Life Science : Bacteria can divide in every 20 minutes. So 1 bacterium can multiply to 2 in 20 minutes. 4 in 40 minutes, and so on. How many bacteria will there be in 6 hours? Write your answer using exponents, and then evaluate. Most bacteria reproduce by a type of simple cell division known as binary fission. Each species reproduce best at a specific temperature and moisture level. 15-04-2018 Writing Strategy Write a Convincing Argument Your ability to write a convincing argument proves that you have understanding of the concept. An effective argument should include the following four parts: Compare 102 and 210. For any two numbers, which usually 1. A goal gives the greater number, 2. A response to the goal using the greater number as 3. Evidence to support the response the base or as the exponent? Give atleast one exception. 4. A summary statement Step 1 : Identify the goal For any two numbers, explain whether using the greater number as the base or as the exponent will generally result in a greater number. Find one exception. Step 2 : Provide a response to the goal Using the greater number as the exponent usually gives the greater number. Step 3 : Provide evidence to support your response For the number 10 and 2. Exception for the numbers Using the greater number, 2 and 3, using the greater 10, as the exponent will number, 3, as the exponent result in a greater number. will not result in a greater 102 = 100 number. 210 = 1024 32 = 9 100 < 1024 23 = 8 102 < 210 9>8 32 > 23 Step 4 : Summarise your argument Generally, for any two numbers, using the greater number as the exponent instead of as the base will result in a greater number. 15-04-2018
