What is the ozone layer
Thins as a result of widespread use of certain chlorine-containing compounds.

100

What is imprinting
Term used to describe the phenomenon in which young ducks follow their mother in a line

100

What is the greenhouse effect
The process in which CO2, CH4, and water vapor in the atmosphere intercepts and absorbs reflected infrared radiation and re-reflects it back to Earth.

100

What is substrate
Enzyme Catylysis (Lab 2): You should add more of this in efforts to keep the reaction constant over a period of time.

100

What is DPIP
Photosynthesis (Lab 4): Acted as an electron acceptor.

200

What is grass
Considered the major primary producer in a savanna ecosystem.

200

What is classical conditioning
The term usd to describe when Pavlov's dogs learned to salivate when they heard the ring of a particular bell.

200

What is density dependent limiting factor
Increased predation by a predator, a limited number of nesting sites, intraspecific competition, and/or a stress syndrome that alters hormone levels could all be considered this.

200

What is Net productivity
Dissolved Oxygen (Lab 12): term used to describe the organic materials that remain after photosynthetic organisms in the ecosystem have used some of these compounds for their cellular energy needs.

200

What is primary productivity
Dissolved Oxygen (Lab 12): Can be measured in three ways: 1. measure the amount of CO2 used. 2. Measure the rate of sugar formation. 3. Measure the rate of oxygen production.

300

What is carrying capacity
The maximum population size that a certain environment can support at a particular time.

300

What is habituation
A loss of responsiveness to stimuli that convey very little or no information. (Ex. cats no longer run to their food bowl in the mornings because their owner stops feeding them during that time of the day.)

300

What is keystone species
Removal of this species could result in a severe reduction in species diveresity for that communitiy.

300

What is cold and fast moving
Dissolved Oxygen (Lab 12): High amounts of DO are found in this type of water (two describing words)

300

What is Kinesis
Animal Behavior (Lab 11): Pill bugs will display this type of movment when exposed to a dark and wet environmet.

400

What is biome
Major types of ecosystems that occupy broad geographic regions.

400

What is Fixed action pattern (FAP)
Sticlebacks, a type of fish, display this type of behavior in response to a sign stimulus.

400

What is Type I survivorship
Humans and large mammals display this type of curve which begins steady and stable (reamins level), but then drastically declines in mortality when an old age is reached.

400

What is denaturing of the enzyme/active site. (a.a.)
Enzyme Catalysis (Lab 2): Adding H2SO4 stopped the reaction rate for all the trials because it caused this.

400

What is water potential
Diffusion/Osmosis (Lab 1): This increased when water moved into the potato cells (not mass).

500

What is eutrophic
A term that descibes a lake that is nutrient rich and supports a vast array of algae.

500

What is Altruism
An animal behavior in which one memeber of a population risks or sacrafices its own life for the well being of the rest of the population.

500

What is mutualism
One example of this is when Oxpeckers ride on the backs of rhinocerouses and eat various skin parasites, such as ticks.

500

What is photosynthesis and respiration
Dissolved Oxygen (Lab 12): This can increase DO (not temperature change) and this, on the other hand, can decrease DO.

500

What is KOH
Cellular Respiration (Lab 5): This was added because it binded with carbon dioxide to form a solid, preventing CO2 production from affecting gas volume.
