Caused by which organism?

What evidence could the sputum give for this case?

Is the increased respiration rate and unequal chest movement indicative of the pathology?

Is this a bacterial or viral disease?

Answer:

Alzheimer disease may be defined as a type of the progressive disorder that mainly destroys the memorizing capacity of the individual. The disease gets worsen with the age.

After studying the case disease given in the question it can be inferred that the individual might have pneumonia caused by the bacteria  Klebsiella. This causes the damage to the lungs. The sputum shows that the bacteria is gram negative that are covered with the rods. If the bacteria is grown on the agar plate of the MacConkey, the bacteria becomes mucoid due to the production of the slime. This might cause the lung damage and causes inflammation that causes the observable changes. This is a bacterial disease.

1. Analyze Graphs What trend in the monarch population does the graph show?
Vlada [557]

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.
