<span>Chromated copper arsenate, or CCA, is a pesticide that has been used for years in
pressure-treating lumber to prevent destruction from rot and insects. Arsenic, a toxic
chemical, can leach from this treated wood, leaving residues on the wood’s surface and in
nearby soil. Young children who play on or near decks or playscapes made from CCA-
treated wood can get arsenic on their skin and into their bodies, especially if they eat or
drink without washing their hands.
Because of the health risks of long-term exposure to arsenic, the Environmental
Protection Agency (EPA) has announced that as of December 31, 2003, arsenic Currently the EPA does not recommend that people remove existing structures made with CCA-treated wood or the soil surrounding those structures.

Answer:
Option A
Explanation:
Prokaryotic cells do not have specialized tasks because they are mostly unicellular (in rare cases multicellular) and don't have a nucleus.
C=1* 12.01g=12.01g
0=2*16.00g=32.00g
co2=44.01g
(12.01g/44.01g)* 100%=27.289%
0.27*88g=23.76g
or more accurately
0.2289*88g=24.01g
there is about 24 grams of carbon dioxide
