Answer:
I am a 10th grader and I've never did anything remotely close to that lol in 6th grade I was doing photosynthesis and oysters. Im actually learning this in my current grade. Covid-19 is actually a cell. All cells have a membrane including Covid-19. Covid-19 has layers of a shield that protects itself and helps it hide from our immune system which makes them so deadly because by the time your immune system realizes its too late the Covid cell went from few hundred to a few million of itself and now your body is in trouble. A cell is similar but replicates itself much slower than Covid. Thats why you get dead skin. Your cells replicates itself and throws away its older cells and replacing them with new ones.
