Krusty was told that a certain itching powder was the newest best thing on the market; it even claims to cause 50 % longer lasting itches. Interested in this product, he buys the itching powder and compares it to his usual produce. One test subject (A) is sprinkled with the original itching powder, and another test subject (B) is sprinkled with the Experimental itching power. Subject A reported having itches for 30 minutes, Subject B reported to have itches for 10 hours.

Hi, you've asked an incomplete question. The full question reads;

1. Identify the:

2. Explain whether the data supports the advertisement's claims about its product.

Answer:

Explanation:

1. Remember, the Control group in research often refers to the group in a research experiment that who are not subjected to any treatment, rather they are used as a comparison scale to see how other tested subjects perform.

2. Remember, the advertisement of the "certain itching" "claims to cause 50% longer lasting itches". Hence, we can conclude that the data support the advertisement claims since subject B did itch over 50% longer than subject A. In fact, we are subject B itched for 10 hours, not the 30 minutes subjet A itched.

For this assignment, you will first make a model of a DNA strand using pop beads. This DNA strand
codes for a protein, which determines a trait in an organism. Next, you will change the base sequence of
your model in three ways to show how mutations occur. Then, you will compare the base sequence of the
mutated models to sequences on a key provided by your teacher to find out whether the mutated strand
creates a protein that is beneficial, harmful, or neutral. Finally, you will answer some questions to
summarize what you have done in this project. The Student Worksheet on the last few pages of this
document will help you complete your assignment.
Background Information
DNA is the genetic material passed from parent to offspring. It is an important molecule because it carries
instructions used for producing proteins. These proteins determine how an organism looks and functions.
DNA is a double-helix molecule. The two sides of the molecule, its backbone, are made of sugar
molecules and phosphate molecules. These sides are connected by rungs made of nitrogen bases. The
nitrogen bases of DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
A gene is a segment of DNA that codes for a specific trait. The sequence of nitrogen bases in a gene is
copied from DNA into a strand of RNA in the nucleus of a cell. The RNA then moves out of the nucleus to
the ribosome. The ribosome uses the information that RNA copies from DNA to produce proteins that
have specific shapes and functions. The shapes of proteins help them perform their job. If the shape of
the protein is changed, the protein may not be able to perform its function. A mutation, which is a
permanent change in the DNA sequence in a gene, may change the shape of the protein it codes for.
Types of mutations include substitution, insertion, and deletion. The effects of mutations on organisms
may be beneficial, harmful, or neutral.

Cookware companies have been using a chemical called C-8, which helps to create a nonstick coating to pans. However, the Environmental Protection Agency (EPA) recently claimed that the use of C-8 in the manufacturing of nonstick cookware should be discontinued because studies show it causes cancer.

Who might benefit financially the most from the EPA’s claim?

Recovering Ecosystems Worksheet Section 1: Select the Kitakami River region, the Abukuma Highlands, or Japan's coastal habitat as the ecosystem you want to help with recovery. List the main problem faced by this ecosystem as described in the lesson. Then list at least two sub-problems that need to be considered to solve the main problem. List the sub-problems in order of most to least important. In the rationale column, explain why you placed your sub-problems in the order you selected. Main Problem Sub-Problems Rationale Section 2: Conduct internet research on your selected ecosystem to help you generate a list of three criteria and two constraints. Your criteria and constraints should consider relevant factors to the problem, such as costs, reliability, safety (to humans and wildlife), human needs, environmental impact, local biodiversity, and the aesthetics of the area. List the criteria in order of most to least important and assign each to a related sub-problem. In the rationale column, explain why you placed your criteria in the order you selected. Constraints Criteria Rationale Which Sub-Problems does this criteria address? Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem. Sub-Problem Proposed Solutions Rationale Section 4: Answer the following analysis questions about your proposed solutions. Describe the ways your proposed solutions decrease the negative effects of habitat destruction and human activity on your selected ecosystem. Describe the costs, safety, and reliability of your proposed solutions, as well as any social, cultural, and environmental impacts your solutions address. Evaluate your proposed solutions for their impact on overall environmental stability and changes. Which solution has more impact? Explain your reasoning for picking one solution over another. How could you refine one of your proposed solutions to further reduce environmental impact and loss of biodiversity while also addressing human needs?

Which of the following explains why a mountain can become flat after millions of years?

Weathering and erosion cause the soil from the mountain to erode down the mountain's slope.

Heat from the sun causes the soil to dry out, decreasing the mountain's volume and causing it to sink

The mountain crumbles away after losing all its nutrients because there are too many trees
