Towards stimulus - answer positive response
Away from stimulus - answer Negative response
single celled organisms reproduction - answer Duplicate DNA> divide it equally> prepares to form two new cells
Multicellular organisms reproduction - answer Specialized germ line cells that form new individuals
Genes passed to offspring - answer Direct cell growth and development to ensure same characteristics
Regulation - answer Even small organisms require regulating mechanisms to coordinate internal functions, respond to stimuli, and cope with environmental stress (ex. Blood flow and nutrient transport)
Homeostasis - answer (Steady state) appropriate conditions such as temp, pH, and concentration of diverse chemicals
Energy Processing - answer All organisms use a source of energy for their metabolic

beta diversity - answer Species diversity between ecosystems, comparing number of
taxa that are unique to each ecosystem
gamma diversity - answer Measurement of overall diversity for different ecosystems within a region
benefits of biodiversity - answer Provides food, medicines, products, increases potential fro new products, and provides ecological services
phylogenetic tree - answer a diagram showing the evolutionary relationships among organisms or groups of organisms
