What is genetic diversity?

  1. The variety of genetic characteristics within a population.

  2. The number of different species in an ecosystem.

  3. The presence of different alleles for a gene.

  4. The amount of genetic material in an organism.


Correct Option: A
Explanation:

Genetic diversity refers to the variation in the genetic makeup of individuals within a population. It is important for the survival and adaptation of populations to changing environmental conditions.

How does air pollution affect genetic diversity?

  1. It can cause mutations in genes.

  2. It can reduce the number of individuals in a population.

  3. It can change the frequency of alleles in a population.

  4. All of the above.


Correct Option: D
Explanation:

Air pollution can affect genetic diversity in a number of ways. It can cause mutations in genes, which can lead to new alleles and changes in the frequency of alleles in a population. It can also reduce the number of individuals in a population, which can reduce genetic diversity. Additionally, air pollution can change the environment in ways that make it more difficult for certain species to survive, which can also reduce genetic diversity.

Which of the following is NOT a type of air pollutant that can affect genetic diversity?

  1. Nitrogen oxides

  2. Sulfur dioxide

  3. Ozone

  4. Water vapor


Correct Option: D
Explanation:

Water vapor is not an air pollutant that can affect genetic diversity. Nitrogen oxides, sulfur dioxide, and ozone are all air pollutants that can cause mutations in genes and other changes to the genetic makeup of organisms.

Which of the following is NOT a consequence of reduced genetic diversity?

  1. Increased susceptibility to disease

  2. Reduced ability to adapt to environmental changes

  3. Increased risk of extinction

  4. Increased productivity


Correct Option: D
Explanation:

Reduced genetic diversity can have a number of negative consequences, including increased susceptibility to disease, reduced ability to adapt to environmental changes, and increased risk of extinction. However, it is not associated with increased productivity.

Which of the following is an example of how air pollution can affect genetic diversity in plants?

  1. It can cause mutations in genes that control photosynthesis.

  2. It can reduce the number of stomata on leaves.

  3. It can change the color of flowers.

  4. All of the above.


Correct Option: D
Explanation:

Air pollution can affect genetic diversity in plants in a number of ways. It can cause mutations in genes that control photosynthesis, which can reduce the plant's ability to produce food. It can also reduce the number of stomata on leaves, which are small pores that allow for the exchange of gases. Additionally, air pollution can change the color of flowers, which can affect the plant's ability to attract pollinators.

Which of the following is an example of how air pollution can affect genetic diversity in animals?

  1. It can cause mutations in genes that control reproduction.

  2. It can reduce the number of offspring that an animal produces.

  3. It can change the color of an animal's fur or feathers.

  4. All of the above.


Correct Option: D
Explanation:

Air pollution can affect genetic diversity in animals in a number of ways. It can cause mutations in genes that control reproduction, which can reduce the animal's ability to produce offspring. It can also reduce the number of offspring that an animal produces. Additionally, air pollution can change the color of an animal's fur or feathers, which can affect the animal's ability to camouflage itself or attract mates.

What are some ways to reduce the effects of air pollution on genetic diversity?

  1. Reduce the use of fossil fuels.

  2. Plant trees and other vegetation.

  3. Use public transportation or walk instead of driving.

  4. All of the above.


Correct Option: D
Explanation:

There are a number of ways to reduce the effects of air pollution on genetic diversity. These include reducing the use of fossil fuels, planting trees and other vegetation, and using public transportation or walking instead of driving. These measures can help to reduce the amount of air pollution in the environment and protect the genetic diversity of plants and animals.

Why is genetic diversity important for the survival of species?

  1. It allows populations to adapt to changing environmental conditions.

  2. It reduces the risk of disease outbreaks.

  3. It increases the productivity of ecosystems.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity is important for the survival of species for a number of reasons. It allows populations to adapt to changing environmental conditions, such as climate change or the introduction of new diseases. It also reduces the risk of disease outbreaks, as it makes it less likely that all individuals in a population will be susceptible to the same disease. Additionally, genetic diversity increases the productivity of ecosystems, as it allows for a greater variety of organisms to fill different niches.

Which of the following is NOT a type of genetic diversity?

  1. Allelic diversity

  2. Nucleotide diversity

  3. Phenotypic diversity

  4. Behavioral diversity


Correct Option: D
Explanation:

Behavioral diversity is not a type of genetic diversity. Allelic diversity refers to the variation in alleles at a particular gene locus, nucleotide diversity refers to the variation in the sequence of nucleotides in a DNA molecule, and phenotypic diversity refers to the variation in observable characteristics of organisms.

Which of the following is an example of how air pollution can affect the genetic diversity of a population?

  1. It can cause mutations in genes.

  2. It can reduce the number of individuals in a population.

  3. It can change the frequency of alleles in a population.

  4. All of the above.
