- a A blood filtration and excretory organ characteristic of segmented worms.
- b A situation in which the concentration of solutes in a solution is lower than what an organism contains. An example is a paramecium in pond water: the organism has more solutes than its environment, so water flows into the cell by osmosis. Paramecia have evolved contractile vacuoles to keep from exploding.

5 True/False Questions
Calvin cycle → The cycles in which inorganic elements move through the biotic and abiotic aspects of an ecosystem. The two most important chemical cycles are the carbon and nitrogen cycles.
autotroph → An organism that can produce the organic molecules and energy necessary for life through the processes of photosynthesis or chemosynthesis. Autotrophs do not rely on other organisms for food. In a food web, autotrophs are producers.
imprinting → A blood filtration and excretory organ characteristic of segmented worms.
cellulose → A firm but flexible substance, found in regions of vertebrate skeletons, such as the ribs, that need to bend.
community → Process by which water naturally travels from an area of high water concentration to low water concentration.
