Answer:
Using microscopy methods such as fluorescence microscopy and polymerase chain reaction (PCR).
Explanation:
A bacterium that is viable but non-culturable refers to those bacteria that are in a very low metabolic state (dormant state) that don’t grow but is alive. Methods based on culture will not be able to detect a viable but non-culturable bacteria, because these bacteria will not grow and in few cases if the bacterium could be cultured, it only grows in very specific conditions. The most common methods used to check for the presence of bacteria that are viable but non-culturable is the fluorescence microscopy. The disadvantage of this technology is that don’t discriminate between live and dead cells, it only detects its presence. Another common technology is a polymerase chain reaction (PCR), that detects DNA, but this technique also doesn’t discriminate between living or dead cells. But usually is combined with stains to detect a damaged of the membrane, this damage refers to nonviable bacteria.

Why do you think this is happening? (Things
to think about: habitat destruction, erosion,
pollution, invasive species, human impact.)
Answers
Answer:
Well the most common is habittat destruction. With the number of humans only growing, more land is needed and habitat desturctions occur. Lack of food is also a problem, as some crops don’t grow as much so the bee’s food source is smaller which leaves thousands dead. Also if the food source doesn’t run out, there are pesticides sprayed and the bees will die if eaten one which the chemical properties in a pesticide will kill. Also if not used, littering, if you dump it into a water source, the water gets contaminated and the bees could die from that, or the water spreads ano the flower would receive this chemical property, which could kill the Bee’s food source, or the flower doesn’t die but when the bees consume it, the bee will die.
