Question

what did you learn from that experience? now that youve successfully shifted the beak size of the finches of daphne major, answer the questions below. a single finch, over the course of its life, can change the size of its beak based on the food source available. a group of finches can, over time, have a different percentage of individuals with small and large beak sizes based on the food available. only some birds in a population can change their beak size. when rainfall decreases, large seeds are the main food source on daphne major. when small seeds are common, birds with larger beaks have an advantage.

Explanation:

1. A single finch cannot change its beak size during its lifetime as beak - size is a trait determined by genetics, not by short - term environmental changes during an individual's life. So the first statement is false.
2. A group of finches can experience changes in the proportion of individuals with different beak sizes over time due to natural selection based on food availability. This is true.
3. All birds in a population with genetic variation for beak - size can potentially be affected by natural selection, not just some. So this statement is false.
4. When rainfall decreases, plants produce larger and harder seeds, and large seeds become the main food source on Daphne Major. This is true.
5. When small seeds are common, birds with smaller beaks have an advantage as they can more easily handle and eat the small seeds. So this statement is false.

Answer:

1. false
2. true
3. false
4. true
5. false
