This infectious viral disease has many symptoms, from chills, fever, and aching muscles to coughing and sneezing to nausea and vomiting. it is highly infectious; many people get a injection to protect them from this disease. it is transmitted through the air, from person to person, by coughing and sneezing. this infectious disease is a) asthma. b) the flu. c) strep throat. d) the common cold.

The correct answer is B. The Flu

Explanation:

Influenza or flu is a common viral disease that develops in the respiratory system, although some types can develop in the digestive system. Due to this, flu symptoms are many and can include fever, coughing, sneezing, vomiting or aching muscles. Additionally, this is usually passed from one person to another or through objects that have been in contact with the virus but can be prevented through the use of flu vaccines that usually protect people from different types of flu viruses as well as certain measures such as washing your hands or avoid crowded places. Thus, it is the flu the infectious disease described.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
