Aresearcher wants to know if gene flow is contributing to evolution of drought tolerance of pitcher plants in a specific bog. as a control, she should a. determine if the population is in hardy-weinberg equilibrium b. transplant pitcher plants from other populations into the bog. oc. estimate the frequency of alleles at relevant genes for drought tolerance. d. all of the above steps should be taken. e. none of these steps should be taken; gene flow does not contribute to evolution.

the correct option is option a

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

1. is geographic distribution

2 is increasing complexity

3 is transitional forms

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
