- respiratory system
- myelin sheath
- a A structure that speeds the movement of action potentials along the axon of a neuron. The sheath is built of Schwann cells, which wrap themselves around the axon of the neuron, leaving small gaps in between known as the nodes of Ranvier.
- b The many populations that interact in a given geographical locale constitute ecological communities. Communities exhibit particular interactions such as competition, symbiosis, predation, and food relationships. They also undergo ecological succession.
- c Having an affinity for water; usually polar molecules. For the SAT II Biology, this is principally important in relation to the phospholipid bilayer.
- d The organ system responsible for the intake of oxygen and diffusion of that gas into the blood and the elimination of carbon dioxide from the body. Important structures of the system are the pharynx, larynx, trachea, bronchi, bronchioles, and lungs. Alveoli in the lungs are the location of gas exchange with the blood. The movement of the muscular diaphragm allows the lungs to inhale and exhale.
- e Organisms that can only get the organic molecules and energy necessary for life through the consumption of other organic matter. In the food web, all consumers and decomposers are heterotrophs. Heterotrophs can be herbivores, carnivores, or omnivores.

- The study of the interactions and relationships of populations with each other and their abiotic environments.
- A means of returning blood fluid, lymph, that has escaped from capillaries back into the bloodstream. Defended against foreign bodies by lymphocytes.
- The maximum number of individuals in a population that can be sustained in a given environment. As populations become increasingly concentrated, competition for food and space, predation, and disease all determine carrying capacity.
- A complex carbohydrate that constitutes the cell walls of plants and protist molds.

stamen → The male reproductive organ of the flower, consisting of an anther and filament.
nitrogenous base → Form of endocytosis during which liquids are taken into the cell through the invagination of the cell membrane.
climax community → A sugar compound consisting of two carbohydrate monomers.
vascular cambium → Tissue that produces new vascular cells; lies between the xylem and phloem in dicot stems.
gymnosperm → A vascular flowering plant in which seeds are enclosed inside protective ovaries, such as fruit or flowers. Angiosperms can be monocots or dicots.
