NS Test review

The diagram shows light- and dark-colored beetles that live on a tree. Which result is most likely to occur to the beetle population due to predation over time?

• The number of light-colored beetles in the population will increase.

• There will be more dark-colored beetles than light-colored beetles.

• The number of light-colored beetles will decrease.

• The dark-colored beetles will move to a different type of tree.

The table shows the survival rate of two types of beetles in the same environment over a period of three years.  

Which statement about the beetles in this environment is best supported by the data?

• Brown beetles have a shorter life cycle than green beetles have
• Green beetles are more fit for their environment than brown beetles
•  brown beetles are undergo more unfavorable mutations than green beetles

Adaptations that result from natural selection are expected to increase the fitness of an organism. In terms of natural selection, which of the following best describes fitness?

• Being able to escape from predators

• Being among the strongest organisms in a population

• Being able to survive, find a mate, and produce offspring

• Being able to survive long enough to reach the adult

In the 1940s, the scientist J. B. S. Haldane linked many human red blood cell disorders with the tropical regions where malaria occurs. Haldane hypothesized that the widespread presence of these red blood cell disorders as well as traits that protect individuals from malaria were the result of natural selection. Haldane’s hypothesis was later confirmed by the research of A. C. Allison.

The resistance to malaria carried by individuals in areas where malaria is widespread is the result of —

• a vaccine against malaria

• the individuals’ genetic composition

• antibiotic medications

• the individuals’ behavior in avoiding those with the infection

Nudibranchs are marine gastropods that lack shells. Many of these gastropods retain the foul-tasting poisons of their prey and secrete them when threatened. The bright coloration of the nudibranchs warns predators to avoid them.

Based on this information, how has adaptation allowed marine gastropods to be successful without a shell?

• They find enough food as they move through the marine environment.

• They blend in with their environment to hide from their predators.

• They are not attacked by most predators and are able to reproduce successfully.

• They have bright colors that attract a mate.

The white cattail is a hybrid species of plant that is a result of the cross between the broad-leaved cattail and the narrow-leaved cattail. Over time, the white cattail has established itself in the wetlands of Midwestern states.

Which of these explains the success of the white cattail?

• Favorable genes from parental generations provide advantageous characteristics to the hybrid species.

• Hybridization produces offspring traits that allow different species to survive in extreme environments

• Inherited traits passed on from parental generations make hybrid species more susceptible to disease.

• Hybrid species display more adaptations due to their reduced genetic diversity

Common baboons live on the savanna in breeding groups called troops. While females tend to stay with the troop, younger or less dominant males may leave to join a neighboring troop. Which of these is a likely outcome of movement by young males?

• Gene flow occurs between populations.

• Allele frequencies suddenly change.

• Relative genotypic frequencies reach a constant state.

• Intermediate phenotypes increase in the species.

Researchers studying populations of lizards from the genus Gallotia on the Canary Islands compared the protein cytochrome b in different populations. The table shows the number of differences in the cytochrome b protein between different populations.

Which conclusion about the relatedness of the lizards do these data support?

• G. atlantica and G. stehlini are the least closely related.

• G. simonyi and G. bravoana are the most closely related.

• G. galloti eisentrauti and G. galloti palmae are the most closely related.

• G. galloti eisentrauti and G. galloti galloti are the least closely related.

California king snakes may exhibit different patterns of stripes. According to

evolution by natural selection, which of the following is the most likely result if a

snake-eating predator can more easily detect the snakes with the crosswise

stripes?

• The percentages of snakes born of each type will not change.

• Snakes with lengthwise stripes will become more common.

• Snake with crosswise stripes will learn to move faster.

• A new type of kingsnake with no stripes will emerge.

A population of mice displays coat color varying from light to dark. A group of researchers report that they have identified several mutations in a gene that seem to be responsible for the color differences. Over time, how might natural selection result in a difference in reproductive success of members of the mice population?

• Light-coated mice and dark-coated mice are equally preyed upon by owls.

• Mice with coat color better adapted to their environments survive and reproduce.

• Dark-coated mice migrate of the population to avoid the light mice

• Light-coated and dark-coated mice produce equal numbers of offspring.
