Question 1

Which picture represents the second insect phase shown?

TheoryPractice · Accepted Answer

Image A. Image A is a diagram of the larval stage of the insect. The insect life cycle moves from egg (shown in Image D), to larva (shown in Image A), to pupa (shown in Image B), then finally to adult (shown in Image C).

Question 2

By which enzyme is trypsinogen, an enzyme secreted by the pancreas, activated into trypsin in the duodenum?

TheoryPractice · Accepted Answer

enterokinase. Enterokinase is the enzyme responsible for activating trypsinogen into trypsin in the duodenum. Trypsinogen is a precursor enzyme secreted by the pancreas, and it needs to be activated in order to carry out its functions. Once enterokinase cleaves a specific peptide bond in trypsinogen, it becomes active as trypsin.

Option B) pepsin is incorrect because pepsin is a gastric enzyme that functions in the stomach, not the duodenum. Pepsin helps break down proteins in the stomach, but it does not play a role in activating trypsinogen.

Option C) hydrochloric acid is incorrect because hydrochloric acid is an acid secreted by the stomach, not the pancreas. While hydrochloric acid does play a role in digestion, it does not directly activate trypsinogen into trypsin.

Option D) protease is incorrect because "protease" is a general term for enzymes that break down proteins. While trypsin is indeed a protease, it is specifically activated by enterokinase, not by a generic protease enzyme.

In summary, enterokinase is the specific enzyme responsible for activating trypsinogen into trypsin in the duodenum.

Question 3

Which is the best definition for the connotation of a word?

TheoryPractice · Accepted Answer

Underlying meanings we associate with a word. Denotation is the literal definition of a word. Connotation is the figurative meaning of a word, the global and personal associations words carry.

Question 4

The Corps of Discovery Expedition, later called the Lewis and Clark Expedition, had both scientific and commercial objectives. Meriwether Lewis and William Clark were commissioned by President Thomas Jefferson to study the flora, fauna, geology, cartography (map making), topography (land features) and limnology (study or fresh water systems) of the interior of the northern United States from coast to coast.

The goal of these scientific objectives was to learn as much as possible about how to use these things for commercial or economic purposes. The expedition lasted from 1804-1806 and it produced a significant wealth of knowledge about a little known swath of the entire continent.

What was the primary purpose of the Lewis and Clark Expedition?

TheoryPractice · Accepted Answer

To carry out scientific studies on a region to learn how it could be exploited.. The primary purpose of the Lewis and Clark Expedition was to carry out scientific studies on a region to learn how it could be exploited. The Lewis and Clark Expedition had both scientific and commercial objectives. The goal of the scientific objectives was to learn as much as possible about how to use these things for commercial or economic purposes, which also means how to exploit them.

Question 5

Sonja, I think it’s time for us to open a new location. We’ve been talking about doing it forever and I’m afraid that if we don’t do it now, we’ll never do it.

I know it’s a risky move, but the only way our business is going to grow is if we take calculated risks.

Business has never been better, and our focus group data shows that people in Springdale would love to have one of our stores in their mall.

If we do this right, we can be twice as profitable as we are now in three years. Let me know what you think.

Thanks, Gabriela

PS: We can even announce the expansion after that Channel 4 puff piece airs to take advantage of the attention we’ll be getting!

Which of the following best captures the author’s purpose?

TheoryPractice · Accepted Answer

Improve a successful business by opening a second location.. Because the author’s first sentence mentions opening a new location. She also writes that, “business has never been better,” which refutes answer choice (A), and also points off that they have already done the research necessary to prepare for this expansion, which refutes answer choice (D).

Question 6

We have said that argumentation is the art of producing in the mind of someone a belief in something in which we wish him to believe.

Now it is obvious that this can be accomplished in different ways. Perhaps the most common method of attempting to bring someone to believe as we wish is the oral method. On your way to school you meet a friend and assert your belief that in the coming football game the home team will win. You continue: "Our team has already beaten teams that have defeated our opponent of next Saturday, and, moreover, our team is stronger than it has been at any time this season." When you finish, your friend replies: "I believe you are right. We shall win."

You have been carrying on oral argumentation.

If, when you had finished, your friend had not agreed with you, your effort would have been none the less argumentation, only it would have been unsuccessful. If you had written the same thing to your friend in a letter, your letter would have been argumentative.

Suppose your father were running for an office and should make a public speech. If he tried to make the audience believe that the best way to secure lower taxes, better water, and improved streets would be through his election, he would be making use of oral argumentation. If he should do the same thing through newspaper editorials, he would be using written argumentation.

Argumentation, then, may be carried on either in writing or orally, and may vary from the informality of an ordinary conversation or a letter to a careful address or thoughtful article.

Based on the passage, what does the "variance" tell us about the responses?

TheoryPractice · Accepted Answer

Variance tells us the spread of values within the sample.. Based on the passage, the "variance" tell us the spread of values within the sample; a high variance means there were a lot of different values given by respondents.

Question 7

Careering madly in a motor car behind a herd of antelope fleeing like wind-blown ribbons across a desert which isn't a desert, past caravans of camels led by picturesque Mongol horsemen, the Twentieth Century suddenly and violently interjected into the Middle Ages and should be contrast and paradox enough for even the most sophisticated sportsman. I am a naturalist who has wandered into many of the far corners of the earth. I have seen strange men and things, but what I saw on the great Mongolian plateau fairly took my breath away and left me dazed, utterly unable to adjust my mental perspective.

When leaving Peking in late August, 1918, to cross the Gobi Desert in Mongolia, I knew that I was to go by motor car. But somehow the very names "Mongolia" and "Gobi Desert" brought such a vivid picture of the days of Kublai Khan and ancient Cathay that my clouded mind refused to admit the thought of automobiles. It was enough that I was going to the land of which I had so often dreamed.

In what narrative form is the passage written?

TheoryPractice · Accepted Answer

First person singular. The use of the pronoun "I" in the passage indicates that the author is using a first person singular narrative. He is retelling his adventures while traveling through Mongolia in a motor car. With first person plural, typically "we" is used.

Question 8

Choose the coordinating conjunction that would correctly complete the blank in the following sentence:

I've been cleaning the house all day, ________ I'm going to rest now.

TheoryPractice · Accepted Answer

So. The second phrase follows the first, making 'so' the coordinating conjunction that is suitable.

Question 9

Select the option that corrects any errors in the underlined portion(s). If there are no errors, please choose "No change is necessary."

Did you get your (A) inoculation against malaria before you left for Africa? It was necessary since you went to a (B) foriegn country. Weren’t you (C) grateful that you did?

TheoryPractice · Accepted Answer

foreign. This word is one that deviates from the “i before e” rule. There is only one “n” in “inoculation” and “grateful” is not spelled by beginning with “great.”

Question 10

Select the option that rectifies the error using a comma, semicolon, dash, or colon.

The weather is a factor in ski jumping a lack of snow could be dangerous.

TheoryPractice · Accepted Answer

The weather is a factor in ski jumping; a lack of snow could be dangerous.. When two closely related independent clauses are not joined by a coordinating conjunction, use a semicolon between them. Do not capitalize the first word in the second independent clause. Exercise caution to avoid creating fragments and run-on sentences when using commas, semicolons, and colons.
