Answer 1

Answer:

photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer 2

Answer:

Correct option is

B

x=3;y=2

Given equations are

2x+3y=12 ....(1)

and 5x−3y=9 ....(2)

Add both the equations to eliminate y, we get

7x=21

⇒x=3

Substitute this value in equation (1),

2(3)+3y=12

⇒6+3y=12

⇒3y=6

⇒y=2

Therefore, the solution is x=3,y=2.
