- learned behavior
- photic zone
- a Behavior that an organism picks up over the course of its life. Three types of learned behavior are habituation, conditioning, and associative learning.
- b Literally, zone with light. The photic zone is part of the marine pelagic zone and extends to 600 feet below the surface of the ocean. Photosynthetic plankton as well as bony fish, sharks, and whales inhabit this zone.
- c The process in which haploid egg cells (ova) form through meiotic division.
- d An evolutionary theory (proved false by Darwin) stating that species change over time by the use and disuse of structures and the inheritance of acquired traits.
- e 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.

- Steps on a food/biomass pyramid that are defined by organisms within a community that are the same distance from the primary producers in a food web.
- A simple cluster of nerve cells that acts as a coordinating center. In more sophisticated organisms, ganglia evolved into a brain and spinal cord.
- Small epidermal pores, surrounded by two guard cells, through which gases diffuse and water transpires in and out of a leaf.
- The organ of blood filtration in humans. The functional unit of the kidney is the nephron.
- The inability of individuals within a species to create offspring with members of any other species. The mark of a species is its reproductive isolation from all other species.
5 True/False questions
auxin → One in a class of plant hormones that stimulates (among other things) cell elongation, secondary tissue growth, and fruit development.
root hair → Many connected food chains that exhibit the relationships of all predators to all prey constitute a food web.
nephron → Tiny, tubule structures responsible for the filtering of blood in the kidneys of vertebrates.
vegetative propagation → A form of asexual reproduction in which plants produce genetically identical offshoots (clones) of themselves, which then develop into independent plants.
dicot → A flowering plant (angiosperm) that possesses two cotyledons during embryonic development. Usually has taproots, flower parts in multiples of fours and fives, and branching veins in leaves.
