Asconoid = least complex; Syconoid; Leuconoid = most complex11. Integrated Taxonomic Information System12. Community Level13. A savanna is dominated by grasses and scattered trees. There is a fair amount of rainfallbut prolonged seasonal droughts are common and thus there is no forest. More varieties oflarge ungulates (like antelope) and their predators live here more than anywhere else.14. Both of these types of migration are typically seasonal. Latitudinal migration refers tomigration that occurs as animals move from one latitude to another (eg. north to south orsouth to north; not east to west) across the globe. Altitudinal migration refers to migrationfrom one altitude (topographical height) to another typically within a localized mountain range.15. Mitochondria require oxygen and glucose (or other molecules) made by chloroplasts.Mitochondria produce ATP and carbon dioxide and some water. Chloroplasts in turn needcarbon dioxide produced by mitochondria, water and sunlight to complete photosynthesis.16. Diffusion refers to a movement of molecules from an area of their higher concentration toan area of their lower concentration. Osmosis is the diffusion of a solvent (usually water)across a semi-permeable or selectively permeable membrane. This membrane only allowsspecific molecules to pass through usually based on molecular size and/or polarity (charge).
