Can you please help me with these two questions? I will give you branleyist if you answer. 1. Discuss the significance of chlorophyll. Explain its role in photosynthesis. Why are plants green?

2. Why are plants essential to life on Earth? Explain the role photosynthesis plays in this. Why do animals need plants?

1. Chlorophyll is the pigment in plats that absorbs light. If plants were not able to absorb light they would not be able to do photosynthesis and they would not be able to survive. Plants are green because green light is the only wavelength not absorbed by the chlorophyll in plants so this is the color o light that gets reflected back to our eyes.

2.Plants are essential to life on Earth because they convert energy from the sun into stored energy which can be used by animals. They are also essential because one of the outputs of photosynthesis is oxygen which is necessary for breathing and sustaining life. Animals need plants because plants produce oxygen and because animals are unable to convert solar energy into usable energy themselves so they need plants to convert solar energy into chemical energy, which is done through the process of photosynthesis. Animals need this so that animals can use the stored energy that is produced by the plants.

answer: huh

step-by-step explanation:

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
