This would directly affect the epidermis because blisters will develop within the surface of the skin. Having blisters on the epidermis will decrease the function of the skin to be an effective barrier to disease. This is because blisters are open wounds that are prone to infection. As infection passes through these openings, it will affect the dermis and the other layers of the skin. Bullae is actually an auto-immune skin disease.
I believe that the correct match will be;
Prominences- A
Sunspots - B
Solar flares - C
Convection -D
Prominence is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona.
Sunspots are darker, cooler areas on the surface of the sun in a region called the protosphere. Solar flares are large eruptions of electromagnetic radiation from the sun lasting from minutes to hours.
Runner B took about 13.3 mins per mile while Runner A took about 15 mins per mile so runner be ran faster
