What distinguishes adaptations from acclimatization?
What distinguishes adaptations from acclimatization?
- Adaptations involve genetic changes, while acclimatization involves environmental changes.
- Adaptations occur over long periods, while acclimatization happens in response to short-term changes. (correct)
- Adaptations focus on phenotypic changes, while acclimatization focuses on genotypic changes.
- Adaptations increase fitness, while acclimatization decreases fitness.
What is the impact of adaptations on the population fitness?
What is the impact of adaptations on the population fitness?
- Decrease fitness of a population
- Increase reproductive rate but not fitness of a population
- Increase fitness of a population (correct)
- Have no impact on the fitness of a population
Which statement best describes the concept of 'trade-offs' in adaptations?
Which statement best describes the concept of 'trade-offs' in adaptations?
- Trade-offs are compromises that do not affect the fitness of a population.
- Trade-offs are inescapable compromises between traits that cannot be optimized simultaneously. (correct)
- Trade-offs involve optimizing all traits simultaneously.
- Trade-offs are traits that always work together perfectly.
