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.

A seismometer is used to measure the motion in the ground caused by earthquakes, volcanoes, or explosives.
Answer:
The correct answer is option B. "Fill a clear cube with them".
Explanation:
Sugar crystals, colloquially known as "rock candy", are conglomerates of sugar molecules that are formed when sugar-saturated water are cooled. Sugar crystals are arranged in a three dimensional repeating pattern, forming a cube like structure. Therefore, Juan could fill a clear cube with its plastic foam balls to represent sugar crystals. I attached an image of sugar crystals dissolving in water as reference.
Explanation:
Cold springs can affect the reproduction of rabbits as the rabbit's main priority is to survive before adding more to its family as they would already be struggling to keep itself warm. Yet alone a newborn rabbit which doesn't have any fur yet.
Also, cold springs could affect the amount of food that grows so the competition for food is more harsh so more rabbits are likely to die of starvation.
Though I'm not sure what your temperature range of a cold spring is so I might be giving extreme answers.
