They are for energy storage, as well as structure in plants.
What are carbohydrates?
100
It's the smallest unit of matter.
What is an atom?
100
It's the chemical formula of water.
What is H20?
100
It is the negatively-charged particle that's involved in bonding atoms.
What is an electron?
100
They are the three elements found in all organic molecules.
What are carbon, hydrogen and oxygen?
200
A kind of nucleic acid, its job is to make proteins.
What is RNA?
200
They're the three subatomic particles that make up atoms.
What are protons, neutrons and electrons?
200
Water becomes less dense as it freezes, because it does this when it turns into its solid state.
What is expand?
200
This strong bond forms from the attraction created when one atom takes another's electrons.
What is an ionic bond?
200
When added to a water solution, these make a lot of hydrogen ions (H+).
What are acids?
300
They're the kind of lipid that make up cell membranes.
What are phospholipids?
300
These particles have an atomic mass of 1 and determine what element is what.
What are protons?
300
Unequal sharing of electrons gives water this property of having a slight positive charge on one end and a slight negative charge on the other end.
What is polarity?
300
In this kind of bond that holds together the macromolecules we study, electrons are shared between atoms.
What is a covalent bond?
300
They're the weak bonds that help gecko feet climb up walls.
What are van der Waals forces?
400
Monosaccharides, or single sugars, are the monomer of this macromolecule.
What are carbohydrates?
400
They orbit the nucleus of an atom and have a charge of -1.
What are electrons?
400
It's due to the hydrogen bonding between water molecules, which makes them "stick together" and have surface tension.
What is cohesion?
400
It's the weak bond that forms from the (+) to (-) attraction when water molecules get close to each other.
What is a hydrogen bond?
400
This solution has a pH above 7.
What is a basic solution?
500
Made up of amino acids, they're the kind of macromolecule that can have many functions which includes acting as a biological catalyst in chemical reactions.
What are proteins?
500
If you change the number of these in an atom, you get an isotope.
What are neutrons?
500
Some living things (like plants) count on this ability of water to climb up narrow tubes against the force of gravity.
What is capillary action, or adhesion?
500
Although strong, these bonds dissolve easily in a water solution.
What are ionic bonds?
500
It's the pH of a solution that has a lot of hydrogen ions (H+) in it.
