<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.
Inputs of Cellular respiration are <span>Oxygen (6O</span>₂)<span> and Glucose (C</span>₆<span>H</span>₁₂<span>O</span>₆)<span>
Outputs of Cellular respiration are </span><span>Carbon Dioxide, water, ATP or energy
The main purpose of cellular respiration is to produce ATP. It takes place in the mitochondria.
ATP is the energy of the cells so that it can properly functions inside the body.

The best option for showing locations of housing and industry on a city map is drawing a circle around the industrial areas. Thus option "C" is correct.
<h3>What are general reference maps?</h3>
Road maps and historical maps are general reference maps as it shows the physical (natural and man-made) features in an area and can use different colours to differentiate different rods and locations.
Early formed maps or historical maps are general reference maps as it can represent the discovery of a landscape briefly.
Thus option "C" is correct.

Answer:
Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases, so it would affect the water negatively.
