Which statement BEST explains which model accurately shows how natural selection works? A.
Student B’s model shows a variation in the initial population of bacteria which led
to some bacteria surviving the antibiotic and reproducing while the other bacteria
died off.

died off.

C.
Student B’s model shows how some bacteria changed themselves in the initial
population of bacteria which led to those bacteria surviving the antibiotic while
the other bacteria died off.

D.
Student A’s model shows how some bacteria changed themselves in the initial

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.

Long term exposure to waves can cause sunburns and skin cancer.

Jason adds the antibiotic penicillin to a bacterial culture. the bacteria develop genetic modifications in their genome, which gives them resistance to the antibiotic penicillin. what caused this genetic modification?
