Question is incomplete. Complete question is as follows:

A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of 1.The mutation will lead to 2..

1.

A.Embryology

B. Evolution Genetics

C.Comparative Anatomy

2.

A. All the bacteria becoming resistant to the specific Antibiotics

B. The Bacteria becoming nonresistant to specific Antibiotics

C. Less Bacteria becoming resistant to the specific Antibiotics

1. B. Evolution Genetics

2.C. Less Bacteria becoming resistant to the specific Antibiotics

Explanation:

Evolution genetics is the field in which evolutionary changes in genome are studied. Here, the bacterial population was exposed to the antibiotic. In response, some bacteria showed mutations in their genome which made them resistant to the antibiotic. Since the genetic composition of bacteria has changed and made them to evolve, it would be a part of evolution genetics.

The fewer bacteria which showed these mutations became resistant to that particular antibiotic. However, this does not mean that the entire population will become resistant to the antibiotic. It is going to take a long time.

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.
