When bacteria infect an animal, the number of bacteria in the body increases in an exponential fashion (graph A). After infection by a virulent animal virus with a lytic replicative cycle, there is no evidence of infection for a while. Then the number of viruses rises suddenly and subsequently increases in a series of steps (graph B). Explain the difference in the curves.
Why study Animal Science ★ APSC is an applied science ○ Chemistry ■ Drugs, medicine, taking blood ○ Biology ■ Study of life, organisms ○ Math ■ Dosage of medicine, Feed efficiency, finances Animal Agriculture is a business ★ 100 market steers weigh 1400 lb each @ $125.00/cwt= 125*14 ★ $175,000 on the hoof ○ But have to deduct cost: land, labor, feed, etc ★ Need an understanding of finance, credit, marketing, etc Animal research helps people stay healthy, fed, and clothed ★ U.S. agriculture is the most productive in the world ★ Learning the science behind the biology is critical ★ For every problem solved, another lurks
