Biography

I'm a trans woman who has fallen on hard times due to COVID. Until March I had a solid job as a substitute teacher in the Mukilteo School District in Everett, WA, but the virus took that. I was also a student teacher there, working toward a full teaching license. My initial background is in Biology, which I am also extremely happy to do lessons on. I took the pre-med track in college, and was set to go to med school until I realized that my anxiety would make me the worst doctor ever. Teaching is absolutely my speed!

Biology: The Essentials

Seconds after thoroughly washing your hands, you grab a doorknob with your right hand. One million bacteria are transferred from the doorknob to your hand. You immediately put on latex gloves for a lab dissection; the gloves provide a warm, moist environment that is ideal for bacterial growth. If the bacteria divide once every 40 minutes, approximately how many bacteria will be on your right hand in 2 hours?
