What is genetic diversity?

  1. The variety of different genes and alleles in a population.

  2. The number of different species in an ecosystem.

  3. The number of different habitats in an ecosystem.

  4. The number of different individuals in a population.


Correct Option: A
Explanation:

Genetic diversity is the variety of different genes and alleles in a population. It is important for the survival of a species because it allows for adaptation to changing environmental conditions.

What is thermal pollution?

  1. The release of heat into a natural body of water.

  2. The release of chemicals into a natural body of water.

  3. The release of sewage into a natural body of water.

  4. The release of oil into a natural body of water.


Correct Option: A
Explanation:

Thermal pollution is the release of heat into a natural body of water. It can be caused by power plants, factories, and other industrial activities.

What are the effects of thermal pollution on aquatic ecosystems?

  1. Increased water temperature.

  2. Decreased dissolved oxygen levels.

  3. Increased growth of algae and other aquatic plants.

  4. All of the above.


Correct Option: D
Explanation:

Thermal pollution can have a number of negative effects on aquatic ecosystems, including increased water temperature, decreased dissolved oxygen levels, and increased growth of algae and other aquatic plants.

How does thermal pollution affect genetic diversity?

  1. It can cause mutations in genes.

  2. It can lead to the loss of genetic diversity.

  3. It can increase genetic diversity.

  4. None of the above.


Correct Option: B
Explanation:

Thermal pollution can lead to the loss of genetic diversity by causing mutations in genes and by selecting for certain genotypes that are more tolerant of high temperatures.

What are some ways to reduce thermal pollution?

  1. Using cooling towers.

  2. Using heat exchangers.

  3. Planting trees around bodies of water.

  4. All of the above.


Correct Option: D
Explanation:

There are a number of ways to reduce thermal pollution, including using cooling towers, using heat exchangers, and planting trees around bodies of water.

Why is genetic diversity important for the survival of a species?

  1. It allows for adaptation to changing environmental conditions.

  2. It increases the chances of finding a mate.

  3. It helps to prevent disease.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity is important for the survival of a species because it allows for adaptation to changing environmental conditions, increases the chances of finding a mate, and helps to prevent disease.

What are some examples of genetic diversity in action?

  1. The ability of some plants to tolerate drought.

  2. The ability of some animals to migrate to warmer climates in the winter.

  3. The ability of some bacteria to resist antibiotics.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity is in action when some plants can tolerate drought, some animals can migrate to warmer climates in the winter, and some bacteria can resist antibiotics.

What are some threats to genetic diversity?

  1. Habitat loss.

  2. Pollution.

  3. Climate change.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity is threatened by habitat loss, pollution, and climate change.

What can be done to protect genetic diversity?

  1. Protecting habitats.

  2. Reducing pollution.

  3. Mitigating climate change.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity can be protected by protecting habitats, reducing pollution, and mitigating climate change.

What is the relationship between genetic diversity and thermal pollution?

  1. Thermal pollution can cause mutations in genes.

  2. Thermal pollution can lead to the loss of genetic diversity.

  3. Thermal pollution can increase genetic diversity.

  4. None of the above.


Correct Option: B
Explanation:

Thermal pollution can lead to the loss of genetic diversity by causing mutations in genes and by selecting for certain genotypes that are more tolerant of high temperatures.

What are some examples of how thermal pollution can affect genetic diversity?

  1. Thermal pollution can cause mutations in genes that lead to the loss of important traits.

  2. Thermal pollution can select for certain genotypes that are more tolerant of high temperatures, leading to a decrease in genetic diversity.

  3. Thermal pollution can cause changes in gene expression that can lead to the loss of important traits.

  4. All of the above.


Correct Option: D
Explanation:

Thermal pollution can affect genetic diversity by causing mutations in genes that lead to the loss of important traits, selecting for certain genotypes that are more tolerant of high temperatures, leading to a decrease in genetic diversity, and causing changes in gene expression that can lead to the loss of important traits.

What are some ways to mitigate the effects of thermal pollution on genetic diversity?

  1. Reducing the amount of heat released into water bodies.

  2. Using cooling towers to reduce the temperature of water before it is released.

  3. Planting trees around water bodies to provide shade and reduce the amount of heat absorbed by the water.

  4. All of the above.


Correct Option: D
Explanation:

The effects of thermal pollution on genetic diversity can be mitigated by reducing the amount of heat released into water bodies, using cooling towers to reduce the temperature of water before it is released, and planting trees around water bodies to provide shade and reduce the amount of heat absorbed by the water.

Why is it important to protect genetic diversity in aquatic ecosystems?

  1. Genetic diversity allows aquatic organisms to adapt to changing environmental conditions.

  2. Genetic diversity helps to ensure that aquatic ecosystems are resilient to disturbances.

  3. Genetic diversity provides a source of new traits that can be beneficial to aquatic organisms.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity is important in aquatic ecosystems because it allows aquatic organisms to adapt to changing environmental conditions, helps to ensure that aquatic ecosystems are resilient to disturbances, and provides a source of new traits that can be beneficial to aquatic organisms.

What are some specific examples of how genetic diversity has helped aquatic organisms to adapt to changing environmental conditions?

  1. Some fish species have evolved the ability to tolerate higher water temperatures.

  2. Some coral species have evolved the ability to tolerate more acidic water.

  3. Some aquatic plants have evolved the ability to tolerate higher levels of pollution.

  4. All of the above.


Correct Option: D
Explanation:

Genetic diversity has helped aquatic organisms to adapt to changing environmental conditions in a number of ways, including evolving the ability to tolerate higher water temperatures, more acidic water, and higher levels of pollution.
