Biology - Finals Review (PART ONE)

What goes on the X-AXIS of a graph?

The independent variable

What goes on the Y-AXIS of a graph?

The dependent variable

What information would you use to create a title for a graph?

The subject of the data

What type of graph would you use to show growth over time?

A time-series graph

What type of graph would you use to show how many people like certain colors?

A bar graph

On a line graph with two variables, which variable is affected by the other variable?

The dependent variable

What is a logistic growth curve?

A curve seen in graphs showing a population that grows and then plateaus once it reaches its carrying capacity

What is an exponential growth curve?

A curve seen in graphs showing a population that grows exponentially and never plateaus

What is the shape of a logistic growth curve?

An S

What is the shape of an exponential growth curve?

A backwards L

If you graphed populations of a predator and its prey, how would the two lines on the graph look?

The lines would always go the opposite direction of each other

What is a trophic level?

A feeding level on a food web or ecological pyramid

If there are 200 units of energy, how much will be left in the fourth trophic level?

0.2

Competition

When two species/populations require the same limited resource and have to compete for it

Predation

When one species kills another for food

What is a density-dependent limiting factor?

A factor that only limits a population depending on its size

What is a density INdependent limiting factor?

A factor that limits a population regardless of its size

What factors affected the Kaibab deer population?

Competition, starvation, overhunting

SPCEBB

Species, population, community, Ecosystem, biome, biosphere

How is energy used by organisms?

To generate body heat, to move, to maintain homeostasis

Energy is lost as

It passes through each trophic level

What are the reactants of photosynthesis?

6CO2, 6H20, and light

What are the products of Cellular respiration?

6C02, 6H20, 32-38 ATP

Steps of Aerobic Cellular Respiration

1. Glycolysis - breakdown of sugar - Cytoplasm

2. Kreb’s Cycle - Produces C02 - Mitochondria

3. Electron Transport Chain - Produces ATP - Mitochondrial Membrane

What piece of evidence tells us when oxygen was abundant in the atmosphere?

banded iron formations

What piece of evidence supports the idea that there were organisms producing oxygen?

Stromatolites

Where does the light dependent reaction take place?

Thylakoid

Where does the light independent reaction take place?

Stoma

Photosynthesis equation

6H20+6C02+LIGHT=C6H12O6+6O2

Cellular respiration equation

C6H1206+602=6H20+6CO2+32-38ATP

Formula for calculating volume of a cell

Length x Height x Width

Formula for calculating Surface area of a cell

Length x Width x Number of sides
