Create an experiment where you would use both a Southern blot and a Northern blot to determine if a newly isolated bacterium con
natta225 [31]

Answer:

■Gene sequences would be used to make Probes for both the Southern and Northern blots.

■The probes will be used to view the presence of each gene with the use of isolated genomic DNA obtained from the isolated bacterium

■Each probes hybridized to the genome shows the pathway is isolated and point of the genes were involved in the substrate catabolism

■The carbon source in the isolate is derived from the substrate inducing the catabolic pathway as RNA determine transcripts present

■Probes hybridizing to the same sequences would be used to determine the gene activity for the pathway as seen in the southern one

■since all the genes present in the genome couldn't be identified, the northern would be important to work on

■Catabolic pathway is determined by the same genes. Hence, the need for gene/transcript probes to hybridize to the transcriptome.

9. You find a rock 7,500 km away from the nearest seafloor spreading center. The plate is spreading at 5 cm/year, how old is the
Anna [14]
The answer is 150,000,000 years (150 million years)

Let's first convert 7,500 km to cm:
1 km = 100,000 cm
7,500 km = 7,500 · 1 km = 7,500 · 100,000 cm = 750,000,000 cm

Now, it is known that the plate is spreading at 5 cm per 1 year. Make a proportion:
5 cm : 1 year = 750,000,000 cm : x
x = 750,000,000 cm · 1 year ÷ 5 cm = 150,000,000 years

The snail in layer E of image 1 is a previously unidentified species. How can scientists determine the relative age of the fossi
shepuryov [24]

The scientists will use Relative dating. It is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
