Answer:
For the half of the radioisotopes of a certain kind to decay into more stable isotope, the amount of time required is called The Half Life.
Radiocarbon dating is typically used to date more recent objects like bones, cloth, wood, and plant fibers.
Sedimentary rocks cannot be accurately dated using isotope dating because this Rock type is formed through the sedimentation of different rocks and minerals fragment.
Using the principle of faunal succession, scientist can determine the age of rocks by the fossil flora and fauna embedded within them.
Explanation:
Carbon dating is a process which is done by the use of carbon 14 atom. It is a special type of atom which can easily help the scientist and expert to find out the age of the fossil of flora and fauna, rocks, animals, birds, etc.
Answer:
North American Countries
In North America, the nations of the United States and Canada own land areas in the Arctic. The only U.S. state containing land within the Arctic Circle is Alaska. In contrast, Canada’s polar regions are quite vast, encompassing about two-fifths of its entire land mass and two-thirds of its total maritime coastline. The historic residents of North America’s polar zones are the Inuits, who have made their livelihoods hunting and fishing in the harsh climate for more than 9,000 years, though many modernly work in oil fields and support villages.
European Countries
The exclusively European nations possessing land north of the Arctic Circle are Norway, Sweden, Finland, Iceland and Denmark. Although Denmark proper doesn’t lie within the polar zone, its largest self-governing overseas administrative division -- Greenland -- does. In addition to a portion of the Norwegian mainland, Norway’s Arctic territories also include the islands of Svalbard and Jan Mayen. Vikings hailing from Norway were the European polar region’s first explorers, establishing a permanent settlement on Iceland in the ninth century and a long-lived settlement in Greenland in the 10th century.

Answer:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female.
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease.
Explanation:
X linked dominant disorders are caused when the genes on the X chromosomes gets mutated. X linked dominant disorders phenotype is observed in each generation and males experience more severe symptoms of disorder as compared to a female. This disorder is never transmitted to male child by the father or in other way we can say that there is no male to male transmission. For example Fragile X syndrome
In X linked recessive disorder one copy of affected X gene is sufficient to cause the disease in males. In case of females both the X gene are required to be effected for causing disease. Males are more affected by this disorder as compared to females. For example - hemophilia
. This disorder is never transmitted to male child by the father just like the X linked dominant disorder or in other way we can say that there is no male to male transmission.
