Answer:
i think its C sorry if I am wrong
<u>Answer</u>:
1. The purpose of the uninoculated control tubes used in the oxidation fermentation test is to serve as basis of the medium for the color comparison and that it is sterile.
2. It is necessary to use two controls in order to illustrate the no color change (green color) under both aerobic and anaerobic conditions.
3. The purpose of the experiment is to determine if the organisms utilize the carbohydrate and thus is fermentative. This will result in a color change from green to yellow.
Thus, the medium in one tube is sealed with a layer of paraffin to prevent diffusion of oxygen. This tube will show that the medium is unaffected by the lack of oxygen.
The second tube will allow the diffusion of oxygen. This tube will show that the medium does not change color naturally in the presence of oxygen. Thus, the color changes will be caused only by the fermentation process of the organisms.
Answer:
The correct answer is - false statement.
Explanation:
The statement mentioned in question explaining the process of metabolism. Metabolism is a procedure that includes catabolic and anabolic process that which are chemicals reactions takes place in the body. Metabolism is breaking large molecules into simpler and simpler molecules to synthesizing complex molecules from simpler molecules.
Digestion is the process in which ingested food break down to simpler substances and absorbed to provide nutrients to body.
Thus, the correct answer is - false statement.
