Plantae
Protista
This organism is multicellular, heterotroph, that has a cell wall made of chitin.
animalia

Which of these is demonstrated by the information above?
The need for controlling variables by experiments.
The need for classifying and naming organisms scientifically.
The importance of predicting trends from scientific data.
The importance of questioning experimental evidence.
What is the importance of a standardized taxonomic system to the scientific community?
To have many different common names for one species.
To organize species' cells, tissues, organs, and organ systems
To have a universal scientific naming system and to avoid confusion
To analyze species genetic information
Which organism in the chart above is most distantly related from the other organisms?
A
B
C
D
What is the specimen number for the following insect?
Number 145
Number 256
Number 232
Number 123
What answers should you eliminate?
Obviously wrong answers
Choices that are partly wrong
Answers that are correct but don't answer the question
All of the above
A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called
Natural Selection
Selective Breeding
Random mutations
Variations in a species
If a sick person takes an antibiotic but it doesn't kill all of the bacteria causing the sickness, what might explain this?
Variations in the bacteria allowed some organisms to be less affected by the antibiotic
Bacteria cannot be killed by antibiotics
You cannot cure a bacterial infection
Bacteria do not cause sicknesses
Individuals can not evolve.
Which of the following is an example of the bottleneck effect?
Cheetah populations reach their lowest levels with reduced diversity and as they rebound are so genetically similar they appear to be inbred.
Affected individuals with blue skin can trace their ancestry back to one of the first settlers in the region.
The environment of a fox population changes and over time foxes who are white survive and pass on their genes to their offspring.
Humans choose two dogs they like the characteristics of and breed them together.
This mechanism of evolution occurs when individuals of one population migrate and mate with individuals of another population.
Extinction
Gene flow
Genetic drift
Natural Selection
A harmless scarlet king snake and a venomous eastern coral snake have similar band patterns, as shown below. For the scarlet king snake, the adaptation of having a banding pattern like the eastern coral snake’s is known as mimicry
The outcome of this adaptation in the scarlet king snake is to —
make it easier for the scarlet king snake to attract prey
make it easier for the scarlet king snake to interbreed with the other snake
allow the scarlet king snake to blend in with its environment
protect the scarlet king snake from predators
Adaptations that result from natural selection are expected to increase the fitness of an organism. In terms of natural selection, which of the following best describes fitness?
Being able to escape from predators
Being among the strongest organisms in a population
Being able to survive, find a mate, and produce offspring
Being able to survive long enough to reach the adult stage
Does gene flow increase or decrease the genetic variety/diversity of a population?
Increase
Decrease
Who first proposed binomial nomenclature as a way of classifying organisms?
Carolus Linnaeus
Aristotle
Charles Darwin
Louis Pasteur
Who is going to ACE the Evolution exam?

No one
