Answer:
The North American fur trade was an industry and activity related to the acquisition, trade, exchange, and sale of animal furs in North America. Aboriginal peoples in Canada and Native Americans in the United States of various regions traded among themselves in the pre–Columbian Era. Europeans participated in the trade from the time of their arrival in the New World, extending the trade's reach to Europe. The French started trading in the 16th century, the English established trading posts on Hudson Bay in present-day Canada during the 17th century, while the Dutch had trade by the same time in New Netherland. North American fur trade was at its peak of economic importance in the 19th century, and involved the development of elaborate trade networks.
The fur trade became one of the main economic ventures in North America attracting competition among the French, British, Dutch, Spanish, and Russians. Indeed, in the early history of the United States, capitalizing on this trade, and removing the British stranglehold over it, was seen as a major economic objective. Many Native American societies across the continent came to depend on the fur trade as their primary source of income. By the mid-1800s changing fashions in Europe brought about a collapse in fur prices. The American Fur Company and some other companies failed. Many Native communities were plunged into long-term poverty and consequently lost much of the political influence they once had.

Answer:
X is the concentration of the substance being measured and Y is the response from the instrument that is being used to measure
Explanation:
A calibration curve is the plot of known concentration of substances where x is the increasing known concentration and Y is the response, typically "absorption" taken from the instrument that is used for measuring. This curve is then used to find out the concentration of the unknown substance by using it's absorbance and comparing it with the calibration curve. For example:
Concentrations and absorbance readings are as follows
0.5mg/mL=10 nm
1.0mg/mL=15nm
1.5mg/mL=20nm
2.0mg/mL=25nm
This data is plotted on a calibration curve. Next we measure the unknown substance the absorption is 20nm. We can suggest that the concentration is 1.5 mg/mL. If there are readings that fall inbetwen values then the formulat to calculate the right concentration would be y = mx + b, where m is the slope and b is the y-intercept.
Linear regression uses the modification of the slope formula y= a + bx to best see how the data of the water samples would fit on the slope of the calibration curve. X is the independent variable , b is the slope of the line and a is the y-intercept.
Extrapolation would be the action of calculating data that are outside the calibration curve, assuming the trend would continue.

Answer:
1. Both type A and type O
Explanation:
Blood genotype in humans follow the ABO system. The allele iA (type A) and iB (type B) are co-dominant but both dominant over the allele i (type O). This means that only a human with two i alleles will be type O.
Type A - iAiA or iAi (heterozygous)
Type B - iBiB or iBi (heterozygous)
Type O - ii
In this question, a man with a blood genotype IAi (type A) marries a woman with a blood genotype IAi (type A). Each of the parents will produce a gametes iA and i. Using these gametes in a punnet square (see attached image), offsprings with the following genotype will be produced: iAiA, iAi, and ii.
iAiA and iAi are type A while ii is type O. This means that both type A and type O could be expected in the children of this cross.
