cellular respiration - correct answers the breakdown of sugar in the presence of oxygen ATP - correct answers adenosine triphosphate: an energy-rich nucleotide -helps transfer energy to other molecules and helps drive mechanical , transport, and chemical work in the cells A nucleotide consists of: - correct answers -a nitrogenous base -a phosphate -a sugar phosphorylation - correct answers the addition of a phosphate group to a molecule what makes up ATP? - correct answers ADP + phosphate what can be broken down in cellular respiration? - correct answers carbs, fats, and proteins what is cellular respiration also known as? - correct answers aerobic respiration (because oxygen is used in the process) the usable form of energy produced by cellular respiration is - correct answers ATP what is the general equation for cellular respiration? - correct answers glucose + oxygen - carbon dioxide + water (and ATP) what is the site of cellular respiration? - correct answers mitochondria fermentation - correct answers the breakdown of nutrients in the absence of oxygen -anaerobic process -yields less energy than cellular respiration Growth Rate - correct answers (birth rate - death rate) = r Population growth - correct answers growth rate x population carrying capacity - correct answers the maximum population that can be supported indefinitely in a given environment why does growth rate decline as a population reaches capacity? - correct answers reduction in birth rate, increase in death rate, or bot exponential growth curve - correct answers results in J shaped curve of population increase over time logistic growth curve - correct answers S shaped curve of population increase over time density dependent factors - correct answers competition, disease, food supply density independent factors - correct answers natural disasters, human impacts doubling rate - correct answers time for population to double in size -indicates exponential growth population crash - correct answers a steep decline in the size of a population net primary production (NPP) - correct answers amount of solar energy converted to chemical energy by plants, minus the energy required of plants to support themselves how is efficient human food production done? - correct answers agriculture Biological diversity (biodiversity) - correct answers the variability among living organisms and the ecological systems of which they are a part. Modern species are divided into three large groups, what are they? - correct answers Bacteria Archaea Eukarya Within Eukarya, four kingdoms are also recognized, what are they? - correct answers Plantae Animalia Fungi Protista biome - correct answers primary vegetation type -forest -grassland -desert -tundra aquatic biomes (fresh water) - correct answers -ponds -lakes -wetlands -streams and rivers aquatic biomes (salt water) - correct answers -oceans -coral reefs -estuaries (Zone where freshwater river drains into salty oceans) el nino - correct answers -Heavy rains on islands of Pacific and the west coast of South America -Drought in Australia, Indonesia, and the Philippines -Warmer-than-normal winters in northern US and Canada -Drought in Africa and India -Weakening of Atlantic hurricanes -Greater precipitation in SW United States rain shadow - correct answers A rain shadow is a dry area on the lee back side of a mountainous area. The mountains block the passage of rain-producing weather systems casting a "shadow" of dryness behind them. photosynthesis - correct answers Process by which light energy transformed to chemical energy what is the ultimate source of energy for living organisms? - correct answers Sun Salinization - correct answers increased levels of salts in soil by irrigation Irrigation water contains small amounts of minerals as salts. As water removed from soil, salts accumulate. Eventually, soil not fit for plant growth. Desertification - correct answers degradation of soil through erosion and salinization. Biomagnification - correct answers concentration of persistent toxic chemicals at higher levels of a food web. Eutrophication - correct answers low oxygen levels in water caused by high levels of fertilizer runoff that causes increased growth of algae. Modern farming practices attempt to maximize - correct answers light water carbon dioxide nutrients modern farming practices attempt to minimize - correct answers weeds herbivores (damage from pests) what promotes growth of blooms and fruit? - correct answers phosphorous After the gene from one organism is inserted into the genome of another organism, the result is - correct answers a transgenic organism and recombinant DNA the function of the stomata - correct answers allow carbon dioxide to enter the plant body which part of the plant is a white potato? - correct answers a stem, modified for food storage Agriculture - correct answers cultivation of crops, raising of livestock. Domesticated plants - correct answers plants that are the products of artificial selection -Live in disturbed areas. -Produce greater yield. -Cannot survive without human intervention. 5 organs of plants - correct answers vegetative: -roots -stems -leaves reproductive: -flowers -fruit Tubers - correct answers stems that have been modified for food storage Tilling - correct answers turning over soil to kill young weed plants. Mulching - correct answers covering soil to prevent weeds from gaining exposure to light. stoma - correct answers pores which Carbon dioxide must enter the leaf through Inorganic fertilizer - correct answers industrial based, simple molecules organic fertilizer - correct answers non-industrial based, complex molecules Crop rotation - correct answers alternate crop plants in field from year to year. Removes resources from last year's pests (changes habitat).
