b) I personally think both are pretty rad and have one of each as a pet.

c) Lastly, tortoises and turtles share a few major differences.

d) Tortoises shells are domed and thick, turtles have shells that are flat and thin

Answer 19

Question two.


Read the passage below. Then, answer the question that follows.

A Three-Point Turn

Chapter 1

"You know, hardly anyone ever needs to do a three-point turn anymore," said Justin, trying to help Becky calm down.

"Oh, so it's not a useful skill AND I am probably going to fail the driving test because I can't do it anyway," Becky said, raising her voice for emphasis. "That should make me feel like a million bucks when I flunk."

Justin was riding with Becky so she could take her driving test. He had volunteered for the job because he thought she would be less nervous with him than with their mom, but so far, he wasn't sure he was making any difference.

"Slow down, your turn is coming up here," he said, looking ahead.

"I know, I know," she replied, "I've been here before remember—the last time I flunked."

Justin was pretty sure if he had let her miss the turn, things would only have deteriorated further, but he wasn't sure he was fond of being the scapegoat for Becky's anxiety.

"Listen, you need to take a few deep breaths," he said, hoping he could help her at least relax a bit. "Being nervous won't help you with the three-point turn or anything else you have to do. Hey, did you just take that turn without your turn signal on?" This was going to be harder than he thought.

"Stop yelling at me," Becky replied, clearly frustrated, "I can't concentrate."

"Look, you need to stop and get yourself together here," Justin started. "It is not just about passing the driving test. I don't want to get in an accident, so pull into that parking lot."

Becky drove into the office building's parking lot where Justin was pointing. Justin knew they were less than a mile from the licensing office, and if she continued in this condition, he'd be having this same discussion three months from now when she tried the test again for the third time.

"You need to get a grip," he started after she put the car in park, "because you have studied and practiced driving all year. You know this stuff inside and out, backwards and forwards. What are you so nervous about?"

"I don't know, I don't know," Becky wailed, resting her head on the steering wheel. "I just get so tired of failing."

Listening quietly as Becky sobbed, Justin realized this was about much more than a driving test. He also knew if he didn't find a way to help Becky things would just get worse.

Which of the following statements best explains Justin's perspective about the situation?

a) Justin feels angry and aggravated that Becky is a better driver than him and decides to ruin her driving test.

b) Justin is understanding towards Becky's issues from start to finish and remains calm the entire time.

c) Justin is impatient and unaware of the reason for Becky's nervousness but slowly realizes what's really going on.

d) Justin realizes the situation with Becky is helpless and decides to give up on her

Question number one.

Which of the following lines from "The Gift of the Magi" uses indirect characterization to describe Jim?

a) "It was like him. Quietness and value, the description applied to both."

b) "Jim was never late."

c) "Out of his trance Jim seemed quickly to awake. He enfolded his Della."

d) "Poor fellow, he was only twenty-two, and to be burdened with a family!"

Answer 23

Bot?

Answer 24

Hello! Of course, feel free to ask your question.

Answer 25

Based on the information provided, the correct statement would be:

b) Neither idea could be scientific.

A scientific idea should be testable and produce consistent results when tested by different scientists. However, Jim's idea is non-testable, meaning it cannot be scientifically investigated or verified. Similarly, Tom's idea giving different results to different scientists implies inconsistency, which also goes against the principles of scientific inquiry. Therefore, neither Jim's nor Tom's ideas meet the criteria for being scientific.

Answer 27

The correct answer is:

d) Natural phenomena

Science is primarily concerned with explaining and understanding the natural world through empirical observation, experimentation, and logical reasoning. It aims to provide explanations for natural phenomena, such as physical processes, biological systems, and the behavior of matter and energy. Science does not directly address moral values, biased opinion, or the meaning of life, as those topics fall into the realms of ethics, subjective perspectives, and philosophy.

Answer 28

Absolutely! I'm here to assist you with any questions you have. Please go ahead and ask your third question.

Answer 29

The correct answer is:

c) Analyze data and draw conclusions

In the scientific method of investigation, after asking a question, conducting background research, and constructing a hypothesis, the next step is to test the hypothesis through an experiment. Following the experiment, data is collected, analyzed, and conclusions are drawn based on the results. Therefore, analyzing data and drawing conclusions typically occurs as one of the final steps in the scientific method.

Answer 31

Based on the information provided, Melanie performed the step of the scientific method known as:

b) Testing with an experiment.

Melanie conducted an experiment by adding different fertilizers to the plants and observing the effect on their growth. By varying the conditions (adding different fertilizers), while keeping other factors constant, she was able to test the effect of the fertilizers on plant growth. This step involves manipulating variables and collecting data to draw conclusions about the relationship between the variables being tested.

Answer 32

The correct answer is:

c) Quantity of matter in an object.

Mass is a measure of the amount of matter present in an object. It represents the measurement of inertia, which is the resistance of an object to changes in its motion. Mass is an intrinsic property of an object and is usually measured in units such as kilograms or grams. It is different from volume (how much space an object takes up), density (mass per unit volume), and weight (force of gravity acting on an object).

