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.
What are his observations? We can’t answer this without knowing his observations if those are the conclusions. Please provide the rest of the information and I can answer.
Answer:
Answer is D. Tension
Explanation:
Tension headache is a type of headache that can be described as feeling of dull or moderate pain in the head, which can be inform of a tightness around the head and the neck.Tension headache is also known as stress headache.
It has been discovered that, various activities like driving for a long period of time, staring to a computer for a long period and exposure to cold temperature, can cause tension headache.
The following activities can be developed to reduce or avoid tension headache.
* Drinking a lot of water.
* Regular exercise.
* Sleeping very well
* Limiting stress
* Eating foods like almond and walnut.
In this case, the complaint of a 'pressure' type headache to the back of the head and neck by the man, was a typical feeling ,synonymous to tension headache.
The answer is D; homeostasis allows the maintenance and regulation of stability and constancy that is needed to properly function. It is found in cells, tissues and organisms,
