Scenario C: Your Uncle raises beef cattle and is considering adding low amounts of antibiotics to their feed because he heard it makes them grow larger. Explain to him: The concept of using antibiotics for "essential use only." The process of natural selection. How low levels of antibiotics select for resistant bacteria. How these antibiotic resistant bacteria can then be harmful to not only cows, but also humans.

What technology revolutionized and enabled the human genome project? What are some of the ways that it revolutionized our view of genetics and our ability to study the microbiome?

You are a public health official responding to a recent outbreak of cholera in Yemen. What step(s) would you recommend to local officials that would cause the bacteria to evolve to be less virulent, and therefore less deadly? Explain your answer.

In 200-300 words, DISCUSS the importance of BIOREMEDIATION

The diagram shows one possible evolutionary history based on genetic sequences from Schmidt's patients, Nurse Trahan and local controls. According to this diagram below, what conclusion would you draw? (a) (b) Schmidt's patient *** Trahan Local controls Local control Schmidt's patient Local control Local control Trahan Local control Local control

Are gene mutations caused by selective pressures in the environment? In other words, do gene mutations arise in an organism out of need or want? Group of answer choices A. No, because gene mutations are not purely random. B. Yes, because gene mutations are not purely random. C. No, because gene mutations are purely random. D. Yes, because gene mutations are purely random.

Transformation is a form of horizontal gene transfer that involves random mutation. physical contact between cells. viral infection. acquisition of DNA from the environment.

Human Skin Color: Evidence for Selection Name: Jayden Bodisto Make observations of the Figure below. Then complete the portion below. Erythemal UV index 80 0 09- KNMI/ESA -120 0 -120 2 4 -60 6 8 10 60 Clear-sky 24 September 2015 120 10 60 12 14 120 16 -60 18 Figure 1. Ultraviolet Radiation Index Across the World. The colors on this map of the world represent Ultraviolet (UV) Index values on a particular day in September 2015. The UV Index is a standardized scale of UV radiation intensity running from 0 (least intense) to 18 (most intense). The y-axis values are degrees of latitude, which range from the equator (0°) to the poles (90° north and -90° south). The x-axis values are degrees of longitude, which range from the prime meridian (0°) to the antimeridian (180° east and -180° west).
