What is genetic diversity?

  1. The variety of genetic material within a population or species.

  2. The number of different species in an ecosystem.

  3. The process by which new species are formed.

  4. The study of how genes are passed from parents to offspring.


Correct Option: A
Explanation:

Genetic diversity refers to the variation in the genetic makeup of individuals within a population or species. It is a measure of how different the genes are among individuals in a population.

Why is genetic diversity important?

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

  2. It increases the likelihood that some individuals will survive a disease outbreak.

  3. It makes populations more resistant to pests and diseases.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity is important because it allows populations to adapt to changing environmental conditions, increases the likelihood that some individuals will survive a disease outbreak, and makes populations more resistant to pests and diseases.

What are some threats to genetic diversity?

  1. Habitat loss and fragmentation.

  2. Pollution.

  3. Climate change.

  4. Inbreeding.


Correct Option:
Explanation:

Genetic diversity is threatened by a number of factors, including habitat loss and fragmentation, pollution, climate change, and inbreeding.

How can we protect genetic diversity?

  1. Conserving natural habitats.

  2. Reducing pollution.

  3. Mitigating climate change.

  4. Promoting sustainable agriculture.


Correct Option:
Explanation:

We can protect genetic diversity by conserving natural habitats, reducing pollution, mitigating climate change, and promoting sustainable agriculture.

What is the relationship between genetic diversity and industrialization?

  1. Industrialization can lead to a loss of genetic diversity.

  2. Industrialization can promote genetic diversity.

  3. Industrialization has no effect on genetic diversity.

  4. The relationship between industrialization and genetic diversity is unknown.


Correct Option: A
Explanation:

Industrialization can lead to a loss of genetic diversity through habitat destruction, pollution, and the introduction of invasive species.

How does industrialization lead to a loss of genetic diversity?

  1. By destroying natural habitats.

  2. By polluting the environment.

  3. By introducing invasive species.

  4. All of the above.


Correct Option: D
Explanation:

Industrialization can lead to a loss of genetic diversity by destroying natural habitats, polluting the environment, and introducing invasive species.

What are some examples of how industrialization has led to a loss of genetic diversity?

  1. The destruction of rainforests for agriculture.

  2. The pollution of rivers and lakes with industrial chemicals.

  3. The introduction of the cane toad to Australia.

  4. All of the above.


Correct Option: D
Explanation:

Industrialization has led to a loss of genetic diversity through the destruction of rainforests for agriculture, the pollution of rivers and lakes with industrial chemicals, and the introduction of the cane toad to Australia.

What are the consequences of a loss of genetic diversity?

  1. Populations become more vulnerable to disease.

  2. Populations become less able to adapt to changing environmental conditions.

  3. Populations become more likely to go extinct.

  4. All of the above.


Correct Option: D
Explanation:

A loss of genetic diversity can have a number of negative consequences, including making populations more vulnerable to disease, less able to adapt to changing environmental conditions, and more likely to go extinct.

What can be done to mitigate the negative effects of industrialization on genetic diversity?

  1. Conserving natural habitats.

  2. Reducing pollution.

  3. Controlling the spread of invasive species.

  4. All of the above.


Correct Option: D
Explanation:

The negative effects of industrialization on genetic diversity can be mitigated by conserving natural habitats, reducing pollution, and controlling the spread of invasive species.

What are some examples of how industrialization can promote genetic diversity?

  1. By creating new habitats for species.

  2. By introducing new species to an area.

  3. By increasing the rate of mutation.

  4. None of the above.


Correct Option: D
Explanation:

Industrialization typically leads to a loss of genetic diversity, not an increase.

Which of the following is NOT a factor that can contribute to the loss of genetic diversity?

  1. Habitat destruction.

  2. Pollution.

  3. Climate change.

  4. Selective breeding.


Correct Option: D
Explanation:

Selective breeding is a process by which humans breed animals or plants with desirable traits, which can lead to an increase in genetic diversity, not a decrease.

Which of the following is an example of how industrialization can lead to the loss of genetic diversity in a natural population?

  1. The introduction of a new species to an area.

  2. The creation of a new habitat for a species.

  3. The pollution of a river with industrial chemicals.

  4. The selective breeding of a plant or animal species.


Correct Option: C
Explanation:

Pollution can introduce harmful chemicals into the environment that can harm or kill organisms, leading to a decrease in genetic diversity.

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

  1. Increased vulnerability to disease.

  2. Reduced ability to adapt to environmental change.

  3. Increased likelihood of extinction.

  4. Increased genetic diversity.


Correct Option: D
Explanation:

The loss of genetic diversity typically leads to a decrease in genetic diversity, not an increase.

Which of the following is NOT a strategy for mitigating the negative effects of industrialization on genetic diversity?

  1. Conserving natural habitats.

  2. Reducing pollution.

  3. Controlling the spread of invasive species.

  4. Introducing new species to an area.


Correct Option: D
Explanation:

Introducing new species to an area can disrupt the natural ecosystem and lead to a loss of genetic diversity, not a mitigation of its negative effects.

Which of the following is an example of how industrialization can promote genetic diversity in a natural population?

  1. The creation of a new habitat for a species.

  2. The introduction of a new species to an area.

  3. The pollution of a river with industrial chemicals.

  4. The selective breeding of a plant or animal species.


Correct Option: A
Explanation:

Creating a new habitat can provide a new environment for a species to thrive in, leading to an increase in genetic diversity.
