Two allopatric species of sparrows have very similar niches when compared to two sympatric species of sparrows. What would be a good explanation for this?

The allopatric species have no competition with one another so therefore can occupy similar niches

The sympatric species are usually mechanically isolated from one another

The sympatric species diverged from a common ancestor

The allopatric species are behaviorally isolated from one another

which of the following is not involved in natural selection?

differences in reproductive success

inheritable variation in populations

divergence of two or more species from an existing one

combining of tow species to form one with different traits

isolation that affects mating behaviors

timing of mating that prevents normal sexual selection

What is suggested by the similarity of early embryos of different species of vertebrates?

evolution from a distant common ancestor

no evolutionary relationships between the groups

similar environments in the past

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

Which of the following statements is correct based on the information shown in this cladogram?

the turtle and the frog are more similar to each other than the turtle and the bass

frogs have existed for a longer time that bass

the frog is more closely related to the bass than to the leopard

Which of the following evolutionary forces can introduce new genetic variation into a population?

natural selection and non-random mating

natural selection and genetic drift

A mutation occurs in a particular animal and quickly begins to increase in frequency throughout the population. Which of the following are you most likely to conclude?

The mutation increase the probability that the animal will reproduce.

The mutation makes the animal grow larger

The mutation does not confer any benefit or harm to the animal

The mutation makes the animal more susceptible to predators

Which of the following is an example of gene flow?

A young stallion is driven out of its herd by the alpha stallion and begins its own herd in another location

A subordinate wolf successfully challenges the alpha male and mates with pack females

A deer picks up spores from a plant as it grazes and deposits them next to that plant.

All of the following should be used to construct evolutionary trees EXCEPT

morphological similarities and differences

What explains the inclusion of rabbits?

they are the most recent ancestor of primates

they have a short generation time and are easy to study

they possess shared derived characteristics of the included species

Which statement correctly explains how resistance to penicillin appeared after a few years of its widespread use to fight bacterial infection?

some bacteria were resistant to penicillin and their population spread rapidly, without competition from bacteria that were killed by penicillin

in order to survive exposure to penicillin, bacteria developed a resistance to the drug

a few bacteria became resistant to penicillin, and through sexual reproduction , most bacteria acquired the resistance

penicillin never really successfully wiped out populations of bacteria, scientist did not use proper controls in their studies

A group of organisms that can mate with each other and produce fertile offspring.

A group of organisms that genetically are very different from each other.

A group of organisms that can mate and produce offspring even if those offspring are infertile.

Indivual organisms that live in the same environment.

Scientists find that most feral cats in a neighborhood have whiskers about 12 cm long. After about 15 generations of stabilizing selection, what would you expect to see?

even more cats with 12 cm long whiskers

most cats with less than 12 cm long whiskers

most cats with more than 12 cm long whiskers

most cats with whiskers either less than or more than 12 cm long, very few with whiskers 12 cms

Miller/Urey and other scientists have shown that:

Amino acids could be produced from inorganic molecules

Life on early Earth required material from space

Cells survived in the primitive atmosphere

Simple cells can be produced in a laboratory

Why do some scientists believe that RNA, rather than DNA, was the first genetic material?

RNA has both information storage and catalytic properties.

RNA can replicate more accurately than DNA.

RNA contains uracil in place of thymine.

RNA World Theory states that ...

Life came from non living things

What are 'protobionts'?

A collection of organic molecules surrounded by a lipid membrane

Complex catalysts that existed on early Earth

The diagram shows fossils in different rock layers. Which of these statements about the age of these fossils is most likely correct?

Fossil D is older than fossil C

Fossil A and C are the same age

Fossil B is older than fossil C

Fossils A is older than fossil B

Which type of cell came first?

Both Eukaryotic and Prokaryotic cells evolved around the same time