Answer 33

Based on the information given, the correct answer is:

b) Quantity A, because it changes gravitational pull.

The force exerted on an object depends on the gravitational pull acting on it. When an astronaut is on Earth, Quantity A has a value of 735 units, but when on Mars, it decreases to 75 units. This change in value indicates that Quantity A is influenced by the gravitational pull, as it decreases when the astronaut moves to a location with a different gravitational force. Therefore, Quantity A measures the force exerted on the astronaut, not Quantity B.

Answer 34

The correct answer is:

c) Increase in the amount of matter present in the object.

The mass of an object is a measure of the quantity of matter it contains. Therefore, if there is an increase in the amount of matter present in the object, the mass will also increase. This is regardless of any changes in gravitational pull, which do not directly affect the mass of an object. Thus, an increase in the amount of matter is what causes an increase in the mass of an object.

Answer 35

The correct answer is:

a) Mass divided by volume.

Density is calculated by dividing the mass of an object by its volume. Mathematically, it can be represented as Density = Mass/Volume. The units of density are typically represented as mass per unit volume, such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). Therefore, option a) Mass divided by volume, is the correct way to calculate density.

Answer 36

To calculate density, you divide the mass of the object by its volume. Let's calculate the density of the object using the given values:

Density = Mass / Volume

Density = 8.5 g / 17 mL

Density = 0.5 g/mL

Therefore, the density of the object is:

b) 0.5 g/mL

Answer 37

Density is calculated by dividing the mass of an object by its volume. To compare the densities of different blocks, we need to calculate their densities using the given measurements.

Density = Mass / Volume

Let's calculate the densities for each block:

Block A:
Density = 2 kg / (1 cm * 2 cm * 5 cm) = 0.2 g/cm³


Block B:
Density = 2 kg / (5 cm * 2 cm * 1 cm) = 0.2 g/cm³


Block C:
Density = 3 kg / (1 cm * 2 cm * 5 cm) = 0.3 g/cm³

From the calculations, we can see that:

c) The density of Block A is equal to the density of Block B.

Block A and Block B have the same density of 0.2 g/cm³. Therefore, option c is correct.

Answer 38

The correct answer is:

b) Magnetism

An intensive property is a property that does not depend on the amount or size of a substance. It remains the same, regardless of the quantity or extent of the substance being observed. In this case, magnetism is an example of an intensive property because it does not depend on the amount or size of the object. It can be present or absent in an object, but the strength of the magnetism itself is independent of the size or quantity of the substance.

Mass (a), shape (c), and volume (d) are examples of extensive properties because they do depend on the amount or size of the substance.

Answer 39

Solubility refers to the ability of a substance to dissolve in a particular solvent. In this case, we are comparing the solubility of the given samples in water. To determine which samples have the same solubility, we need to identify the substances that will fully dissolve in water.

From the given samples:

Sample A: 5 g of salt
Sample B: 8 g of sand (typically insoluble in water)
Sample C: 8 g of sugar
Sample D: 5 g of sugar

Based on this information, we can conclude that:

a) Sample A and Sample C have the same solubility since both salt and sugar are typically soluble in water.

So, the correct answer is a) Sample A and Sample C.

Answer 40

Based on the information provided, we can determine the densities of the substances and compare them to the plastic bead:

From top to bottom:

1. Oil (density not specified)
2. Soap water
3. Milk

Given the position of the plastic bead, it is settling on the layer separating the oil and soap water. Therefore, we can infer that the plastic bead is denser than the soap water but less dense than the oil.

Based on these comparisons, the best answer is:

c) The plastic bead is denser than soap water and milk, but oil is denser than the plastic bead.

This statement correctly describes the relative densities of the substances involved.

Answer 41

Of course! I'll do my best to help you with questions related to language arts. Please go ahead and ask your language arts question, and I'll assist you.

Answer 42

To revise the paragraph for coherence, Anya should remove the sentence that does not contribute to the overall flow and cohesion of the paragraph. In this case, the sentence that is not directly related to the comparison between tortoises and turtles is:

b) I personally think both are pretty rad and have one of each as a pet.

This sentence introduces a personal opinion that does not add relevant information to the topic of the paragraph, which is the differences between tortoises and turtles. Removing this sentence would improve the coherence and focus of the paragraph.

Answer 43

Based on the passage, the best explanation of Justin's perspective about the situation is:

c) Justin is impatient and unaware of the reason for Becky's nervousness but slowly realizes what's really going on.

Throughout the passage, Justin tries to help Becky calm down and give her advice during the driving test. He initially doesn't understand the underlying reasons for Becky's nervousness and gets frustrated. However, as the conversation progresses, he starts to realize that her anxiety runs deeper and that this goes beyond just the driving test. This understanding is reflected in his realization that he needs to find a way to help Becky, as he knows things will only get worse if he doesn't.
