Answer:
Let's analyze the graph.
we can see that in 1995, the total area occupied was around 8 he.
Then we have a steep increase, reaching a maximum in the year 1997, where the area occupied was 20 he.
After that the area decreases abruptly and remains (varying a little from year to year) around 5he
Now we can look at the year 2006, that year the area was around 5he, ut after that we can see an almost constant decrease in the area, where each year (except from 2010 to 2011) the area decreased.
Ending in 2014 near 1 or 2 hectares.
The conclusion that we can take from this graph is that, while some years ao the area fluctuated around some values, in recent years we can see a clear decrease in the area ocuppied by the Overwintering Monarchs.

Answer: C. When they mixed, some of the bacteria from strain X obtained plasmids from strain Y, these plasmids gave them DNA that allowed them to resist the antibiotic.
Explanation:
Conjugation is a mode of sexual reproduction used by some strains of bacteria to reproduce. In this the bacteria transfers the genetic material to another bacteria through direct contact. In this one bacteria act as a donor and another one act as a recipient.
The strain X which was affected by the antibiotic might have mixed with the strain Y, as a result of this strain X being not resistant with the antibiotic died. But when this bacterial strain got mixed with the strain Y, which is antibiotic resistant. The strain X might received the antibiotic resistant property from strain Y through sexual reproduction by the mode of conjugation. In this plasmid DNA transfer from strain Y to strain X, helped strain X to develop antibiotic resistance, and further helped strain X to survive.
Viruses are not living things, the are proteins with a genetic code to replicate however. Viruses do not require food to live therefore, they do not need those special structures.
