An electron microscope would be used for if

Biology
1 answer:
rewona [7]2 years ago
6 0

Answer:

Electron microscope would be used for if,

C) details of cell structures needed to be distinguished.

Explanation:

  • The general principal of electron microscopy is analogous to light microscopy except that it uses electrons to analyse the specimen instead of light.
  • Electron microscopy focuses a beam of electron on the target sample and records the difference in absorption by different surfaces.
  • Electron microscopy is used to get the detailed structure of cells and surface features of various viruses and bacteria.
  • However, it is not possible to view living biological samples through electron microscope because high velocity electron have immense energy to kill living cells.
  • These samples are thus, fixed and then viewed.

The mismatch repair system recognizes mismatched base pairs, removes a portion of the DNA strand containing the error, and then
Andre45 [30]

Answer:

It could lead to several later problems in the cell.

Explanation:

Removing a piece of DNA could severely affect the cell but it could also cause nothing. Depending on the part that is damaged, it could codify for a vital protein but it could also be an intron, which are pieces of DNA that don't codify for any protein. This has been recently researched and even though there are introns that could cause some serious trouble, most of them are an unknown matter to nowadays scientists. Anyway, a wrongly repaired sequence could end in a mutation that can potentially damage the cell and therefore the organism.

Example of how wildfires lead to secondary succession
faust18 [17]

Answer:

Explanation: a good example of how wildfires lead to secondary succession is in a oak and hickery forests and this is because wildfires will mostly burn out the vegetation and kill those animals however their nutrients would turn to ash

What is wrong with a bacterial cell if it cannot make protein
ivann1987 [24]

There are a variety of points in the transcriptional chain at which it is possible to disrupt protein synthesis in bacteria. Let’s enumerate just a few:

<span>There’s the initial point where DNA is transcribed into mRNA;<span>there’s the point where mRNA binds to the Ribosome complex;</span>there’s the point where tRNA-aminoacyl pair binds to the Ribosome according to the current codon being “read out” in the mRNA;there’s the point where the aminoacid transported by the tRNA is transferred to the growing protein chain; andthere’s the point where the protein synthesis is determined complete, and the Ribosome disengages and releases the newly-synthesized peptide chain.</span>

In each of these stages (and in some other, more subtle phases) there are possible points of disruption and there are specific disruptors; some of which are indicated in the aboveProtein synthesis inhibitor article.

Note, by the way, that the Ribosomes of Prokaryotes (bacteria) and Eukaryotes (cells with nuclei) aren’t identical, and therefore the inhibitors/disruptors that work for one type of cell may not (and usually don’t) work on the other type. That’s why we can take antibiotics targeted at bacteria with little to no fear of them interfering with our eukaryotic cells’ functions.

(This is a simplified, somewhat hand-wavy response. There is a lot more to say, mainly because biological systems are anything but simple. Nevertheless this should be enough to get you started in the general direction.)

Which region in the United States has the fewest thunderstorms per year?
Serga [27]

Answer:

Pacific Northwest

Explanation:

In the United States, the Pacific Northwest is the region that receives the least thunderstorm in a year. This is because of the location of the region. The region consists of states like Washington, California, Alaska, Hawaii, and Oregon. This region has few thunderstorms due to the nature of the region. The coldness of the pacific ocean means that there is more colder air on the earth. This suppressed the hot air. Thus, conventional rainfall; with thunder is less common. The other factor is the dryness of the region. The dry region has a lower humidity. This lesson the chance of charges air between the two fronts.
