Biodiversity is essential to an ecosystem's resistance against viruses and famine. In history, there has been many cases in which a lack of biodiversity has allowed a virus or disease to endemically wipe out an entire species of plant. This will subsequently affect all consumers of each trophic level. Ex: A disease that attacks the DNA of only one certain species of plant would cause decreases in the population of the organisms that rely on eating that plant, the organisms that rely on eating those organisms, and so on. This is caused by a decrease in food source, thus not being able to sustain the ecosystem's demand, thus naturally killing off any organisms that would not be able to find a sufficient food source.
The first one should be correct

Answer:
Fluorescence-Activated Cell Sorting or FACS is a method that allows us to sort out different cell types on the basis of fluorescence emitted by cell membrane components bound compounds.
In the case of CD95 integral protein which is known for highly glycosylated, if use antibodies against cells with CD95 marker, will not identify glycans and can’t be targeted by antibodies as antibodies only recognize protein structures.
Therefore, two different proteins should be used in order to get the correct sorting of cells. One of these would bind to these glycosylations, and the other would be antibodies (with a fluorescent tag) against first.
