A scientist conducted an experiment to determine how the amount of salt in a body of water affects the number of plants that can live in the water. In this experiment the dependent variable is

In this experiment, the dependent variable is **the number of plants in the water**. The dependent variable is what the scientist measures in the experiment, and it is affected by changes in the independent variable, which in this case is the amount of salt in the water.

Which claim is BEST supported by the data? HINT: Pay attention to both graphs

Which claim is BEST supported by the data? HINT: Pay attention to both graphs

As annual precipitation increases, the populations of species A and B decrease.

As annual precipitation increases, the populations of species A and B increase.

As annual precipitation increases, the populations of species A increases while species B decreases.

As annual precipitation increases, the populations of species A decreases while species B increases.

To determine which claim is best supported by the data, one would need to analyze the trends shown in both graphs regarding the populations of species A and B in relation to annual precipitation.

Without seeing the actual graphs, I cannot give you a definitive answer. However, you can evaluate the claims based on the trends observed in the graphs:

1. **Claim A:** As annual precipitation increases, the populations of species A and B decrease.
2. **Claim B:** As annual precipitation increases, the populations of species A and B increase.
3. **Claim C:** As annual precipitation increases, the populations of species A increase while species B decreases.
4. **Claim D:** As annual precipitation increases, the populations of species A decrease while species B increases.

To choose the best-supported claim:
- Look for trends where both species are increasing or decreasing together.
- Observe whether one species increases while the other decreases.
- Identify any contrasting trends based on variations in precipitation.

The claim that aligns most closely with the observed data in the graphs would be the best-supported one. Could you provide the trends you see in the graphs? That would allow for a more accurate assessment.

Which graphic representation would be the best way for Linda to display data from the three trials she tested?

Which graphic representation would be the best way for Linda to display data from the three trials she tested?

stem and leaf plot

bar graph

line graph

pie graph

The best type of graphic representation for Linda to display data from the three trials she tested depends on the nature of her data and what aspects she wants to emphasize. Here’s a brief overview of when to use each type:

1. **Stem and Leaf Plot:** Useful for displaying the distribution of numerical data while retaining the original data values. Best for small data sets.

2. **Bar Graph:** Ideal for comparing quantities of different categories. It is useful if Linda has categorical data or she wants to compare the results of the trials straightforwardly.

3. **Line Graph:** Best suited for showing trends over time or continuous data. This would be a good choice if Linda's trials are measured over a time frame or if she wishes to show changes across the trials.

4. **Pie Graph:** Good for displaying how a whole is divided into its components, though not ideal for comparing multiple trials unless she is comparing parts of a whole.

**Recommendation:** If Linda is comparing results from three trials and she wants to emphasize differences among those trials, a **bar graph** would be the most effective choice. If the data is about a continuous variable measured over time within those trials, then a **line graph** might be more suitable.

In summary, if the goal is to compare discrete results across the three trials, go with a **bar graph**. If the context involves time or progression, a **line graph** would be best.

How does Dahl create suspense in “The Landlady?” Explain. (pick two different methods)

OR

Which element had the biggest impact on the text in creating suspense? Why? Use two examples from the story.

In Roald Dahl's short story "The Landlady," suspense is effectively created through various literary techniques. Here are two methods he employs:

### 1. **Foreshadowing:**
Dahl uses subtle hints throughout the story to suggest that something is amiss. For example, when Billy arrives at the bed-and-breakfast, he notices the peculiar taxidermy in the lobby, including a stuffed dachshund. The unnaturally pristine condition of the animals foreshadows a sinister undertone, implying that the landlady has an unusual obsession with preservation. This sense of foreboding builds suspense as readers begin to question what has happened to the previous guests and what might happen to Billy.

### 2. **Atmospheric Details:**
The setting contributes heavily to the suspense in "The Landlady." The story unfolds in a seemingly quaint and cozy bed-and-breakfast, but the detailed description of the dimly lit, cold atmosphere creates a sense of unease. For instance, the way the landlady invites Billy in, coupled with her overly friendly demeanor, contrasts sharply with the eerie details surrounding her establishment. This stark dissonance makes readers uneasy and keeps them questioning the landlady's true nature.

### Element with the Biggest Impact
The element that has the biggest impact on creating suspense in the text is **characterization**—particularly the portrayal of the landlady herself.

**Example 1:** The landlady is described as overly accommodating and charming, which at first seems welcoming. However, as the story progresses, her peculiar insights—such as her knowledge of past guests—create an unsettling tension. For instance, when she mentions the two previous guests by name, it raises alarm bells for readers, suggesting that they may not have left the bed-and-breakfast alive.

**Example 2:** The landlady’s interactions with Billy grow increasingly odd, especially when she insists on familiarizing herself with him despite their brief acquaintance. Her insistence on keeping his room at a lower price just adds to the strange dynamic. The reader senses that her kindness is masking something sinister, and this feeling intensifies as the story moves toward its chilling conclusion.

Overall, Dahl's skillful use of foreshadowing, atmospheric details, and rich characterization builds a captivating suspense that engages readers and keeps them on the edge of their seats.
