Multiple Choice

When antibiotics were first developed, most infectious diseases could be controlled by them.  Today, certain bacteria are resistant to many antibiotics. One possible explanation for this change is that

• the antibiotics only killed the weaker bacteria or ones that did not have a genetic variation for resistance

• the bacteria needed to change in order to produce more antibiotics

• some of the bacteria learned how to resist the antibiotics

• antibiotics have become weaker over the years

Multiple Choice

Scientists discover that cells from two species of organisms are made up of similar proteins, suggesting a close evolutionary relationship. If the scientists do further biochemical analyses, which additional finding would support this conclusion?

• The fossils of both organisms are found relatively close to each other in the fossil record

• The anatomical structure of both organisms is similar

• The DNA nucleotide sequences of both organisms are very similar

• Both populations of organisms have undergone natural selection over time

Multiple Choice

The chart shows vertebrate embryo development. Which of these 4 organisms would be least related to the others?

• Fish

• Turtle

• Chicken

• Humans

Multiple Choice

A flock of one species of birds arrives on a group of sparsely populated islands. With little or no competition, different species of birds evolve from the original species. Each species is adapted to a different available niche. This is an example of

• Divergent Evolution

• Convergent Evolution

• Dynamic Equilibrium

• Graduation Equilibrium

Multiple Choice

Cross-pollination of flowers from different populations of the same species will most likely result in- 

• gene flow as new alleles are introduced from one population into another

• evolution of a different species as alleles mix

• hybrid sterility as gametes from different individuals are incompatible

• a decrease of genetic variation among individuals

Multiple Choice

Genetic drift states that the random effects of everyday life can cause differences in the survival and reproduction of individuals. What is one effect of genetic drift on evolution?

• It produces only the traits in a population that are best adapted to the environment

• It can cause an unusual amount of genetic variation within a single population of a species

• It can cause a population’s allele frequencies to stay in genetic equilibrium

• It can cause unfavorable traits in a population to increase by chance
