• Nitrogen - 78% of Earth's atmosphere
• Cell wall - structural layer around the cell which provide support and protection
• Mitochondria - powerhouse of cell
• Ribosome - intercellular structure made from RNA which reads the messenger.
• Law of Gravity - proportional is the product of masses and inversely proportional is the squared of distance in between.
• Law of Force (1st law) - object will not change in motion unless force is applied.
• Law of Inertia - object at rest will remain at rest unless acted upon by an unbalance force.
• Prescription - medical instruction
• Cell Membrane - guard of the cell
• F = exerted joules of forces times meter traveled
• Condensation - gas to liquid
• Glucose and Amino acids are reabsorbed in Proximal Tabule.
• Evidence of artificial selection in domestic animals DID NOT help Charles Darwin in formulation theory of evolution.
• Front flipper of a porpoise and human arm are example of analogous structures.
• Cells - smallest or lowest level
• Regulating materials that enter or leave system are NOT property of life.
• Gonorrhea is difficult to treat because of causative bacteria in Hawaii. Its germs change its genetic code to avoid problems with antibiotics.
• Capsule is the slippery outer covering of bacteria that protects it from phagocytosis (host cell).
• Flagellum is the slender threadlike structure that allows many protozoa, bacteria, spermzoa, etc. to swim.
• Peptidoglycan (mesh) is a rigid envelope surround cytoplasmic membrane of most bacteria.
• Eukaryotic cells have mitochondria, cilia, and flagella with complex structures.
• Prokaryotic cells does not have genetic materials and no more complex cell walls.
• Optimum temperature of an organism is the one at which grows with the shortest generation time.
• Leaves, roots, and seeds are where sugar is stored as starch.
• ADP energy is used for all energy-requiring process in cells. 
• Cytoskeleton gives cell shape, anchor organelles, and allows organelles to move.
• Red blood cell plasma membrane is over 20 different types of proteins.
• STAGES OF CELL DIVISION (MITOSIS AND MEOSIS)

  Prophase - Prometaphase - Metaphase - Anaphase
• Prophase - the condensation of chromatin reticulum and DNA is already replicated.
• Prometaphase - nuclear envelope break down creating mitotic spindle.
• Prometaphase - chromosomes are attach to the spindle and align in the metaphase plate spindle (middle).
• Anaphase - separates duplicated genetic material into two identical daughter cells.
• Dihybrid Cross - true-bleeding plants which differ in two traits.
• Hybrid Cross - cross between two different species that are not closely related.
• Realized niche of an organism is narrower.
• Vertebrate skeleton - living tissue which grows the animal, protect internal organs, and serves as a place of attachment for muscles.
• Protoplast is a cell without a wall.  
• Cell wall is the main difference between Gram positive and Gram negative bacteria.
• Fibers is the correct pathway for propagation of cardiac impulse.
• Ciliated Epithelium - line inner surfaces of bronchi, bronchioles, and fallopian tube.
