Question #1

One kind of neuron would be known to be called a "<span>Sensory Neuron". This kind of neuron would be a kind that would send messages to your 5 senses. Which, when speaking about a human, this would therefore be our eyes, mouth, hearing, feel, and smell. This kind of neuron would send direct messages.

For example: My mother is cooking 'good o' brownies" in the kitchen. My "sensory neuron" would then smell these brownies, and then as I would smell it, I would then understand what is cooking. Therefore, this would then be an example of what this kind of neuron would then do.

(second neuron)

Now when speaking about a "motor neuron", this kind would then be the kind that would send the information OUT of the nerve system, not going INSIDE of the system, but it would be going outside of the body. And as this information would then leave and then go into the muscle or also the glands of the nerve system.

Question #2

</span><span>Which type of neuron is activated when you spontaneously withdraw your hand when it touches something hot?
</span>
This kind of neuron would be the kind neuron that would be known to be called "sensory neuron".

Let's consider: We would have to remember, sensory would be how you would feel, your sense on matter. And in this case, this person would be feeling her senses as she would be (touching something hot). And therefore, this would be known to be a "sensory neuron".

What are the 3 laws of motion?
laiz [17]

Answer:

1.Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

2.The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma.

3.For every action there is an equal and opposite reaction.

Hope this Helps!

Describe how you would separate rock salt to obtain salt crystals and pure dry sand.
USPshnik [31]

Answer:

Separating Sand and Salt

Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.

Answer Quickly : Define and compare boiling points, melting points, and freezing points.
juin [17]
Boiling point is the temperature at which a substance begins to change to a gas. Melting point is the temperature at which a substance begins to turn into a liquid. And freezing point is the temperature at which a substance begins turning into a solid.

What is the lower concentration limit (vol%) at which a mixture of ethanol in air can explode?
liubo4ka [24]

Answer:

Lower explosive limit (LEL) of ethanol = 3.3%

Explanation:

In the case of alcohol, ethanol presents certain fire hazards. Its momentary flash point is 55ºF (12.9ºC), while the momentary flash point of gasoline is -45ºF (-42.8ºC), and the E85 mixture ranges between -20ºF and -4ºF (between -28 , 9ºC and -20ºC), and has a wider range of flammability limits than gasoline. For emergency response teams, this implies that during a release of the typical ethanol / gasoline mixture, the fuel can be expected to behave like gasoline: It is heavier than air - as we mentioned earlier - and can produce vapors and form flammable mixtures in the air, under most environmental conditions.

General properties and comparison with other inflambles products:

Flash point momentary Gasoline = -45 ° F

<u>Ethanol</u> = 55 ° F

E 85 = between -20º and -4º F

<u>Flammability limits </u>

Lower explosive limit (LEL) of ethanol = 3.3%

Upper Explosive Limit (UEL) = 19%

Lower explosive limit (LEL) of the mixture E 85 = 1.4%

Upper Explosive Limit (UEL) 85 = 19%

Lower explosive limit (LEL) of gasoline = 1.4%

Upper Explosive Limit (UEL) = 7.6%

They have a wider range than gasoline
