Several groups of researchers were conducting experiments to study how exercise affects cholesterol levels. One group had colleg

e students run two miles a day for six weeks. Another group had senior citizens participate in gentle water aerobics twice a week for a year. Cholesterol levels dropped slightly among the college students but dropped significantly among the senior citizens. Based on these results, what should the researchers plan to do next to validate the findings?

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.

What distance would be covered in 10
Brrunno [24]

Answer:

The correct answer would be - 5000 meter or 5 kilometers

Explanation:

Given:

Speed = 500 meter/minute

Time = 10 minutes

Distance would be covered = ?

Formula used:

speed = distance/ time

then, Distance = speed*time

Solution:

Putting values in the provided formula:

Distance = speed*time

distance = 500*10 meters

              = 5000 meters or 5 kilometer (1000 meter = 1 kilometer)

dezoksy [38]

Answer:

<em>The shape of a cell can easily be seen through a light microscope.</em>

Explanation:

A microscope can be defined as a device which is used to visualize things which are otherwise not visible to the naked eye. The shape of a cell can be seen even through a light microscope. For example, an animal cell can be seen to have a round shape under the light microscope, a plant cell will be seen rectangular under the light microscope.

Other microscopes such as the electron microscope can even show the organelles present inside the cell.
