Species are classified based on their characteristics. Which characteristic identifies two organisms as members of one species? The organisms
can produce fertile offspring.
can communicate easily.
will defend their territory.
will move from place to place.
The table below shows the classification of four organisms. Which two are most related in terms of their DNA and evolutionary history?
Shark and Wolf
Whale and Wolf
Whale and Shark
Shark and Grasshopper
How do dichotomous keys and phylogenetic trees differ in regards to the information they provide?
Dichotomous keys concentrate on evolutionary relationships, while
phylogenetic trees are used to classify organisms by similar and
dissimilar traits.
Phylogenetic trees concentrate on evolutionary relationships, while
dichotomous keys are used to classify organisms by similar and
dissimilar traits.
Dichotomous keys provide information about ancestors of species,
and phylogenetic trees help identify specific species by using
observable traits.
Phylogenetic trees, also called pedigrees, provide a family history,
while dichotomous keys help identify members within a family.
The table is a dichotomous key.
If an organism with straight antennae and stripes on the middle segment is found, which organism group would it most likely belong to?
Organism A
Organism B
Organism C
Organism D

conditioned behavior
imprinted behavior
territorial behavior

The flower of an Australian orchid resembles a female wasp, which can attract male wasps. Which adaptation is exhibited by the orchid that helps with its reproduction and survival?
mimicry
behavioral
camouflage
protective coloration
A crop was treated with a pesticide and 98% of the insects were killed. Which is the most likely reason that 2% of the insects survived?
They were shielded by the crops while the pesticide was being
applied.
They migrated to the area after the crops were treated with the
pesticide.
They contained the genes that allowed them to be resistant to the
pesticide.
They developed the trait to be resistant to the pesticide after it was
applied.
Which is true concerning evolution?
Evolution occurs in a population in one generation.
Evolution occurs in an individual in one generation.
Evolution occurs in a population in several generations.
Evolution occurs in an individual in several generations.
According to the Theory of Natural Selection, which is the ultimate goal of any organism?
live an easy life
build tolerance to diseases
become the strongest organism
reproduce to pass on traits to the next generation
On the Galapagos Islands, Darwin found seven different species of finches that he believed began as one species. Which best explains the evolution of these bird species?
Finches adapted with a change in the shape of their beak because of local food sources.
Finches were bred to other bird species, which created new species.
Sailors brought in finches that were related to the finches on the
islands.
Finches changed their traits genetically as they adapted to the new
climate.
A population of rabbits becomes separated by a river. Over thousands of years, rabbits on different sides of the river become genetically different
and evolve into different species that do not look alike. Which mechanism of evolution has most likely occurred?
species isolation
geographic isolation
reproductive isolation
evolutionary isolation
How do scientists explain the increase in oxygen in Earth’s early atmosphere?
Microbes produced oxygen through photosynthesis.
Ozone was dissolved, creating free oxygen in the atmosphere.
Greenhouse gas molecules were separated into atmospheric oxygen.
Water condensed as the Earth cooled, creating water-filled
depressions.
Over time an antibiotic will no longer be effective on some bacteria. What is the most likely reason for this?
Humans have built up a resistance to the bacteria.
Humans have built up a resistance to the antibiotic.
The surviving bacteria are resistant to the antibiotic.
The antibiotics have become resistant to the bacteria.
How does the fossil record support the theory of evolution?
by showing physical evidence that all organisms develop in similar
ways
by showing embryonic similarities between extinct and present-day
organisms
by providing evidence for the missing gaps in Earth’s history for all
living organisms
by providing evidence that extinct species have similar traits to
present-day organisms
Examine the phylogenetic tree below.
Which 2 organisms are most closely related?
sponges and placozoa
worms and arthropods
echinoderms and chordates
hemichordata and echinoderm
