Biology Finals!!! Flashcards
Immigration
- movement of individuals into an area
- causes population growth
Emigration
- movement of individuals out of an area
- causes population decline
Reactants and products for cellular respiration?
Reactants: glucose and oxygen
Products: Carbon dioxide and water
Reactants and products for photosynthesis?
Reactants: carbon dioxide and water
Products: glucose and oxygen
Photosynthesis
- Organelle
- Reactants
- Electron Transport Chain
- Cycle of chemical reactions
- Products
- Chloroplast
- CO2 and H2O
- Makes ATP and NADPH to make sugar
- Calvin cycle builds sugar
- C6H12O6 and O2
Cellular Respiration
- Organelle
- Reactants
- Electron Transport Chain
- Cycle of chemical reactions
- Products
- Mitochondria
- C6H12O6 and O2
- Makes ATP to be used in cells
- Glycolysis breaks down sugar
- CO2 and H2O
Human activities affect population of other species?
- Loss of habitat
- habitat fragmentation
- Global Warming
- clear cutting
- deforestation
Mutualism
Both species benefit
Commensalism
ONE species benefits and one isn’t harmed
Parasitism
ONE species benefits and one is harmed
Abiotic examples
Water, temperature, wind, sunlight, moisture, soil
Biotic examples
Plants, animals, fungi, bacteria
Depends on abiotic factors
How is carbon removed and put back into the atmosphere?
Removed: photosynthesis, dissolves in ocean, acid rain
Put back: burning of fossil fuels (combustion), cellular respiration, forest fires, volcanic eruptions, décomposition of living things
Natural selection
Certain physical traits are more fit Components: Variation Overproduction Adaptation Descent w modification
Fitness
Ability to survive in an environment
How does a genotype affect its fitness
Genes affect a physical trait
Homologous structures
Similar structures
Different functions
Analogous
Different structures
Same function
Vestigial structures
Once had a function
Species
A group of organisms that interbreed and produce fertile/viable offspring
Speciation
New species (divergence); when a population is separated and evolves separately
Decrease in CO2
Land plants and trees
Using renewable resources
Greenhouse effect
Slows the release of energy from earths atmosphere
Traps in heat, causing temperatures to rise
DOES NOT BRING MORE HEAT IN
Effects of deforestation
Increase in CO2
Habitat loss
Loss of biodiversity
How do humans affect the environment
Pressure on resources
Air pollution (fossil fuels)
Water pollution (fertilizers, oil spills)
Habitat loss (urban sprawl, deforestation)
Invasive species
Pure science
Answer questions
Applied science
Scientific knowledge to develop technology or inventions
Relationship between energy and biomass
Biomass and energy decrease
If biomass is consumed energy is lost as heat and waste
Trophies levels
Producers
