Question 1

Climate Change

Answer 1

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

Question 2

Enzymes

Answer 2

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

Question 3

Global Warming

Answer 3

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

Question 4

Performance

Answer 4

How effectively an individual or population executes a given biologic task

Question 5

Population

Answer 5

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

Question 6

Intrinsic (Population) Growth Rate (r)

Answer 6

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

Question 7

Ectotherms

Answer 7

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

Question 8

Temperature Performance Curve

Answer 8

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

Question 9

What is Tmin, Tmax, and Topt?

Answer 9

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