Apple farmers are currently having a very difficult time with pesticide-resistant insects. These insects are no longer being killed by the current chemical treatments, thus causing a lot of damage to the apple crops. In reaction to this, researchers are developing newer and stronger chemicals to help control the bugs.
Why are the apple farmers seeing these new, stronger bugs?
The bugs were not native to the area and thus cannot be killed by normal chemicals.
Changes in the weather have led to stronger insects that can survive these harsh changes.
The strongest bugs were able to survive pesticides, reproduce and create more resistant pests.
The apple trees are producing too many apples, which is allowing the insects to reproduce rapidly.
A wide number of antibiotics have been created today to treat bacterial infections. Antibiotics have been greatly effective in treating many diseases. An unintended negative side effect of the development of antibiotics is that
people recover faster from infections.
antibiotics cannot treat viral infections.
overuse has contributed to the rise of new resistant bacteria.
there are a large number of different antibiotics available today.
Which of the following is not an evidence for microevolution?
increasing (large) population
mutations occur
non-random mating
gene flow
Which observation BEST supports evidence that two different species share a common ancestor?
they both prey on the same animals for food
they both burrow into the ground for shelter
they both have similarities in early embryonic development
they both share similar biochemical pathways for energy production
The wings of ostriches are examples of vestigial structures. The wings provide evidence for which of these evolutionary relationships?
A new bird species without wings will evolve from ostriches.
A new bird species that has useful wings will evolve from ostriches.
An ancestor of ostriches had useful wings.
An ancestor of ostriches had vestigial structures.
Which of these statements BEST defines vestigial organs?
vital organs that are functional in all organisms of a lineage
vital organs that are functional only in alternate generations of a lineage
redundant organs present in an organism, which have been functional in the organism’s ancestors
redundant organs present in an organism, which will be functional in the succeeding generations of the lineage
If scientists wanted to learn more about evolution by studying biochemistry, they would study all of the following EXCEPT
DNA
nucleic acids
proteins
lipids (fats)
Two bodily structures, found in different species, have different internal bone structures but serve a similar purpose in each organism. This is most likely describing
homologous structures
vestigial structures
analogous structures
natural selection
Antibiotics would be effective against
bacterial pneumonia
the malaria protist
the flu virus
viral meningitis
Which of the following statements about phylogenetic trees is not true?
They can show which groups of organisms are most closely related.
They can show which groups of organisms are more advanced than other groups.
They can show which group of organisms diverged longest ago.
They can show predictions of evolutionary relationships from the analysis of shared heritable traits.
Skeletal structures are common between two different animal species. These structures probably exist because both species...
have a common food source
live in the same environment
have survived until the present time
are related to a common ancestor
Study the cladogram. Which two organisms would be the least related?
hamster and salmon
lizard and salamander
chimpanzee and salmon
chimpanzee and hamster
Flowering plants are also vascular plants. Based on the cladogram, what other members of the kingdom Plantae also have vascular tissue?
clubmosses
ferns
quillworths
spikemosses
Early during development, organisms as diverse as a human, a mouse, and a bat can appear indistinguishable. All of their embryos look nearly identical, suggesting that
during development, humans go through stages of being a mouse and a bat.
similar structures have developed because of convergent evolution.
these very different species have a shared ancestry with all mammals.
this is a coincidental resemblance between them.
Artificial selection has produced a wide variety of crop plants, livestock, and pets. Which characteristic of artificial selection makes it different from natural selection?
Humans, not the environment, select which organisms survive and reproduce.
Adaptations develop gradually over many generations.
The stock that are reproduced are genetically identical.
All offspring are allowed to survive and reproduce.
