QUIZ
1. What is coevolution referred to when it involves just two species evolving with each other?
Advertisement
a. Guild coevolution b. Diffuse coevolution c. Parasitic coevolution d. Specific coevolution
Answer: d. Specific coevolution or pairwise evolution is the evolution together of just two species with each other.
2. What other species of organisms is mutualistic and has coevolved with honeybees?
a. Ferns b. Flowering plants c. Mosquitos d. Deciduous trees
Answer: b. Honeybees have evolved together with flowering plants because they have developed a mutualistic relationship with one another.
3. What happens if a virus is too aggressive to humans and kills the hosts entirely?
a. The viruses will become overpopulated in the world. b. The viruses will die off for lack of hosts. c. The viruses will eventually mutate to be less infectious. d. The viruses will occupy a different host.
Answer: b. If a virus is too virulent or aggressive so that they kill off the hosts, they will not generally be able to mutate fast enough to find another host and will die off themselves. They do not have the ability to survive long outside the host and cannot overpopulate the earth.
4. What is the major evolutionary contribution of the coevolution of hosts and parasites?
a. The development of sexual reproduction b. The development of the innate immune system c. The development of the adaptive immune system d. The development of mutualism between two species
Answer: a. It is believed that sexual reproduction developed in evolution because of host-parasite relationships that allowed for the better ability to fight off parasitic disease by the host s offspring.
5. What are moths least likely to do in order to avoid getting eaten by bats?
a. They have erratic flight patterns when there is echolocation. b. They make their own clicking sounds to confuse echolocation. c. They jam sonar signaling. d. They have evolved thin wings that cannot be picked up through echolocation.
Answer: d. The moths do each of these things to confuse the bats but they do not have thin wings that cannot be picked up through echolocation.
6. Which is an example of a mutualistic relationship between two organisms?
a. Honeybees and flowering plants b. Cheetahs and gazelles c. Snakes and mice d. Moths and bats
Answer: a. The relationship between honeybees and flowering plants is mutualistic because both members benefit from the relationship. The rest of the relationships are predator-prey relationships.
7. The dispersal of seeds by animals in nature is referred to as what?
a. Zoochory b. Cleaning symbiosis c. Service-resource symbiosis d. Parasite-host relationship
Answer: a. Zoochory is when seeds are eaten by animals or when fruit is eaten by animals, who then pass on the seeds through dispersal in the environment.
a. A parasite provides disease resistance to the host b. Two species protect each other from predators c. An organism secretes a substance that is taken up by the host organism d. A predator is prevented from eating all of the animals in a herd
Answer: b. When two species protect each other from predators, this is called a service-service symbiotic relationship. The relationship between clownfish and sea anemones is like this.
9. Which disease state has a heterozygote advantage in certain populations?
a. Muscular dystrophy b. Cystic fibrosis c. Myasthenia gravis d. Sickle cell anemia
Answer: d. Patients with sickle cell anemia have a heterozygote advantage because being a heterozygote will confer resistance to malaria, which is not the case with homozygotes.
10. What two organisms coevolve in antagonistic coevolution?
a. Parasites and hosts b. Males and females of the same species c. Competing species who use the same resources d. Mutualistic species
Answer: b. Males and females of the same species will have antagonistic coevolution with each other.
