Answer 1

Let's compare the diameters of platelets and red blood cells based on the values you provided:

• Diameter of a platelet: \( 2.33 \times 10^{-6} \) m
• Diameter of a red blood cell: \( 0.0000075 \) m, which can be expressed as \( 7.5 \times 10^{-6} \) m

Now, to find out which one has a bigger diameter and by how much, we can convert \( 0.0000075 \) m into scientific notation:

• Diameter of a red blood cell: \( 7.5 \times 10^{-6} \) m
• Diameter of a platelet: \( 2.33 \times 10^{-6} \) m

Now, we subtract the diameter of the platelet from that of the red blood cell to find the difference:

\[ 7.5 \times 10^{-6} - 2.33 \times 10^{-6} = (7.5 - 2.33) \times 10^{-6} = 5.17 \times 10^{-6} , \text{m} \]

Therefore, a red blood cell has a bigger diameter than a platelet by \( 5.17 \times 10^{-6} \) m.

The correct response is: A red blood cell has a bigger diameter than a platelet by 5.17×10−6 m.

Answer 2

Which of the following inferences about the Foreman is best supported by the passage below (paragraph __)?

FOREMAN: All right. Now you gentlemen can handle this any way you want to. I mean, I’m not going to have any rules. If we want to discuss first and then vote, that’s one way. Or we can vote right now to see how we stand. [He pauses and looks around.] Well, that’s all I have to say.
Answer choices for the above question

A. He does not have strong feelings about his leadership role.

B. He wishes to nominate another Foreman to lead the group.

C. He believes that the defendant did not receive a fair trial.

D. He hopes that the jury will vote first and get it over with as quickly as possible.

Answer 3

The best inference about the Foreman, based on the passage provided, is:

A. He does not have strong feelings about his leadership role.

This inference is supported because the Foreman states, "I’m not going to have any rules," indicating a lack of a rigid or authoritative approach to his leadership role. He is giving the jurors the freedom to choose how they want to proceed, which suggests he is not overly invested in enforcing a particular structure or approach.

The other options (B, C, and D) are not supported by the provided text.

Answer 4

Instructions Read the question carefully and select the best answer. The interaction between the jurors in the jury room most strongly suggests that . Answer choices for the above question A. those with power often take advantage of the weak B. the majority of people are motivated by revenge C. most people will stand up to bullies D. all jurors in this country want to deliver a fair verdict

Answer 5

The best answer based on the interaction between the jurors in the jury room is:

A. those with power often take advantage of the weak.

This choice reflects common themes in group dynamics and power struggles, where individuals with stronger personalities or positions may dominate the conversation or decision-making processes, potentially overshadowing the opinions of others who may feel less empowered or confident to speak up.

The other options don't align as closely with the dynamics typically observed in such situations:

• B suggests a motivation for revenge, which isn't universally applicable to juror interactions.
• C implies a consistent willingness to confront bullies, which may not always be the case in reality.
• D suggests that all jurors desire fairness, but the dynamics can sometimes hinder that ideal, especially if power imbalances exist.

Hence, option A is the most applicable inference regarding jurors' interactions.
