As you study two closely related predatory insect species, the two- spot and the three- spot avenger beetles, you notice that ea

ch species seeks prey at dawn in areas without the other species. However, where their ranges overlap, the two- spot avenger beetle hunts at night and the three- spot hunts in the morning. When you bring them into the laboratory and isolate the two different species, you discover that the offspring of both species are found to be nocturnal. You have discovered an example of _____.

Answer:

Character displacement.

Explanation:

Character displacement is an evolutionary divergence that occurs to two similar type of species that live or inhabit an enviroment. As with all living organisms, natural selection favors those who can change, adapt, evolve in any way (could be a behavior, morphological or physiological change) to reduce their competitive pressure for resources, increasing their chance for survival. Another very interesting fact is that, even if character displacement occurs in many species living in the same enviroment, if said enviroment is changed (just like in the example) the displacement will be undone. As in the exercise, when in the enviroment both types of beetles seek prey without the other. But, in the laboratory, both are nocturnal. This is a trait of character displacement in which if the enviroment factor is changed, it might dissapear.

Do you need the answer from the quadratic formula? if so:
\frac{b+/- \sqrt{-b^2-4(a)(c)} }{2(a)}
x^2=a
-3x=b
-18=c

\frac{3+/- \sqrt{3^2-4(1)(-18)} }{2(1)}

\frac{3+/- \sqrt{9+72} }{2}

\frac{3+/- \sqrt{81} }{2}

\frac{3+/- 9 }{2}

\frac{3+9}{2}=  \frac{12}{2} =6

\frac{3-9}{2} = \frac{-6}{2} =-3

Your answer would then be 6 and -3

Explanation:

Trade was also a boon for human interaction, bringing cross-cultural contact to a whole new level. When people first settled down into larger towns in Mesopotamia and Egypt, self-sufficiency – the idea that you had to produce absolutely everything that you wanted or needed – started to fade. A farmer could now trade grain for meat, or milk for a pot, at the local market, which was seldom too far away. Cities started to work the same way, realizing that they could acquire goods they didn't have at hand from other cities far away, where the climate and natural resources produced different things. This longer-distance trade was slow and often dangerous but was lucrative for the middlemen willing to make the journey. The first long-distance trade occurred between Mesopotamia and the Indus Valley in Pakistan around 3000 BC, historians believe. Long-distance trade in these early times was limited almost exclusively to luxury goods like spices, textiles, and precious metals. Cities that were rich in these commodities became financially rich, too, satiating the appetites of other surrounding regions for jewelry, fancy robes, and imported delicacies. It wasn't long after that trade networks crisscrossed the entire Eurasian continent, inextricably linking cultures for the first time in history. By the second millennium BC, former backwater island Cyprus had become a major Mediterranean player by ferrying its vast copper resources to the Near East and Egypt, regions wealthy due to their own natural resources such as papyrus and wool. Phoenicia, famous for its seafaring expertise, hawked its valuable cedarwood and linens dyes all over the Mediterranean. China prospered by trading jade, spices, and later, silk. Britain shared its abundance of tin.

Answer:

B.F Skinner´s studies led him to the idea that children learn language through operant conditioning. Applying positive reinforcement when a child uses a word correctly helps him to learn the association between that word and its meanings.

Explanation:

Celebrating a child for producing sounds that are close to a word reassures him and makes him repeat it. On the other hand, ignoring sounds that aren´t similar to any words makes the child forget about them. Based on his theory, Skinner developed a teaching process for language development based on the reinforcement of correct use of language. Let's imagine a child that says the word "milk" or a sound similar to that word. If he´s given milk after that and praised about it, he will learn the relationship between the word and its meaning and develop a language based on that information.
