Wild Card
This is what enzymes do to the rate of chemical reactions.
What is speed them up?
What is the process of rain or snowfall called?
precipitation
Why must nitrogen be "fixed"?
the N2 gas in the air is not in a form that is usable by plants or animals
The place on the enzyme where the substrate binds.
What is the active site?
What is the process of turning a liquid into a gas?
Evaporation
The process of burning fossil fuels, releasing carbon, is called?
combustion / Emissions
How does nitrogen fixation occur?
nitrogen-fixing bacteria
Organelles float in this jellylike fluid inside the cell.
What is cytoplasm?
How does water vapor from the atmosphere form into clouds?
condensation
Why is nitrogen so important?
it is used to make amino acids, and ultimately proteins, allowing plants and animals to grow
Law enforcement uses DNA fingerprinting mainly for this purpose.
What is solving crimes (forensic identification)?
What two things can happen with water after precipitation has returned it to the ground?
Percolation/Infiltration and Surface Runoff
In what process do animals return carbon to the atmosphere?
respiration
How do humans get the nitrogen that they need?
Consumption (Eating!)
This viral cycle allows the virus to stay hidden in the host’s DNA for a while.
What is the lysogenic cycle
What is transpiration?
the evaporation of water from plants
How have humans drastically altered the carbon cycle?
burning fossil fuels which releases carbon dioxide
What is one way Nitrogen can be fixed WITHOUT bacteria?
Lightening!
