Example Questions
Example Question #21 : Identify Evolutionary Change Mechanisms
Which of the following best defines apparent competition?
Direct competition between individuals through aggression
Indirect competition between two species hunted by the same predator
Members of the same species compete for the same resource
Indirect competition through a limiting resource
Indirect competition between two species hunted by the same predator
Apparent competition is defined as indirect competition between two species being hunted by the same predator.
Example Question #22 : Identify Evolutionary Change Mechanisms
Which of the following is not an example of intraspecific competition?
Flamingoes fighting for mates
Organisms of one species of grass competing for sunlight
Two species of grass competing for sunlight
Two male red deer fighting for mates
Two species of grass competing for sunlight
Intraspecific competition is a type of competition that occurs between individuals of the same species. All of the given examples feature intraspecific competition except “two species of grass competing for sunlight,” because it describes competition between two species instead of within the same species.
Example Question #23 : Identify Evolutionary Change Mechanisms
Which of the following best describes the difference between intraspecific and interspecific competition?
Interspecific competition is a type of competition within the same species and intraspecific competition is a type of competition between different species
Interspecific competition is a type of competition between different species and intraspecific competition is a type of competition within the same species
Intraspecific competition encompasses interspecific competition
Intraspecific competition is only indirect while interspecific competition cannot be indirect
Interspecific competition is a type of competition between different species and intraspecific competition is a type of competition within the same species
Intraspecific competition occurs between members of the same species while interspecific competition occurs between different species.
Example Question #282 : Evolution And Genetics
Which of the following is not a mechanism of evolution?
Sexual reproduction
Gene flow
Genetic drift
Mutation
Sexual reproduction
The mechanisms of evolution include gene flow, mutation, genetic drift, and natural selection. All of these mechanisms change allele frequencies in groups of reproducing organisms.
Example Question #24 : Identify Evolutionary Change Mechanisms
Which of the following is an example of exploitative competition?
Flour beetles eating the eggs of a competitor species of flour beetle
Lions chasing hyenas away from their prey
Two species of grass competing for sunlight
Caterpillars physically intimidating other caterpillars of the same species to guard leaf surface area
Two species of grass competing for sunlight
Exploitative competition is an indirect type of competition through a limiting resource. There was only one scenario in the listed options that illustrated an example of exploitive competition: the indirect competition that takes place in response to a limiting resource as seen in grass species competing for sunlight.
Example Question #25 : Identify Evolutionary Change Mechanisms
Which of the following statements best describes co-evolution?
Beneficial interactions between species
The dying out of a species
Process in which a species diverges into two distinct species
Interactions between species
Interactions between species
Co-evolution describes interactions among different species. These interactions can be both negative and positive, leading to cooperation or competition. In co-evolution, species develop together.
Example Question #26 : Identify Evolutionary Change Mechanisms
Which of the following is not true regarding extinction?
Extinction is the dying out of a species
Extinction is well-understood in the scientific realm
The majority of extinctions are minor
Throughout history there have been both mass and minor extinctions
Extinction is well-understood in the scientific realm
Extinction may be defined as the disappearance of a species. Throughout history, there have been minor and major extinctions, with minor extinctions composing the majority of all extinctions. The process of extinction is not well understood due to our reliance on the fossil record and complicated roles of competition and evolution.
Example Question #27 : Identify Evolutionary Change Mechanisms
Which of the following is not true regarding adaptation?
It is produced by natural selection
They result in the divergence of species
It makes an organism better suited to live in a given habitat
They increase the chance of survival and reproduction
They result in the divergence of species
Adaptation can be defined as the gradual outcome of evolution that makes an organism or group of organisms better suited to live in a given habitat. Adaptation is a result of natural selection and increases the chance of survival and reproduction. This outcome can result from either a loss of an ancestral feature or the development of a new trait.
Example Question #1923 : Ap Biology
Which of the following is a potential outcome of the evolutionary process?
Adaptation
Extinction
Speciation
All of these
All of these
Evolution impacts the allele frequencies within a population through mutation, genetic drift, gene flow, and natural selection. These mechanisms of evolution result in adaptation, cooperation, speciation, extinction, and co-evolution.
Example Question #28 : Identify Evolutionary Change Mechanisms
Which of the following is true in regard to cooperation?
One species evolves independently
Kin selection directly opposes cooperation
Cooperation involves beneficial interactions between species
It involves only conflict between species
Cooperation involves beneficial interactions between species
Cooperation is an outcome of evolution that features beneficial interactions between species, leading to the species evolving together. Cooperation is thought to have evolved from kin selection—where organisms work together to raise another’s kin for the benefit of the population.
