Explanation:
Yellow fever is an acute viral infection transmitted by mosquitoes in tropical sub-Saharan Africa and in the rainforests of tropical South America. Risk to travelers is very low, but high death rates may occur in unvaccinated travelers. Vaccination is about 100% protective in healthy travelers; however, no treatment for the disease exists
here is some more stuff that may help you..
Yellow fever (YF), a viral infection that occurs in tropical sub-Saharan Africa and the rainforests of tropical South America, is acquired through the bite of an infected mosquito.
Risk is low to very low in travelers and depends on the time of year and itinerary. Risk is 10 times greater in Africa than it is in South America.
Symptoms include fever, chills, and muscle aches, which may progress to vomiting, upper abdominal pain, and bleeding.
Consequences of infection in unvaccinated travelers include mental confusion, coma, shock, and multiorgan failure. Death may occur in up to 90% of those infected.
Prevention includes wearing long sleeves and long pants as well as observing personal protective measures against mosquito bites.
YF vaccine is given as a single dose at least 10 days prior to travel (for personal protection or to meet an entry requirement). Some YF-free countries may require vaccination only for travelers coming from another country with risk of YF transmission.
Vaccine side effects are most commonly injection-site reactions. Serious side effects are rare but may include brain inflammation in young children, neurological reactions, and multiple organ dysfunction (first time vaccinees only, mainly persons 60 years and older).
Duration of vaccine protection is long term; a booster dose for personal protection is recommended every 10 years only for persons who will be visiting a high-risk area, travel frequently to risk areas, or may have had an inadequate response to a previous YF vaccination.
Answer:
We know that speed defines the rate at which the position of a given object changes as time passes.
Here we must use the relation:
distance = speed*time.
With this, we will find that the sloth needs 25 minutes to travel the given distance.
Now let's see how we get that value:
We know that the length of the football field is 300ft, then:
distance = 300ft.
We also know that the sloth can travel a distance of 60ft in 5 minutes, then using the above relation we can find that the speed of the sloth is:
speed = distance/time = 60ft/5min = 12 ft/min
Now we know the distance that the sloth must travel and the speed of the sloth, then we can solve the general relation for the time:
time = distance/speed =
This means that the sloth will travel the length of a football field in 25 minutes.
Explanation:
Samuel de Champlain
Known as the Father of Canada or the Father of New France, Samuel de Champlain was a major contributor to the development of a French presence in North America. He was born in the village of Brouage on the Bay of Biscay and received his maritime education from his father, a ship’s captain. Little else is known about his early years.
Champlain served briefly in the French army before joining his uncle on a series of trading voyages to Panama, Mexico and the West Indies. His written account of his adventures included early speculation about the feasibility of constructing a canal through Central America. King Henry IV was impressed by young Champlain and provided him with a small pension.
In 1603, Champlain accompanied Francis Gravé, Sieur du Pont on a voyage to the Rivière de Canada (St. Lawrence River). The purpose of this venture was to develop the fur trade, but Champlain spent much of his time exploring his surroundings. He pushed up the St. Lawrence as far as the rapids near what would become Montréal, an area visited nearly 70 years earlier by Jacques Cartier. Champlain viewed Niagara Fallsand held to the belief that westward exploration would yield an opening to Asia.
A second voyage began in 1604 and resulted in a small settlement on an island in the St. Croix River (at the present-day boundary between New Brunswick and Maine). Champlain and his party spent a miserable winter there before relocating to Port Royal in the spring. Nearly two years were spent in exploring coastal lands to the south; it appears that Champlain probably ventured as far as Cape Cod. Lack of support from home led to widespread discouragement among the settlers; many accompanied Champlain back to France.
In 1608, Champlain returned to North America with the Sieur de Monts, but on this voyage they hoped to find more hospitable conditions than those encountered on Acadia. A small settlement was established at what would become Québec. The anticipated fur trade with the local natives was slow to develop and the first winter was harsh beyond all expectations; only eight of 24 settlers survived. Champlain eventually managed to forge tight bonds with the neighboring Algonquin and Huron. In 1609, he participated with them in a raid against their traditional enemy, the Iroquois. Using firearms, a frightening novelty to the Iroquois, Champlain succeeded in killing two opposing chiefs and making lasting allies of the Algonquin and Huron. On this foray, Champlain may have been the first European to see Lake Champlain, which he named for himself. He then returned to France for supplies and reinforcements.
Champlain returned to New France briefly in 1610. He was wounded while fighting the Iroquois and went back to France for treatment. In later years, he traveled across the Atlantic on a number of occasions in his efforts to keep the struggling colony alive. Pressing European affairs often diverted the attention of French officials and Champlain was forced to make his case for the colony repeatedly.
Warfare erupted between England and France in 1626. North America became one of the theaters of operations and was characterized by successful English forays against a number of settlements in New France. By 1628, the English had succeeded in cutting off Québec from outside contact. Champlain and the beleaguered settlers held out for a year, but were forced to surrender when provisions ran out. Champlain was taken into custody and briefly detained in England. Peace was achieved in 1632 and Québec was returned to French hands. Champlain returned to New France the following year, was warmly greeted and spent his remaining days strengthening the colony.
More than any other factor, Champlain’s determination was responsible for the success of New France. He initiated a solid relationship with native tribes, particularly the Huron, and was a witness to the growing rivalry in North America between France and England.
