What is 12% of 89?
Percentages are just fancy multiplications where you move the decimal over 2 spots to the left at the end. 12 x 89 = 1068 Move the decimal two to the left to get 10.68 (the answer) Why this works: The % sign is "per cent" where "per" means divide and "cent" means 100 (you see this with the penny - it is one cent out of the 100 which make up a dollar). You *divide* the multiplication answer by *100* to get the "percent" value. Fun fact: Percentages are actually reversible, so 12% of 89 is equal to 89% of 12. This is because 12 x 89 is equal to 89 x 12.

Biological Diversity: How do you know that a border collie and a golden retriever are both dogs? Is a wolf a dog? What about a hyena? What are the determining characteristics and why is this important to understand?
Scientists began using simple things like morphology (appearances) to categorize living things. This helps us better understand how the world works, making it more predictable and allowing humans to make informed choices. We've had to tweak our understanding numerous times over the decades but it has always lead to an improved understanding of how the world works.
