Document Summary

The reason they don"t fly around space they"re attracted to positive charges atoms. Atoms will participate in any amount of chemical bonds to get full. 8 is full in the outer shell of atom. It doesn"t need to react if they are full. How many chemical bonds an atom forms determines how many electrons they have in the outer shell. Hinderburg exploded in 1937 because hydrogen wasn"t inert and it formed chemical very easy anytime something forms a bond with oxygen (combustion). If an atom has a vacancy in the outer electron shells, it will try to fill that vacancy or get rid of the extra electrons so the outer shell is full. In order for charge to be 0 it has to have same number of protons as electrons. A chemical bond is an attraction between too atoms. Don"t get transferred back and forth they are just shared. Anytime you have a chemical bond you have a molecule.

Why does sodium react so easily with chloride to make sodium chloride?

	A.	Both atoms have incomplete outer orbitals and they complete each other's when they combine
	B.	Sodium chloride is table salt, one of the most reactive molecules in living things.
	C.	Opposites attract.
	D.	Both atoms have outermost shells full of electrons.
	E.	Sodium chloride is highly explosive.

What is meant by the statement âlife is diverse?â

	B.	Each living thing is a unique individual.
	C.	All living things are related to each other.
	D.	There are many different kinds of living organisms on Earth

	A.	DNA
	B.	Carbohydrates
	C.	A molecule
	D.	Nucleic acid

In evolution, why is it important that individuals vary from each other?

	A.	Variation allows some individuals to do better than others, so those variations are selected for.
	B.	If variations or mutations are extreme enough, new species can result.
	C.	Variations are important because individuals have to change through time.
	D.	Variations are important because they're inherited.
	E.	Variation gives every individual an equal chance of surviving so they can be selected for.

	A.	Species do not change through time.
	B.	All species are unique.
	C.	Species cannot adapt to environmental changes.
	D.	All species will eventually go extinct.

After working through the macromolecules in your friendâs extremely pale burrito, you look at her and think you might have an idea about what is going on. You ask Maria, âDo you usually eat like this?â âYup,â she says, âI love all the carbs, rice, and bread, as well as cheese. Sometimes I eat a piece of fruit or some carrot sticks. And energy drinks!â You then point out to your friend that she seems to be getting very little protein, a major class of macromolecules. But she is getting plenty of carbohydrates and lipids in the form of animal fats.

1. While your body can convert the monomers of macromolecules from one to the other, it has to have the raw materials in the form of the appropriate atoms. You explain to your friend that when she eats proteins, they are broken down into amino acids through the process of INSERT ANSWER and can then be rebuilt into new proteins through the process of INSERT ANSWER.

a. If your body does not take in protein, but only carbohydrates and lipids, what atoms will it be missing? Hint: There are two, and you can figure this out by comparing the structures of the monomers for proteins and carbohydrates as well as the basic structure of lipids. INSERT ANSWER

b. For the above atoms, how many electrons are in the outer shell? INSERT ANSWER

c. For the above atoms, what type of bond will they make within the amino acid monomer? INSERT ANSWER

d. Even if your friend does obtain the correct atoms, there are still a couple amino acids that your body cannot manufacture from scratch, but must be ingested. What are these amino acids? INSERT ANSWER

e.Why might a lack of protein or the wrong types of proteins lead to your friendâs fatigue? INSERT ANSWER
