Evolution and Biotechnology Quiz

How does the environment influence the survival of certain traits in a population?

• It has no influence on traits

• It selects for traits that are advantageous

• It eliminates all genetic variation

• It only impacts traits in laboratory settings

What is the name of the process where people breed plants or animals for specific characteristics?

• Natural Selection

• Artificial Selection

• Genetic Drift

What molecule carries the hereditary information in animals?

• Lipid

• Carbohydrate

• DNA

• Vitamin

Which process involves changing an organism's genetic material directly?

• Natural Selection
• Artificial Selection
• Genetic Engineering
• Mutation

Henry is studying two ways that traits can change in plants. In one method, scientists use technology to directly change the DNA of a plant to get specific results. In the other method, plants with certain traits survive and reproduce over many generations without human intervention. How does genetic engineering differ from natural selection?

• Genetic engineering is random

• Genetic engineering is directed by human intervention

• Natural selection involves no changes

• Only genetic engineering creates variations

Why is a certain characteristic considered advantageous in the process of natural selection?

• It is the brightest trait

• It helps an organism reproduce successfully.

• It is the fastest trait

• It is the oldest trait

Which of the following best describes artificial selection compared to natural selection?

• Artificial selection happens without human intervention

• Artificial selection is driven by human preferences, while natural selection is driven by nature

• Natural selection produces more rapid changes than artificial selection

• Artificial selection does not result in new traits

How do genetic variations contribute to the process of natural selection?

• Variations have no impact on survival
• Variations create identical organisms
• Variations provide different advantages in specific environments
• Variations always prevent reproduction

What is the term for a trait that is inherited from one generation to the next?

• Mutation

• Adaptation

• Heritable

• Variation

In natural selection, what does 'survival of the fittest' primarily mean?

• The strongest organism always wins
• Organisms best adapted to their environment are more likely to survive and reproduce
• Only the largest organisms survive
• Organisms with the most offspring always survive
