1
Q

Climate Change

A

A persistent and significant change in the measures of climate, the average weather condition in a given region

2
Q

Enzymes

A

Catalysts, chemical compounds (in this case biological molecules) that speed up chemical reactions, by lowering the activation energy needed for the reaction

3
Q

Global Warming

A

An overall warming of Earth as indicated by an increase in its average surface temperature

4
Q

Performance

A

How effectively an individual or population executes a given biologic task

5
Q

Population

A

In ecology, a group of individuals of the same species living within a defined area at the same time

6
Q

Intrinsic (Population) Growth Rate (r)

A
The population growth rate, per individual, for a population with unlimited resources
r=b-d
r=Intrinsic Growth Rate
b=Average Birth Rate
d=Death Rate
7
Q

Ectotherms

A

An organism whose body temperature is primarily determined by heat from its environment

8
Q

Temperature Performance Curve

A

A curve that describes how the expression of a particular trait (growth rate, movement rate, catalytic rate of an enzyme, etc) varies with temperature

9
Q

What is Tmin, Tmax, and Topt?

A

Tmin is the lowest temperature something changes, Tmax is the highest temperature something changes, and Topt is the temperature something changes the most
