O2 + light + H2O --> CO2 + Sugar
CO2 + O2 + H2O --> Light+ Sugar
Which of the following situations is MOST likely to result in the formation of a new species?
A population of squirrels lives in a stable forest habitat.
A population of birds lives in a stable forest habitat.
A population of squirrels lives in an area where a large river forms and cuts through the middle of the forest.
A population of birds lives in an area where a large river forms and cuts through the middle of the forest.
From the graph above, what can you conclude about speciation and extinction rates in different parts of the world?
The speciation and extinction rates are both higher in tropical areas than they are in temperate areas.
The speciation and extinction rates are both higher in temperate areas than they are in tropical areas.
The speciation rates are higher in tropical areas than they are in temperate areas, while the extinction rates are higher in temperate areas than they are in tropical areas.
The speciation rates are higher in temperate areas than they are in tropical areas, while the extinction rates are higher in tropical areas than they are in temperate areas.
Which of the following factors would likely contribute to an increase in the number of species in an ecosystem? Select All that apply.
Faster formation of species from natural selection.
Stability or instability within the ecosystem
A reduction in the extinction rate.
New environmental factors with which organisms must cope.
The environment is constantly changing due to weather patterns, geological events, and human activity.
If a species cannot adjust to these changes in order to successfully reproduce, then it is MOST likely that the species will
Develop new adaptations to accommodate for the environmental changes
Become extinct.
Form a new symbiotic relationship with another species
Migrate to a new environment that will meet its needs.
What is the correct equation for cellular respiration?
6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy
6O2 + C6H12O6 + Energy -> 6CO2 + 6H2O
6CO2 + 6H2O -> 6O2 + C6H12O6 + Energy
6CO2 + 6H2O + Energy -> 6O2 + C6H12O6

Select all the evidence that plate tectonics helped with earth's evolution.
Continent alignment - continents fit together almost like puzzle pieces
Fossil placement - the same species of organism can be found across certain areas (that linked in Pangaea) on very different parts of the globe
Mountain belts - mountain chains from Pangaea are now split up and on multiple continents
Glacial evidence - glaciers (in southern Pangaea) show that modern day continents were once clustered near the South Pole
