true
false
question 7

true
false
question 8
the equation for respiration has c₆h₁₂o₆ as a reactant and h₂o as a product
true
false
question 9
the earths atmosphere is actually quite thin and the bulk of it is within the first 50 miles from earth.
true
false
question 10
organic compounds all contain what element and is the backbone of all life on earth
oxygen

Explanation:

• Question 6: Climate change is a complex issue. Recycling and using energy - efficient bulbs help but cannot stop it alone.
• Question 7: The photosynthesis equation is $6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2$, so water is a reactant and sugar ($C_6H_{12}O_6$) is a product.

• Question 8: The respiration equation is $C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O$, so $C_6H_{12}O_6$ is a reactant and $H_2O$ is a product.

• Question 9: The Earth's atmosphere is thin relative to the size of the Earth, and most of its mass is within the first 50 miles.
• Question 10: Organic compounds contain carbon, not oxygen. Carbon is the backbone of life.

Answer:

• Question 6: B. False
• Question 7: A. True
• Question 8: A. True
• Question 9: A. True
• Question 10: None of the provided options are correct (should be Carbon).
