The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. ... The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body.
The respiratory system does not work alone in transporting oxygen through the body. The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.
Explanation:
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.
<h3><em><u>C.</u></em><em><u> </u></em><em><u>This cell has no nucleus.</u></em></h3>
Because bacterial cell do not have a well-defined nuclear membrane. The coiled DNA particles lie naked in the cytoplasm. This is called nucleoid. While in animal cells the nucleus is surrounded by a well-defined nuclear membrane.
