Answer:

SEM ANSWER

Explanation:

Electron microscopy is a powerful tool in the field of microbiology. It has played a key role in the rapid diagnosis of viruses in patient samples and has contributed significantly to the clarification of virus structure and function, helping to guide the public health response to emerging viral infections. In the present study, we used scanning electron microscopy (SEM) to study the infectious cycle of SARS-CoV-2 in Vero E6 cells and we controlled some key findings by classical transmission electronic microscopy (TEM). The replication cycle of the virus was followed from 1 to 36 h post-infection. Our results revealed that SARS-CoV-2 infected the cells through membrane fusion. Particles are formed in the peri-nuclear region from a budding of the endoplasmic reticulum-Golgi apparatus complex into morphogenesis matrix vesicae. New SARS-CoV-2 particles were expelled from the cells, through cell lysis or by fusion of virus containing vacuoles with the cell plasma membrane. Overall, this cycle is highly comparable to that of SARS-CoV. By providing a detailed and complete SARS-CoV-2 infectious cycle, SEM proves to be a very rapid and efficient tool compared to classical TEM.

Letter M is in between L and N. So like this LMN and o is in between N and P. So like this NOP. So technically the difference from o to m is just one of N.

Answer 1: Difference b/w wet and dry earwax genes is due to switch of a single DNA unit i.e. single nucleotide polymorphism.

Answer 2: Earwax is important in many ways mainly it is a biological flypaper as it prevents dust and insects from entering the ear.

Answer 3: Genetics have proved that for those who sweat a lot and have armpit odor have wet earwax.

Answer 4: The wet type earwax is dominant one with honey brown or dark brown color while dry one is recessive.

Answer 5: As wet earwax is dominant trait, according to the given scenario the genotype of parent with wet earwax will be "WW" which when crossed with dry earwax parent will have all the offsprings with wet earwax.

Snowcat [4.5K]

Answer:

It is a true example of natural selection.

Explanation:

The dark colour mice lives in the dark soil of southeastern United States in large number as compared to other colour mice because this colour helps them to hide themselves from their predators in that dark soil while on the other hand, on light beaches of Florida light colour mice lives because this light colour also helps these mice in hiding from their enemy animals which is a true example of natural selection because dark colour mice can't survive in light colour beaches dude easily seen by their enemies and reduces its population by eating them.

If 30% of the bases in human DNA are A, (a) what percentage are C? (b) What percentage are T? (c) What percentage are
galina1969 [7]

Answer:

DNA is present as genetic material in all the living organism except some virus. DNA structure follows the Chargaff's rule in which states that the ratio of pyrimidines to purines is equal to 1.

So, amount of adenine will be equal to thymine. If adenine is 30% then thymine is also 30%. Total amount of DNA is 100%. Cytosine and thymine are also equal in the DNA molecule. The total amount of cytosine and guanine is 40%. The amount of cytosine is 20% and the amount of guanine is also 20%.

Thus, thymine is 30%, cytosine is 20% and guanine is 20%.
