Explain how the plague was spread to Europe and the symptoms associated with the plague.

The disease, caused by a bacillus bacteria and carried by fleas on rodents, originated in central Asia and was taken from there to the Crimea by Mongol warriors and traders. The plague entered Europe via Italy, carried by rats on Genoese trading ships sailing from the Black Sea.Yersinia causes three types of plague in humans: bubonic, pneumonic, and septicemic. Although there is DNA evidence that Yersinia was present in victims of the Black Death, it is uncertain which form the majority of the infection took. It is likely that all three played some role in the pandemic.

Bubonic plague causes fever, fatigue, shivering, vomiting, headaches, giddiness, intolerance to light, pain in the back and limbs, sleeplessness, apathy, and delirium. It also causes buboes: one or more of the lymph nodes become tender and swollen, usually in the groin or armpits.

Pneumonic plague affects the lungs and causes symptoms similar to those of severe pneumonia: fever, weakness, and shortness of breath. Fluid fills the lungs and can cause death if untreated. Other symptoms may include insomnia, stupor, a staggering gait, speech disorder, and loss of memory.

Septicemic plague is an infection of the blood. Its symptoms include fatigue, fever, and internal bleeding.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
