Evolution and Natural Selection

What is the Peppered moth an example of in the context of natural selection?

• Disruptive selection

• Stabilizing selection

• Directional selection

• Sexual selection

How did the color of the Peppered moth change due to natural selection?

• From a dark to light color

• From a light to dark color

• From a green to brown color

• From a brown to green color

What was the impact of the industrial revolution on the lichens in the context of the peppered moth's habitat?

• It promoted the growth of lichens.

• It had no significant impact on lichens.

• It killed the lichens, exposing the dark tree bark.

• It changed the color of the lichens to darker shades.

What is the primary reason that alleles for antibiotic and pesticide resistance may already exist in a population before the application of these substances?

• They are introduced by external environmental factors.

• They are artificially inserted into organisms by scientists.

• They can be introduced by mutation.

• They are always present in all individuals.

What happens when antibiotics or pesticides are applied to a population where resistant alleles exist?

• The application increases the mutation rate in the population.

• Susceptible individuals are eliminated, allowing non-susceptible individuals to reproduce without competition.

• All individuals, regardless of their genetic makeup, are eliminated.

• The population size dramatically increases due to enhanced reproduction rates.

What type of immunity is developed when antibodies are produced within the person's body after exposure to a pathogen?

• Passive natural immunity

• Active artificial immunity

• Active natural immunity

• Passive artificial immunity

Which type of immunity is characterized by the introduction of antibodies from another organism into a person's body?

• Active natural immunity

• Active artificial immunity

• Passive natural immunity

• Passive artificial immunity

How is artificial active immunity typically acquired?

• Through natural infection

• By receiving pre-formed antibodies

• By vaccination

• Through genetic inheritance

What is an example of natural passive immunity?

• Vaccination for influenza

• Antibodies crossing the placenta from mother to fetus

• Recovery from a bacterial infection

• Injection of anti-tetanus antibodies

What is speciation as described in the learning material?

• A) The process of a species moving to a new habitat

• B) The division of one species into two due to geographic isolation

• C) The formation of new species

• D) The extinction of a species
