Atomic Structure
What is the term for a substance that cannot be broken down into other substances?
Element
Type of chemical bond that can form single and double bonds.
Covalent Bond
What is an ecosystem?
All of the living organisms and the nonliving things of the environment they interact with.
What is the ability for an organism to create more of their own kind?
Reproduction
What is a Hypothesis?
A scientific prediction
What does the mass number of an element represent?
All of the protons and neutrons in an atom.
What are the particles involved in an ionic bond and what are their charges?
Cation (Positive)
Anion (Negative)
What is the difference between a Population and a Community?
A population includes all members of a single species, A community includes multiple species
What structure is genetic material formed into within cells?
Deoxyribonucleic Acid (DNA)
What are the names of the outermost electrons of an atom and what are they stored in?
Valence electrons, Valence shell
What is the difference between different isotopes of the same element? (i.e. Carbon-12 vs Carbon-14)
They have a different number of neutrons.
What chemical bonds are present in a glass of water?
Polar covalent bonds (within water), Hydrogen bonds (between water)
What are the levels of organization from Molecule to Organism?
Molecule, Organelle, Cell, Tissue, Organ, Organism
What are the main 2 types of cells and what is the main difference between the 2?
Prokaryotes & Eukaryotes
Eukaryotes have many membrane-bound organelles, Prokaryotes have no nuclei and organelles
What are the parts of a chemical reaction and describe them?
Reactants - Starting materials
Product - Resulting materials
What are the particles that make up an atom and what are their charges?
Proton (Positive)
Neutron (Neutral)
Electron (Negative)What are the types of covalent bonds and how are they different from each other?
Polar & Nonpolar
Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.
What are the levels of organization above Organism, in ascending order?
Population, Community, Ecosystem, Biosphere
What properties of life does photosynthesis represent?
Response to environment/stimuli (Interactions)
Energy processing (Energy and Matter)
What can possibly occur after Analysis of an experiment's results?
Conclusion
Revision of Hypothesis (Hypothesis is wrong)
What is the relationship between potential energy and electron shells?
As the number of electron shells increase, the amount of potential energy increases.
How do Van der Waals Interactions work?
What are emergent properties?
Novel properties that emerge at each level that are absent in previous levels, due to the arrangement and interaction of parts as complexity increases.
What is the definition of evolution?
The process of biological change in which species accumulate differences from their ancestors as they adapt to different environments over time.
Describe chemical equilibrium.
The point in which the forward and reverse reactions occur at the same rate, stopping the change of the relative concentration of products and reactants.
