Answer:
The initial release of sulfur dioxide and nitrogen oxides creates water pollution.
These compounds chemically react to create acid rain which falls back to Earth, polluting both Water and Ground. It can even cycle back to the atmosphere through evaporation.
Chewing bread, tearing paper, breaking rocks
The answer is A. They produce food by photosynthesis.
The function of leaves is taken on by stems of such cacti.
The total mass of A and C which are glucose and oxygen, is equal to the total mass of B and D, which are water and Carbon dioxide.
the law of conservation states that no energy or matter should be lost during a reaction therefore total masses should be equal so you're looking to 2 numbers that equal each other when added and the only 2 are A and C equal B and D
In respiration we know that the waste products are water vapor (H2O) and carbon dioxide.
Which makes the last statement correct.
