Answer:
Put one drop on the dimple tile, and the rest in a test tube. Then put the teat pipette back in the water outside the Visking tubing. Test the drops of liquid in the dimple tile by adding one drop of iodine solution from the dropper bottle. If they turn blue-black, the liquid contains starch.

 All of the factors are responsible for unloading of oxygen from the hemoglobin molecule except the increase in partial pressure of oxygen.
Because the affinity of haemoglobin for binding oxygen increases as  partial pressure of oxygen rises.
<h3>What is  Haemoglobin?</h3>
Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs.
<h3>What are factors that affect Haemoglobin's affinity for oxygen?</h3>
- When used as an oxygen transporter, hemoglobin can carry about 65 times as much oxygen as simple solution in plasma could.
-  A cooperative oxygen-hemoglobin affinity is produced by conformational changes in the molecule.
-  The oxygen-hemoglobin dissociation curve's sigmoidal form reflects this characteristic. 
- Temperature, hydrogen ions, carbon dioxide, and intraerythrocytic 2,3-DPG all have an impact on hemoglobin's affinity, and they all interact with one another.

The question is incomplete as it does not have the options which are:
- there was no sulfur compound added to the medium, that could be used as an electron donor.
- no oxygen was added to the medium so the organism died.
- there is some inhibitory chemical that is preventing the growth of the bacterium.
- you were using the wrong type of sunlight as the energy source for the bacterium.
Answer:
There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
In the given question, the bacteria which are found in the pond uses light energy to use carbon dioxide and form the glucose molecule. These bacteria are known as phototrophic bacteria.
The process of photosynthesis requires an electron donor and an electron acceptor to use molecule.
The organism when provided the light and carbon dioxide artificially in a culture, the bacteria were not able to grow. The reason for this could be accounted as that there was no electron donor found in the media like sulfur which could donate the electron during the chain reaction.
Thus, the selected option is correct.
