Answer;
D. polynucleotide
Explanation;
DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus.
Although each organism's DNA is unique, all DNA is composed of the same nitrogen-based molecules. It is simply the order in which these smaller molecules are arranged that differs among individuals. In turn, this pattern of arrangement ultimately determines each organism's unique characteristics.
At the most basic level, all DNA is composed of a series of smaller molecules called nucleotides.
The deer eat grass. Its droppings, which eventually decompose into the ground, provide minerals and vitamins to the plant roots. This food is vital for it so the plant remains alive and can produce oxygen which is essential for the deer and grass is also a food source for him too.
In terms of the net reactants and products, yes, cellular respiration is the reverse of photosynthesis.
Cellular respiration: Glucose and oxygen are used to make ATP, carbon dioxide, and water.
Photosynthesis: ATP, carbon dioxide, and water are used to make glucose and oxygen.
However, their pathways are NOT the reverse of each other. The enzymes involved are vastly different for each, so only the net reaction is the "reverse."
