1) Well, models are vital to use by scientists, because that way they can represent visually and help other people understand the point they are trying to stress about their project. A simple example would be to use a Bohr model to represent a specific chemical, and along with that show how many protons or neutrons does it have.

2)In science a universal law is a statement by which a particular action or a phenomenon would occur ALWAYS in the same way, and will ALWAYS abide to what the law states, while a theory is a guess on what kind of pattern does a particular phenomenon or experiment abide by.

3)The SI units are units of the metric system, and are used everywhere in the world for specific measurements, the kilograms is used when measuring mass, the meters  is used when measuring length,  the liter is used when measuring a volume of a liquid, and finally the cubic meters or m3 are used when measuring the volume of a solid. and those are the standards as well.

Why are Scout, Jem, and Dill so afraid of Arthur “Boo” Radley at the beginning of the novel?
erik [133]
Hey Gary! :)

Your answer would NOT be A because Boo hasn't been out of his house in about 15 years, the children have never even seen him, so there is no way that he could threaten them.

It is B because :

Scout, Jem, and Dill are afraid of Boo because they hear some pretty bad stuff about him. They've heard that he stabbed his father with scissors, and Boo hasn't been out of the house for nearly 15 years. All of this makes Boo seem pretty scary.

So, your answer is B) They have heard rumors that he is dangerous.

It isn't C because Atticus actually tells them NOT to be scared of Boo, because Boo has never done anything wrong.

It isn't D because the children are in fact extremely scared of Boo.

So, once again, your answer is B) They have heard rumors that he is dangerous.

~Hope I helped, Gary!~

What is the relationship between freedom and responsibility?
Digiron [165]
My personal opinion:
Freedom is the ability to do whatever you want, but responsibility is knowing the limits of that power and being able to tell what things are moral and smart to do.
