How does the

genome of the novel organism likely compare to the human genome? (1 mark)

What is the most

likely classification of the novel organism? (1 mark)

The ecologists

used a quantitative PCR (qPCR) assay to investigate the abundance of the novel

organism in several different ecological niches including hydrothermal vents,

deep-sea sediments and shallow coastal waters. The qPCR assay was performed

using a primer that specifically targeted a gene

carried by the novel organism.

Examine the

qPCR results shown above. Which ecological niche (hydrothermal vents, deep-sea

sediments, shallow coastal waters) had the highest abundance of the novel

organism? Briefly explain how you reached this conclusion. (2-3 sentences) (2
