Thermal conductivity measures the ability of a material to
(A) store heat
(B) transfer heat
(C) store electricity
(D) transfer electricity
The answer is: (B) transfer heat

Which gas do plants absorb from the atmosphere for photosynthesis?
(A) Oxygen
(B) Nitrogen
(C) Carbon monoxide
(D) Carbon dioxide
The answer is: (D) Carbon dioxide
Plants primarily absorb carbon dioxide (CO2) from the atmosphere for photosynthesis. The photosynthesis is the process that plants use to convert light energy into chemical energy, which is stored in glucose (sugar). This process is essential for most life on Earth as it produces the oxygen we breathe.
