Answer:
1. Archipelago in Ecuador
2. Different beaks
3. He used Darwinism/ survival of the fittest / evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. mutation, gene flow, genetic drift, and natural selection.
Mutation creates new genetic variation in a gene pool.
Gene flow and genetic drift alter allele frequencies in a gene pool.
5. The finches have few predators / competition for food.
Explanation:
A pH environment has a significant effect on an enzymes. It can affect the intramolecular forces and change the enzyme's shape -- potentially to the point where it is rendered ineffective. With these effects in mind, typical enzymes have a pH range in which they perform optimally. For example, alpha amylase, which found in the mouth, operates most effectively near a neutral pH. However, lipases operate better at more basic pH levels.
Answer:
Explanation: Natural selection is a cause of evolution. So over time, organisms can start to evolve due to artificial selection. Natural selection, sometimes referred to as "survival of the fittest," is a mechanism for the evolution of a population to become better adapted for survival in a specific environment. This means that organisms with traits that are best suited for the environment will pass these traits to their offspring.
