Define neuroscience, nervous systems, and neurons. - Neuroscience: any science that deals with the structure or function of the nervous system or the brain Neurons: cells that send and receive electrical or chemical signals (nerve cells) Nervous systems: circuits of neurons that integrate internal and external information How do neurons and nervous systems differ in association with species complexity? - More complex organisms have more complex nervous systems and more neurons (hydra--&gt...

What is a covalent bond? - When two atoms share electrons What are the three key polar covalent bonds (for the sake of this class)? - O-H, N-H, S-H What can H bond to? - Other polar molecules and water. How are polymers built? - Through dehydration reactions (Monomer in, water out) How are polymers broken down? - Through hydrolysis reactions (Water in, monomer out) What is the identifying shape of a carbohydrate? - Ring-shaped What is the function of a disaccharide? - To be bro...

What is biological evolution? - Heritable change in a population across many generations. What is the difference between microevolution and macroevolution? - Microevolution is on a small scale. It is a change in a single gene. Macroevolution is on a large scale and results in the formation of a new species. What is a scientific theory (definition)? - A well-tested concept that explains a wide range of observations. What is catastrophism? - The idea presented by Georges Cuvier that major...
