What is the difference between basic and applied sciences?
Basic = expands knowledge
Applied = aims to solve immediate problem
Which is/are the reactant(s)?
N2 and H2
What makes something organic?
Organic refers to molecules containing carbon atoms, typically bonded to hydrogen, oxygen, or nitrogen.
What is a cell?
Smallest unit of life
Van der waals interactions
weak attractions due to change in electron density
What is the difference between Inductive and Deductive reasoning?
Inductive = Observations that lead to a conclusion
Deductive = Principal or law to forecast result
What is an isotope?
Isotopes are different versions of the same chemical element. They all have the same number of protons and electrons, but varying numbers of neutrons in their nuclei.
What is this functional group?
Methyl Group

What do eukaryotic cells have that prokaryotic cells lack?
A nucleus
polymers
large molecules made by covalently bonded monomers
List the levels of organization. (Minimum 9)
Atoms, Molecules, Macromolecules, Organelles, Cells, Tissues, Organs, Organ Systems, Organisms, Ecosystems, Biosphere.
Define Ionic vs Covalent bond?
Ionic bonds form when electrons are completely transferred from one atom to another, creating oppositely charged ions that attract each other. Covalent bonds form when atoms share pairs of electrons to achieve stability
What are the 3 components of a nucleic acid?
(Bonus for added 100pts) What are the Pyrimidine and Purine bases? Name them.
- A nitrogenous base
- A pentose sugar
- A phosphate group
Pyrimidines: CUT
Purines: AG
What is the purpose of the endomembrane system?
to synthesize, modify, package, and transport proteins and lipids
Trans vs Cis Isomers
Cis and trans are prefixes used in chemistry to describe the spatial arrangement of atoms within molecules
- Cis: Functional groups or similar atoms are located on the same side of a molecular plane or double bond.
- Trans: (Latin for "across" or "the other side"): Identical or similar functional groups are positioned on opposite sides
Name 3 properties of life
Order, Sensitivity or Response to Stimuli, Reproduction, Growthy and Development, Regulation, Homeostasis, Energy Processing
Bonus: Worth 800pts!!!
Identify what subatomic units affects identify, charge, and weight of an atom.
protons = identity and weight
electrons = charge
neutrons = weight
Label the phospholipid
- Phosphate
- Glycerol
- hydrophilic head
- hydrophobic tails
- saturated and unsaturated fatty acids
What are the three components of cell theory?
1) cells are the basic unit of life
2) all living organisms are made of cells
3) all cells come from pre-existing cells
Cohesion vs adhesion
cohesion: the attractive force that holds similar molecules together
adhesion: the molecular attraction between dissimilar substances
