Mixed Acid Fermentation is a biological process by which a six carbon sugar is converted into complex mixture of acids. It is an example of anaerobic fermentation reaction which is commonly seen in bacteria.
The fermentation produces lactate, acetate, succinate, formate, ethanol, 
and 
and their formation depends upon the presence of certain key enzymes in the bacterium.
The Methyl Red test is used in detecting occurring of mixed acid fermentation pathway when glucose is provided to microbes by using ph indicator. If the fermentation pathway has taken place, the mixture of acids will make the solution very acidic and causes red color change. The Methyl Red test belongs to the group called as IMViC tests.

The answer is D, algae.
—Evidence—
•] Protozoan definition: a single-celled microscopic animal of a group of phyla of the kingdom Protista, such as an amoeba, flagellate, ciliate, or sporozoan.
•] it does not feature algae, therefore it’s D.
Answer: blood calcium level
Explanation:
There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity
, systemic blood pressure, and renal artery/arteriole diameters.
Filtration membrane integrity
: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.
Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.
Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.
Blood calcium level do not have any role in the kidney filterate formation or renal regulation.
Hence, the correct option is blood calcium level.
