A+ Verified
• Cell . Answer: Basic unit of life
• Community . Answer: All the different populations that live together in an area
• Ecosystem . Answer: A biological community of interacting organisms and their
physical environment.
• Macromolecule . Answer: A very large organic molecule composed of many smaller
molecules-technically polymers
• Molecule . Answer: A group of atoms bonded together
• Organ . Answer: A collection of tissues that carry out a specialized function of the body
• Organ System . Answer: A group of organs that work together in performing vital body
functions.
• Organism . Answer: Any living thing
• Population . Answer: A group of individuals that belong to the same species and live in
the same area
• Tissue . Answer: A group of similar cells that perform the same function.
• Scientific Inquiry . Answer: The diverse ways in which scientists study the natural
world and propose explanations based on evidence they gather.
• Atom . Answer: Basic unit of matter
• Covalent bonds . Answer: Bonds created by sharing electrons with other atoms.
• Chemical Bonds . Answer: An attraction between two atoms resulting from a sharing of
outer-shell electrons or the presence of opposite charges on the atoms. The bonded
atoms gain complete outer electron shells.
• Electronegativity . Answer: A measure of the ability of an atom in a chemical
compound to attract electrons
• Electron . Answer: A subatomic particle that has a negative charge
, • Hydrogen Bonds . Answer: Very weak bonds; occurs when a hydrogen atom in one
molecule is attracted to the electrostatic atom in another molecule
• Ionic bonds . Answer: Formed when one or more electrons are transferred from one
atom to another
• Neutron . Answer: A subatomic particle that has no charge and that is found in the
nucleus of an atom
• Proton . Answer: A subatomic particle that has a positive charge and that is found in
the nucleus of an atom
• Adhesion . Answer: An attraction between molecules of different substances. Sticks to
others!
• Cohesion . Answer: Attraction between molecules of the same substance. Sticks to
itself!
• Hydrophilic . Answer: Attracted to water
• Hydrophobic . Answer: Water fearing
• Surface Tension . Answer: A measure of how difficult it is to stretch or break the
surface of a liquid
• Solute . Answer: A substance that is dissolved in a solution.
• Solutions . Answer: A mixture where substances are distributed evenly. Has a solvent
& solute.
• Solvent . Answer: A liquid substance capable of dissolving other substances
• Amino Acids . Answer: building blocks of proteins and monomers
• Carbohydrates . Answer: the starches and sugars present in foods. Broken down into
simple sugars
• Enzymes . Answer: Catalysts for chemical reactions in living things
• Fats . Answer: lipids that are solid at room temperature
• Glucose . Answer: the form of sugar that circulates in the blood and provides the major
source of energy for body tissues. When its level is low, we feel hunger.
• Inorganic molecules . Answer: Compounds that do not contain carbon
