The exam will cover the entire allotted time period.

Resources for Studying

Review videos from Amoeba Sisters, Bozeman Science, Crash Course, and Khan Academy.
Review study guides and analysis packets to assess understanding.
Utilize Quizlets and Mastering Biology videos.
Use AP Classroom videos and questions.

Study Skills

Work through blank analysis packets, checking answers.
Collaborate with a study partner to clarify concepts, and develop alternative methods.
Create note guides, focusing on unclear aspects.
Use the textbook's vocabulary flashcards (or Quizlets) to reinforce key terms.
Explain the material to oneself or others for deeper understanding.

Group Goals

Create a study guide with concepts, terms, and diagrams.
Comparisons are helpful (e.g., active vs. passive immunity).
Indicate difficulty scores for each chapter (1 to 3), with 1 representing fewer questions.

Experimental Design

Independent Variable: Factor being tested.
Dependent Variable: Measures the response to the IV.
Control Variables: Factors kept constant.
Experimental Group: Receives experimental treatment.
Control Group: Used for comparison.
Negative Control: Placebo; no treatment.
Trials: Number of repetitions.

Basic Chemistry

Four most common elements: C, H, O, N.
Energy levels of electrons: High/low shells are closer/further from the nucleus.
Chemical bonds: Single, double, etc., based on electrons shared.
Electronegativity: An atom's attraction for electrons in a chemical bond.
Polar vs. Nonpolar bonds: Polar bonds have unequal sharing; Nonpolar bonds have equal sharing of electrons.
Molecular shape affects function.
Hydrogen bonds: Form through partially negative/positive charges (e.g., hydrogen is partially positive, oxygen is partially negative).

Water

Cohesion: Attraction of like molecules.
Adhesion: Attraction of unlike molecules.
Capillary Action: Liquid flow in narrow tubes due to cohesion and adhesion.
Surface Tension: Liquid's resistance to rupture from cohesion.
Specific Heat: Amount of heat required to change water's temperature.
Evaporative Cooling: Heat carried away when water evaporates.

Carbon Compounds

Isomers: Molecules with the same formula, but different atom arrangement.
Functional Groups: Specific groups of atoms (e.g., Hydroxyl -OH; Carboxyl -COOH; Amino -NH2; Sulfhydryl -SH; Phosphate -PO4).
Each functional group has specific properties that affect the behavior of the molecule.
