Answer:
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.
Explanation:
The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.
Sunspots can be very large, up to 50,000 kilometers in diameter. They are caused by interactions with the Sun's magnetic field which are not fully understood. But a sunspot is somewhat like the cap on a soda bottle: shake it up, and you can generate a big eruption. Sunspots occur over regions of intense magnetic activity, and when that energy is released, solar flares and big storms called coronal mass ejections erupt from sunspots.
Answer:
Lacks the right key to unlock many cells.
Explanation:
Avian influenza (H5 N1) rarely transmitted from poultry to humans because it lacks the right key to unlock many cells in the upper respiratory tract so due to this action the virus is rarely transmitted to humans. Sometimes it is lethal to humans due to absence of antibodies for this type of virus. It is rarely spread from person to person due to inability to enters the other human body.
