PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You think that although there are some differences, the human nervous system is similar to a computer. You're friend says, "No way! A computer is just metal, wires, and plastic." Develop an argument that would persuade your friend that there are similarities between these two systems. Include specific examples and evidence to support your position.
Answer:
We have nerves that are just like wires that run through our body that tells us what is going on and what to do about it. The hard dive like in a computer is our brain, which is made up of three parts that control things like coordination, movement, involuntary, and voluntary movement. The sensory numerous just like the keys in a computer pick up what we are doing in life.

If the momentum of a car is reduced by half, assuming mass did not change, what must also have been reduced by half?
Answer:
Velocity is halved
Explanation:
Momentum is contingent on mass and velocity. The quantity of motion in a body is called the momentum of the body.
Momentum = mass x velocity
Now, if mass does not change and momentum is reduced by half, it suggests that the velocity was reduced by half.
Velocity is directly related to momentum.

Explanation:
A state property X has a value 89.6 units. It undergoes the following changes, first increase by
3.6 units, then increase by another 18.7 units, then decrease by 12.2 units and finally attains a
value of 85.5 units The value for this series of change is A) 14.2 units
B) -4.1 units C) 108.3 units
D) uncertain
Answer:
B) -4.1 units
Explanation:
According to this question, a state property X has a value 89.6 units. It undergoes the certain changes as follows:
- first increase by 3.6 units
- then increase by another 18.7 units
- then decrease by 12.2 units
- and finally attains a value of 85.5 units
This can be mathematically represented by 89.6 - {3.6 + 18.7 - 12.2 - x) = 85.5
To get x, we say;
89.6 + 3.6 = 93.2
93.2 + 18.7 = 111.9
111.9 - 12.2 = 99.7
99.7 - 85.5 = 14.2units.
The changes that occured is represented as follows:
= (3.6 + 18.7) - (12.2 + 14.2)
= 22.3 - 26.4
= -4.1 units
Loose sugar dissolves much faster than a sugar cube because loose sugar?
A. Has greater surface area
B. Has less kinetic energy
C. Has a higher temperature
D. Has greater surface tension
Loose sugar dissolves much faster than a sugar cube because loose sugar (a) has greater surface area.
When any solute dissolve in ground into small pieces it dissolve faster in solvent than large pieces because in small ones the large surface area is exposed into solvent.
With the greater surface area is exposer, the contact in between the solute particles and the solvent is more. this is the reason that loose sugar cube dissolve much faster than sugar cube as sugar cube has less surface area in contact with solvent.
Thus, Loose sugar dissolves much faster than a sugar cube because loose sugar (a) has greater surface area.

1. Why is soil erosion relatively less in dense forests as compared to barren, open fields?
Because the deep roots of big trees hold the soil and don't let it slip away simply by rain or wind.
Answer:
the roots of the trees keep the soil in place opposed to a barren landscape that has little to no plants to keep the soil in place

Answer:
formation process
Explanation:
farllon plate was fully subducted along pacific coast line
The cascade mountains formed from the igneous rocks by plate movement are younger and they are formed by the uplift of plates makes them appears aboveground in sierra Nevada.
What are cascade mountains in Sierra Nevada ?Since they were formed by melting above a subduction zone, the Cascades and Sierra Nevada's rocks are largely igneous. The Cascades, which initially arose 36 million years ago and are still forming now, are younger mountains.
In contrast, the Nevadan Orogeny, which occurred over 200 million years ago, is when the plutonic core of the Sierra Nevada started to form. When subducting at a sharp angle, oceanic lithosphere at the edge of the North American continent melted, and the magma surged back through the continental crust to form a volcanic arc.
The once-deep granite batholith that makes up today's Sierra Nevada was exposed by erosion after being raised by the North American plate. Although one small spur is located in Nevada, the elevated granitic intrusion is 640 kilometers long and largely located in California.

In lab you reacted 60 grams of propane (C3H8) with 13 grams of oxygen gas (O2). Your
reaction made 63 grams of water (H2O). The reaction is shown below:
How much carbon dioxide (CO2) is released into the air?
C3H8 + 5O2 ------> 3CO2 + 4H2O
10 g
73 g
120 g
1368
Answer:
120g
Explanation:
Based on the reaction, when 1 mole of propane and 5 moles of oxygen react, 3 moles of CO2 and 4 moles of H2O are produced. The ratio of production is 3 moles of CO2 per 4 moles of H2O.
Thus, we need to convert mass of water to moles using its molar mass:
Moles H2O (Molar mass: 18g/mol):
63g H2O * (1mol / 18g) = 3.5 moles H2O
Converting to moles of CO2:
3.5 moles H2O * (3 moles CO2 / 4 moles H2O) = 2.625 moles CO2
Mass CO2 (Molar mass: 44g/mol):
2.625 moles CO2 * (44g / mol) = 115.5g of CO2 are released

What is the total number of atoms in 0.20 mol of propanone, CH3COCH3?
NA = 6.022 x 1023
1.2 x 1022
1.2 x 1023
6.0 X 1024
6.0 x 1023
Answer:
1.2×10²³ atoms.
Explanation:
Data obtained from the question include:
Mole of propanone = 0.20 mole
Number of atoms of propanone =.?
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.022×10²³ atoms.
This implies that 1 mole of propanone also contains 6.022×10²³ atoms.
Thus, we can obtain the number of atoms in 0.20 mole of propanone as illustrated below:
1 mole of propanone contains 6.022×10²³ atoms.
Therefore, 0.20 mole of propanone will contain = 0.2 × 6.022×10²³ = 1.2×10²³ atoms.
Thus, 0.20 mole of propanone contain
1.2×10²³ atoms.
The total number of atoms in 0.20 mole of propanone is 1.2×10²³, i.e. in given mole 1.2×10²³ atoms of propanone is present.
How many atoms present in one mole?In one mole of any substance 6.022 × 10²³ atoms of that substance will present, and this number is known by the name of Avogadro's number.
We have given moles of propanone = 0.20 mole
No. of atoms present in 0.20 mole of propanone = 0.20 × 6.022×10²³ = 1.2×10²³.
Hence, 1.2×10²³ atoms are present in given moles.
