It's very hard to see the self-portrait, so I can't identify him.
Thank you for posting your Physics question here. I hope the answer helps. Upon calculating the ramp with the horizontal the answer is 20.49 Deg. Below is the solution:
Y = 7 m.
<span>r = 20 m. </span>
<span>sinA = Y/r = 7/20 = 0.35. </span>
<span>A = 20.49 Deg.</span>
So that we do not contaminate it with microorganisms or garbage or other human stuff.
No they have eukaryotic cells
