Does Temperature play and role in condensation.If not why not.If yes.Why
Temperature does play a role in condensation.That role is when the temperature is colder then particles lose kinetic energy and start slowing down and don't bump into other particles.When temperature are more hotter then particles have more kinetic energy and start bumping into more particles.
Elements that are not synthetically prepared came from people discovering them and named after them.True or False.
False.
The elements actually came from the explosion from the Big Bang sending all elements throughout our gigantic universe.
Who was the first explorer to reach India and to allow Portuguese to take a leading position in India's rich spice trade.

Solve this two step inequality
2/3>-4y-8 1/3
Step 1.Add 8 1/3 to both sides
2/3+25/3>-4y
Step 2.Simplify the left side
9>-4y
Step 3.Divide -4 by both sides.Make sure change the inequality sign.
y>-9/4
The answer to this inequality is y>-9/4
Why does when a cyclone in the northern hemisphere spin one way but a cyclone in the southern hemisphere spin the other way.
The Coriolis effect.
The Earth is a sphere and is wider in the middle that is why when it spins on it's axis the equator spins faster.
When France gifted the US the Statue of Liberty it was copper brown now why is it green now?
It is now green because of the chemical reactions it reacted with our atmosphere including the air and water around it producing copper carbonate which is the green coating.
Who were the first people to settle in America and why did they come here and settle.
The first people to come here was the English/British.They came here because they didn't like England's new form of government.
What do vascular plants and multicellular animals have in common to transport nutrients.
Multicellular animals and vascular plants have specialized structures to transport nutrients and both plants and animals nutrients flow through a system of vessels are things they have in common to transport nutrients.
Focus:The Midpoint Formula
Draw a coordinate plane on a piece of paper.
Put points on coordinates (3.-4) and (6,1) and draw a line from both points.Find the middle coordinates from both points
Step 1.Take the average of both x and y coordinates
X coordinate average:3+6/2=4.5
Y coordinate average:-4+1/2=-1.5
So the middle point between the two coordinates are (4.5,-1,5)
If humans and objects are opague then why can see other objects and things as they are?
You can also reflect light like mirrors actually every object can reflect light like tables,water bottles,and books not just mirrors.But there is something different.When light reflects of mirrors the reflection comes back in one's eyes in one angle.When other objects besides mirrors are being hit by light the reflections get scattered into many angles from a plane surface.That is why when light reflects off mirrors it is called regular reflection and when it reflect off other objects it is callled irregular reflection.
Say you have a wet shirt and you put it out in the sun to dry.Then you check a half hour later and you're like this was fast.Why do you think the shirt took only a half hour.
So the Sun rays are going to hit water molecules that are on the shirt which are called photons now the molecules have kinetic energy to escape the shirt and evaporate into the air.
What was the period known when there was a shift from making goods by hand to making them in a factory.
The Industrial Revolution
The Industrial Revolution came because mass production was a key part at the time.Mass production is when you use the idea of interchangeable parts or parts that are the exact same size and shape to make many goods at the same time.
What was the special organism that made animals plant humans people and what is known today as life?
The Eukaryotes
A theory of how Eukaryotes caused life was when Eukaryotes ate other Eukaryotes they didn't digest them and they just stayed their and so when more and more Eukaryotes were eating other Eukaryotes it started a more complex organism of what we called multicellular organism like us humans.
Simplify this equation
(x3+3x-6)+(-2x2+x-2)-(3x-4)
Step 1.Make a huge equation
x3+3x-6-2x2+x-2-3x+4
Step 2.Take like terms and simplify
x3-2x2+x-4.
The answer is x3-2x2+x-4
If you have two objects a wool cloth and a copper bowl .Why is one a bad conductor of heat and why is one a good conductor of heat
This is because wool might some holes or spaces that particles could go through that is why it has less resistance.But for the copper bowl it is more enclosed so that heat particles cannot get out. That is why it has more resistance and a good conductor of heat.
Say you have a cup filled with copper sulfate.You keep adding teaspoons and teaspoons of it.Then you see after a period of time of time the sulfate won't dissolve.
Why is this?
This is because the water in the cup can't hold any more of the solvent/copper sulfate.
This mixture is too saturated and if you add any more of the copper sulfate then the mixture results in a solid precipitate or is left off as a gas.
When Washington was president two members of his cabinet Alexander Hamilton and Thomas Jefferson had many disagreements.Hamilton believed the country should be based on trade and industry while Jefferson believed the country should be based on farming.Hamilton followers were called Federalists and Jefferson followers were called Democratic Republican.What side would Northerners and Southerners be on and what type of people and why
Southerners would support Jefferson because there are more farmers working on their plantations in the South.Northerners would support Hamilton because they had many factories up their and merchants would be selling and trading goods.
What are the two factors that show your phenotype that you have.
The two factors are the combination of the genotype that you have and the enviromental factors outside.
The combination of the genotype meaning the genetic information that you carry and each trait in you has two parts.An allele one from your mom and one from your dad.The enviromental factors are like if you play in the sun for too long then your skin color might become darker.

When we pluck a guitar string why do we hear sound coming from it?
We hear sound because when we pluck the guitar string we are compressing air molecules so that the molecules become more compact and so the molecules start hitting each other and that what makes the sound and when it comes back it becomes less compact and so molecules have to use more energy to make sound and so it is going from a region of high pressure to low pressure.Sound is not just compressing molecules in a straight line.It is starting to get the ratifactored in all possible directions.
Neutrons are in the ____ of an atom.
A neutron has a _____ charge.
Fill in the blank
Nucleus,Electrically Nuetral
A Nuetron is a subatomic particles which are found inside the nucleus of an atom.They have a neutral charge unlike protons(positive charge) or electrons(negative charge).So say if you had an element like Carbon with the same number of protons and electrons then the atom has a neutral charge

What are the two parts of your body inside you that defend you from viruses and bacteria?
The Skin and Mucous Membranes
You might think your skin is just to occupy our organs and organ systems inside but the main purpose of our skin is too defend.It is hard to penetrate,oily,and acidic.The Mucous Membranes line up all the membranes of all the organs like nose respiratory track and many more.The mucous membranes secretes a sticky fluid called mucous which traps the bacteria and virus with it to try to get it out of your body.
