The answer is B. Primase produces RNA, making it a type of RNA polymerase. RNA is complimentary to a single strand of DNA.
Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together. Scientists can measure the amount of energy stored in foods using a device called a bomb calorimeter. With this technique, food is placed inside the calorimeter and heated until it burns. The excess heat released by the reaction is directly proportional to the amount of energy contained in the food.
The tissues that are described as voluntary and involuntary would be MUSCULAR TISSUES or MUSCLES; with voluntary muscles having controlled by one's own will while involuntary muscles work without conscious control.
