Warm Up 2/21 Use the following diagrams to define gene flow and founder effect. Founder effect Gene flow Two species of sunflowers grow on either side of a mountain. For a while, the two sunflower populations evolve separately. With the climatic changes an animal population crosses from one side of the mountain chain to the other, bringing some sunflower pollen with it. This movement is called-?

Warm Up 2/22 or 2/23 1. What are pathogens? 2. List 3 properties of living cells. 3. Are viruses considered living? Why or why not? 4. What would happen if a global outbreak of a virus occurred? 5. List at least 3 sicknesses caused by viruses. http://www.cbsnews.com/news/zika-virus-aedes-mosquito-birth-defects- centers-for-disease-control-and-prevention-travel-alert/

Warm Up 2/24 How are viruses transmitted? How does the lysogenic cycle compare to the lytic cycle? What can be done to prevent sickness from a virus? What is unique about the HIV virus? What material do viruses and living cells have in common?
