Chemistry
Atoms of the same element with differing numbers of neutrons
What are isotopes?
The maximum population size of a species that its environment can sustain
What is carrying capacity?
The three types of rock
Igneous, Metamorphic, Sedimentary
Soil low in nutrients & high in salts, animals are small, extreme temperature changes between day and night
What is a desert biome?
The actual part of a species' functional role in an ecological community that it performs
What is realized niche?
Bonus 200: Describe specialists and generalists
A bond that connects the positive region of one water molecule to a negative region of another water molecule
What is a hydrogen bond?
A species' capacity to produce offspring
What is biotic potential? What is intrinsic growth rate?
Subduction and continental collision
What are the two types of convergent plate boundaries?
Found in mid-latitudes, vegetation is primarily oak, maple, beech, 4 distinct seasons, medium amount of rainfall, cold winters, warm summers.
What is temperate deciduous forest biome?
A killing frost decimates deer populations in a forest ecosystem
What is density independent factor?
Energy becomes less ordered in the absence of counteracting forces
What is the second law of thermodynamics?
Small body size, early maturity, large broods, little or no parental investment
What are R-selected species?
Where two tectonic plates meet, resulting in slipping and grinding. Hallmarked by faults and earthquakes.
What is a transform plate boundary?
Coniferous forests, short growing seasons, cold winters & cool summers, little rainfall, mostly small animals, some larger animals like moose.
What is boreal forest biome?
The boxer crab carries a pair of small anemones in its claws. When a predator approaches, it waves the anemones around which presents its stinging tentacles and deters the predator. The anemones get small particles of food from the crab when it eats.
What is mutualism?
Proteins, Carbohydrates, and Nucleic Acids
What are the three biologically essential polymers?
Begins in an environment following a disturbance that dramatically alters an existing community but does not destroy all life and organic matter.
What is secondary succession?
A portion of the upper mantle containing especially soft rock
What is the asthenosphere?
Biome that has little temperature variation, receives plentiful amounts of rain, abundant primary productivity, many animal and bird species, found at mid-latitudes
What is temperate rainforest?
A cuckoo may lay its eggs in a warbler's nest. The cuckoo's young will displace the warbler's young, and the warbler will raise the cuckoo's young.
What is interspecific competition?
A process powered by sunlight through which molecules with low-energy bonds are converted into molecules with many high-energy bonds
What is photosynthesis?
One ancestral population is split by some physical factor over geographic distance. Overtime, they become so different they can’t reproduce with each other anymore.
What is allopatric speciation?
Name the layers of the Earth
Inner core -> outer core -> lower mantle -> asthenosphere -> uppermost mantle -> crust
Biome of North Texas
What is temperate grassland?
Predators at high trophic levels can indirectly promote populations of organisms at lower trophic levels by keeping species at intermediate trophic levels in check.
What is Trophic Cascade?
Bonus 50: What are keystone species?
