The first one is the light bends sheikh is known as refraction
Answer:
D
Explanation:
Gene flow is the transfer of genetic variation from one population to another
W work
F force
s distance
If F = constant:
W₁ = F·s
If you triple the force and the distance:
W₂ = 3F · 3s = 9 F·s = 9 W₁
We use only one variable at a time to find the accurate result. We want to see how the result of experiment changes everytime with a single variable.
