Is Water Wet? If So, What makes it wet, if not what makes it dry?
Monica [59]

Answer:

Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.

Explanation:

For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.

When you put water onto water, it's an addition of water, you don't say it's wet or wetter.

Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.

Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.

So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.

Systems that use massively parallel systems of processors whose architecture is based on the human neuron structure are called
sashaice [31]

Answer:

Neural networks

Explanation:

The neuron is the structural and functional unit of the nervous system. The neuron is also known as a nerve cell. The neuron is the largest cell of the body that helps to communicate or transmit signals. A neuron has an axon body, dendrites, and terminal region. The transmission of the signal from one neuron to another through the axon terminal.   Large numbers of neurons are present in the human body system that coordinates the whole body system. Neural networks contain a massive amount of neurons whose architecture is based on neurons. So, the correct answer to the given question is neural networks that use massively parallel systems based on neurons.
