They are mostly found in humans
Answer:
<em>A. 38%</em>
Explanation:
Percentage increase = (Increase/original value)×100
P.I.C= (ΔC/C₁)×100 .................. Equation 1
Where P.I.C = Percentage increase in the concentration of carbon dioxide from 1790 to 2007, ΔC = increase in the concentration of carbon dioxide from 1790 to 2007,
C₁ = concentration of carbon dioxide in 1790.
But,
ΔC = C₂ - C₁............................. Equation 2
Substituting equation 2 into equation 1.
P.I.C = [(C₂ - C₁)/C₁]×100.................... Equation 2
<em>Given: C₁ = 278 ppm, C₂ = 383 ppm</em>
<em>Substituting into equation 2</em>
<em>P.I.C = [(383-278)/278]×100</em>
<em>P.I.C = (105/278)×100</em>
<em>P.I.C = 37.77%</em>
<em>P.I.C ≈ 38%</em>
<em>The right option is A. 38%</em>

Answer:
Different beaks are adapted for differnt food soruces, because if a bird or animal needs a beak to scoop up animals it will be shaped differently than a bird/ animal who needs to insert said beak into the ground.
Explanation:
Shaping. Each step in the learning process is called an approximation. An animal may be reinforced for each successive approximation toward the final goal of the desired trained behavior. Animals learn complex behaviors through shaping.
