Fossils of organisms or their tracks provide evidence of the number and type of organisms in an environment. What would cause a drastic reduction in fossils in different layers of a geological area of study?

• Low competition for food

• Extinction of species

• Favorable environmental conditions

• Evolution of individuals from terrestrial to aquatic environments

A queen honeybee can lay up to 2,000 eggs in one day. This is an example of overpopulation. One benefit to laying so many eggs is to-

• increase competition among honeybees for finding nectar

• increase the chance of honeybees to survive and repoduce

• increase the amount of honey produced for human consumption

• decrease competition among honeybees so bumblebees can share resources

Okapi are strange animals that look like a combination of a giraffe and a zebra. They live in the Democratic Republic of Congo, where it's very hot and predators, such as leopards, are always lurking. The okapi use their 14-18 inch-long tongues to wash their eyes and ears to better see and hear the leopards in the dry, sandy environment. The features of the okapi are evidence of natural selection because the adaptation -

• causes an increased rate of extinction due to eye infections

• shows DNA mutations do not increase the survival of organisms with variations

• helps individuals compete for survival to pass down traits through their DNA

• creates a disadvantage which decreases the organisms chances for survival

Fawns, baby deer, usually are weaned at two to three months of age. In early autumn, a fawn's spotted coat is replaced by the gray-brown winter coat of an adult deer. Female fawns usually stay with their mothers for two years; young bucks leave after a year. Which of these is a likely outcome when young bucks leave their mothers?

• Intermediate phenotypes increase in the species

• Allele frequencies suddenly change

• Gene flow occurs between population

• Spotted coat returns as dominant phenotype

what did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

• different species on different islands

• all species on one of the islands

• identical species on all the islands

• the same species as North America

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• Hardey-Weinberg equilibrium within a population

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the trait is an acquired phenotype.
