Answer:
Photosynthesis is the action of how plants break down blue light rays and then reconstructs it into energy
Step-by-step explanation:
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.
There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.

Answer:
x + 3y = 21
Step-by-step explanation:
Equation of the line: y =mx+ b
Multiply the equation by 3
3y = -x + 21
x + 3y = 21
Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
