Answer:
Liquid volume is usually measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass or plastic tube sealed at one end, with a calibrated scale etched (or marked) on the outside wall.

Answer:
a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system
Explanation:
- Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
- In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
- The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
- The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
Answer:
The correct answer is option C. One system is switched on while the others are switched off is a false statement.
Explanation:
A biological energy system is a set of biochemical reactions known as metabolic processes that are concerned with the energy flow in an organism. In these processes energy converts into the ATP that is helpful in all types of cellular or muscular activity.
In the biological energy system, multiple or more than one system can be active at a time its not necessary that one system has to switch off while other is on.
Thus, the correct answer is option C. One system is switched on while the others are switched off is a false statement.
Molecular compound; Molecule
CO2 is an example of a molecular compound or molecule.
A molecule is the smallest particle of a specific element or compound that retains the chemical properties of that element. Molecules are composed of two or more atoms that are joined together by chemical bonds. Molecules may be simple or complex. Carbon dioxide (CO2) is a molecule that contains one carbon atom bonded to two oxygen atoms.
