space that separates them, in addition there is a neurotransmitter substance that allows the flow of nerve impulse under those conditions, said substance is acetylcholine. These transmitting molecules diffuse through the synaptic cleft and chemically transfer the signal, from the axon of a neuron to the receptor neuron.
