Which microscope would be used to observe surface structure of corona virus?
ElenaW [278]

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.

A student drew the diagram below to model the process of binary fission, which is a type of asexual reproduction.
Leno4ka [110]
The answer would be: <span>Binary fission involves a single parent cell, so there is only one set of genetic information that can be duplicated and passed on to the daughter cells.

If you see the picture, it is clear that there is only 1 parent involved in binary fission. This will exclude the first and third option. 
The genetic duplicated before splitting, so the cells should have an equal number of parent genetic material, not halves. This will exclude the second option.
