Answer:    Decreased levels of melatonin

Explanation:  Melatonin is a substance that is excreted at night and by which the brain sends signals that one should sleep, that is, a man / woman is feeling sleepy. When melatonin secretion decreases, the alertness increases, as is the case with Colby. Melatonin levels decrease at the base of the brain signal regardless of whether or not Colby slept enough the previous night. Feeling tired will induce some other receptors and consequent signals from the brain, but a natural decrease in melatonin throughout the day occurs normally.

Elenna [48]

Answer: Hebbian learning

Explanation: This is a type of learning which involves strengthening connections between neurons which work together. The repeated exposure to a particular stimulus can strengthen connections within a distinctive subset of cortical neurons, and this subset can provide a reliable basis for identifying the stimulus that is activating them.

It has been proven that even when an individual encounters an incomplete version of a familiar stimulus with only some of the subset of neurons representing that familiar stimulus activated at first, the connections already established through repeated coactivity will produce results that complete the familiar pattern.

Which option best completes the following sentence? Within an economy, ____________ and ____________ exchange goods and services
Maslowich

The correct answer is - B. consumers/producers.

Within an economy, of any type, there's an exchange of goods and services between the producers and consumers. In order for something to get on the market someone has to produce it or provide it, be it a good or a service, and that good or service is used by someone, thus the consumers.

While the producers make certain thing, the consumers buy it or exchange it. Depending on the type of economy, it can be money in exchange for a good or service (which is the dominant type by far), or it can be a good for good, or a service for service, which has been a dominant type in the past, but not anymore.

How do you think the Northwest Ordinance affect Native Americans
scoundrel [369]
<span>Native Americans in Ohio, who were not parties, refused to acknowledge treaties signed after the Revolutionary War that ceded lands north of the Ohio River inhabited by them to the United States. In a conflict sometimes known as the Northwest Indian War, Blue Jacket of the Shawnees and Little Turtl of the Miamis formed a confederation to stop white expropriation of the territory. After the Indian confederation had killed more than 800 soldiers in two battles the worst defeats ever suffered by the U.S. at the hands of the Indians President Washington assigned General Anthony Wayne command of a new army, which eventually defeated the confederation and thus allowed European-Americans to continue settling the territory. </span>
