In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
convert the DNA into gel
cut the DNA into fragments
change the color of the DNA
produce longer sections of DNA
A student performed a gel electrophoresis experiment. The results are represented in the diagram
below. Compared to the fragments at the top of the gel, the fragments at the lower end are
larger, and move slower
larger, and move faster
smaller, and move faster
smaller, and move slower
This technique used to analyze DNA involves the
synthesis of new DNA strands from subunits
separation of DNA fragments based on size
production of genetically engineered DNA molecules
removal of defective genes from DNA
have the ability to interbreed.

The light mice can reproduce more successfully than the dark mice
The hawks eat more dark mice than light mice because the dark mice taste better
The hawks eat more light mice than dark mice because they can see the light mice more easily
The hawks eat more dark mice than light mice because they can see the dark mice more easily
Before the industrial revolution the birds were eating more black moths. After the industrial revolution the birds started eating more white moths. Why
The birds thought the white moths tasted better.
There were not any black moths to eat
The white moths stood out on the dark trees so the birds could see them easier.

Point A
Point B
Point C
Point D
What is the purpose of a cladogram?
To map the ancestral relationships and shared traits of different organisms.
To trace the inherited traits of a single species over time.
To check the likelihood of an offspring having a particular trait.
To monitor mutations that arise among different populations.

Which type of growth is best illustrated by this rabbit population?
exponential
logistic
S-shaped
predator-prey
According to the graph, what is causing the deer population to decrease
They got sick
The wolf population is decreasing
The wolf population increased
They ran out of food
Predator population lags behind prey population because......
Increase in predators leads to decrease in prey
Increase in predators leads to increase in prey
Increase in predators leads to decrease in producers
Increase in producers leads to increase in prey
All energy in an ecosystem comes from the sun. This energy is passed through the ecosystem as organisms eat other organsims.
Ominvores
Herbivores
Detritivores
Flow of energy
The level in an Ecological pyramid that includes all the organisms that share the same place in a food chain.
Trophic Levels
Toxic Levels
KeKe Levels
Environmental Systems
Only 10% of the energy is passed on from one trophic level to the next. 90% is lost as heat due to cellular respiration or waste.
Tertiary Consumer
Biotic Factor
Abiotic Factor
10% Rule
If there are 50,000 Joules of Energy available at the producers level, how much will available in secondary consumer trophic level?
5000 Joules
5 Joules
50 Joules
500 Joules
A consumer that eats only producers or plants, usually a primary consumer.
Herbivore
Carnivore
Omnivore
Decomposer
