photosynthesis: C6H12O6 = 6 O2 + 6 CO2 + 6 H2O
breathing: C6H12O6 + 6 O2 6 CO2 6 H2O ATP
Cellular respiration and photosynthesis are complement reactions to each other. These are reverse reactions. In cellular respiration glucose (C₆H₁₂O₆) and oxygen (O₂) yield carbon dioxide (CO₂) and water (H₂O) and energy is released in the form of ATP. In the opposite reaction - in photosynthesis, carbon dioxide (CO₂) and water (H₂O) yield glucose (C₆H₁₂O₆) and oxygen (O₂).

B. DDT decomposes.
C. DDT was genetically engineered.
D. DDT bioaccumulates.
Answer: D. DDT bioaccumulates
Bioaccumulation is the accumulation of substances or compounds such as pesticides, fertilizers or other chemicals in the body of the organisms. These substances or compounds are toxic and remain undigested in the body of the organisms are transferred subsequently in a food chain, when one organism is consumed by another organism. The highest trophic level is most effected because of the concentration of the toxic substance is the maximum.
DDT (dichlorodiphenyltrichloroethane) is a colorless, odorless and tasteless crystalline chemical compound. It is used as a pesticide to kill pests in agricultural field. DDT is highly toxic chemical compound. It remains undigested in the body of the organism and transferred in a food chain when one organism is consumed by another organism. The effect of DDT is magnified several times in the top most trophic level in the food chain due to bioaccumulation.

Answer:
false
Explanation:
Answer:
The correct answer would be plasma membrane or cell membrane.
Plasma membrane is phospholipid bilayer structure which separates the intra-cellular components from extra-cellular environment.
One of the most important characteristics of the plasma membrane is that it is selectively permeable in nature.
It allows some substances to move freely in and out of the cell while restricts the movement of other substances. It is similar to function of security guard who decides whom may enter and whom may not.
Small molecules and uncharged particles can travel across the plasma membrane easily by simple diffusion. For example, exchange or diffusion of gases (carbon dioxide and oxygen) across the cell. The movement of such substance depends upon its concentration gradient across the membrane.
Charged particles and large sized substances require protein channels to travel across the cell. Such substances are transported either with the help of facilitated diffusion or active transport.
