This is the main requirement for a scientific hypothesis.
What is testable?
The three subatomic particles.
What are protons, electrons and neutrons?
These types of molecules can be dissolved in water.
What are polar molecules?
The fatty acid with one or more double bonded carbons, resulting in a kink in the acid chain.
What is an unsaturated fatty acid.
A molecule made by a living orginism to speed up chemical reactions.
What is an enzyme?
This is the variable in an experiemtnt that effects the dependant variable.
What is an independant variable?
The name of the bond between elements when the electron is fully taken from one atom to the other.
What is an ionic bond?
The functional group NH2.
What is the amino group?
Lysine, serine and alanine are examples of these kinds of molecules.
What are amino acids?
The part of an enzyme that can bind with a substrate.
What is an active site?
Guanine binds with this nucleic acid.
What is cytosine?
The four most common elements on earth.
What are carbon, nitrogen, oxygen and hydrogen?
When a substance has a pH of 0 to 7.
What is an acid?
Guanine bonds with this nucleic acid.
What is cytosine?
When an enzyme will slightly change its shape in order to better hold a substrate.
What is an induced fit?
The process of carefully breeding plants or animals in order to produnce more of a desirable trait.
What is artifical selection?
The type of bond made when the elements have an electronegativity difference of 0.4 to 1.8.
What is a polar colvalent bond?
The element that is the back bone of the four classes of biomolecules, protein, carbohydrate, nucleic acids, and lipids.
What is carbon?
This reaction bonds two or more monomers into a single polymer.
What is the dehydration reaction?
A molecule that binds to an enzyme to increase actitivity.
What is an enzyme activator?
Random geneitic changes that can be harmful, neutral or helpful.
What is mutation?
An element with a different number of neutrons than protons.
What is an isotope?
These elements have no valence electrons.
What are the noble gasses?
The name of the bond of two amino acids.
What is a peptide bond?
Enzymes are modified (activated or inhibited) in these two ways.
What are cleavage and covalent bonds?
