A population of bacteria is treated with antibiotics. What are the possible outcomes for the surviving bacteria?
The population will grow quickly
All of the bacteria are going to be resistant.
The bacteria will become endangered.
Some may be resistant and survive
One of the biggest ways that a species evolves is because some organisms with some traits survive and reproduce better than others.
Natural Selection
Coevolution
Convergent Evolution
Sexual Selection
Genes for traits that help an organism be more successful in mating can expect to
cause it to evolve into a new species
become more common in the future
cause the extinction of the species
eventually be eliminated by natural selection
An adaptation is
any trait an organism possesses
how an organism evolves during its own lifetime
a gene an organism has
a trait that helps an organism survive in its environment
Genetic diversity is ultimately/mainly the result of
meiosis
viruses
mutations
reproduction
Which of the following is not an example of evolution
horses becoming taller and faster over millions of years
all species of turtles in America coming from the same anceser
Human jaws shrinking over time
A caterpillar going through a change into a moth
Which of the following does not increase genetic variation?
Mutatuins
Gene flow
Mitosis
Crossing Over
Which of the following is not a principle of natural selection
Most species produce more offspring than will actually reproduce
organisms compete for limited resources
evolution will occur as an organism gets older and learns more
Individuals that are well adapted to their environment will survive and produce ____.
Fewer mutations
more offspring
stronger genes
better traits
Natural selection results in change over time by acting on traits that are ___.
heritable
new
mutated
better
Organisms that live in similar environments such as the ocean often have similar adaptations. This is often due to
convergent evolution
coevolution
gradualism
sexual selection
Which pattern of evolution results in one species splitting in to many over time?
Coevolution
Divergent Evolution
Convergent evolution
Sexual Selection
If scientists wanted to learn more about evolution by studying biochemistry, they would study
Lipids (fats)
DNA
Carbs
Macromolecules
Scientists can explore whether two different animal species have evolved from a common ancestor by using evidence from
comparison of the experiences of each organism
studies of embryos during development
discussing the conversations the animals have had.
Gibbons and Fetal Pigs
Two bodily structures, found in different species, have different internal bone structures but serve similar purposes.
Homologous Structures
Vestigial Structures
Analogous Structures
Natural Selection
Whales have bones for rear legs but do not walk. This is an example of
Homologous Structures
Vestigial Structures
Analogous Structures
Natural Selection
Evidence of evolution from the field of paleontology exaqmines
fossils compared to living species
embryos of different species
Sequences of DNA
The locations of gene on the DNA
Fossil evidence shows that structures considered vestigial in living organisms
were useful to their ancestors
are not found in ancient organisms
have always been vestigial
do not fill in gaps in the fossil record
According to binomial nomenclature, species are given two names based on their
kingdom and species
genus and species
class and phylem
order and genus
