Which biome is mainly known for is extremely dry weather and low precipitation?
The desert.

In a food web can there be more than one producer or consumer?
Yes.
100
If you put a south magnet and another south magnet what would happen?
They would repel.

True or False: In a parallel circuit if one light bulb went out all the other light bulbs would go out too.
False
200
In a cell what is the job of the mitochondria?
To make energy for the cell.
200
Name three facts about the tropical forest.
It is located near the equator, very warm throughout the year, and it receives a large amount of precipitation.
200
In a food chain how many producers are there?
One.
200
True or False: Opposites repel and likes attract.
False.
200
What kind of circuit would you want to have in your house and why?
A parallel circuit because is one light went out the others would stay lit.
300
Which cell has a cell wall, a plant cell or an animal cell?
A plant cell.
300

Give an example of a food chain.
EXAMPLE: Algae -> Small Fish -> Large fish -> Shark
300
What might affect a magnet's strength?
Heat, radiation, strong electrical currents in close proximity to the magnet, and other magnets in close proximity to the magnet.
300
In a circuit does it make a difference of the amount of resistors?
Yes because if you have more resistors and do not add to the voltage the resistors will not be as strong.
400
What does the vacuole do in a cell?
Stores food, water, and waste.
400
Name three animals you would find in a temperate forest.
Deer, squirrels, and foxes.
400
What is a food chain?
A feeding relationship of one line of producers and consumers.
400
Can magnets be powered by electricity? If so what are they called?
Yes, they are called electromagnets.
400
In a circuit, what happens if you increase the voltage?
The appliance will be stronger and/or you can add more appliances.
500
Name all the steps of the cell cycle in order.
Interphase, prophase, metaphase, anaphase, telephase, and cytokinisis.
500
About what percent of the water on earth is salt water?
97%.
500
Give an example of a food web.
EXAMPLE: The python eats the monkey, frog, rabbit, and opossum. The eagle eats the frog, rabbit, opossum, and the cocoa beans. The monkey eats the cocoa beans and the fig. The frog eats the grasshopper. The rabbit eats the grass and the fig. And the opossum eats the fig.
