Which country's colonists maintained a profitable fur trade in North America

Tom [10]

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:

the temperature of water drops and the density of it goes down as well.

Explanation:

The higher the altitudes, the lower the temperature.

At high altitudes, molecules tend to be more spread out, so the density of the molecules decrease.

A female fly that has miniature wings and sepia eyes is crossed with a male that has normal wings and is homozygous for red eyes

Eduardwww [97]

Answer and Explanation:

The gene that expresses the size of the wing is X-linked. The dominant allele expresses long wings, XM, while the recessive allele expresses miniature wings, Xm.

The gene that expresses the color of the eyes is autosomal. The dominant allele expresses red color, S, and the recessive allele expresses sepia color, s.

A female fly that has miniature wings and sepia eyes (XmXm ss) is crossed with a male that has normal wings and is homozygous for red eyes (XMY SS).

The F1 are intercrossed to produce the F2.

100% of the females (1/2 or 50% of the progeny) are long-winged and red-eyed

100% of the males (1/2 or 50% of the progeny) are miniature.winged and red-eyed.

F2) 8/16=4/8=1/2 or 50% of the progeny are females and the other 1/2 or 50% are males

Females (8/16):

3/8 of the females are long-winged and red-eyed, XMX- S-

1/8 of the females are long-winged and sepia-eyed, XMX- ss

3/8 of the females are miniature-winged and red-eyed, XmXm S-

1/8 of the females are miniature-winged and sepia-eyed, XmXm ss

Males (8/16):

3/8 of the males are long-winged and red-eyed, XMY S-

1/8 of the males are long-winged and sepia-eyed, XMY ss

3/8 of the males are miniature-winged and red-eyed, XmY S-

1/8 of the males are miniature-winged and sepia-eyed, XmY ss

Note: The symbol "-" means that in its place might be a recessive allele or a dominant allele. For example, S- means that it might be SS or Ss.

Research how the body uses feedback mechanism to decrease the heart rate after exercise. what specifically happens in the body t

maw [93]

A negative feedback loop works by adjusting an output, such as heart rate, in response to a change in input, such as blood pressure. A basic loop consists of a receptor, a control center and an effector. If you are at rest and your blood pressure increases, pressure receptors in your carotid arteries detect this change in input and send nerve impulses to the medulla of your brain, or control center. This signals the brain to reduce nerve impulses that stimulate your heart muscle, an effector, to contract. Your heart contracts more slowly and your output, or heart rate decreases, causing your blood pressure to decrease to within target levels.
