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.
Answer:
This type of mutation occurs when one or more base pairs are added to the gene sequence.
✔ insertion
This type of mutation occurs when one or more base pairs are removed from the gene sequence.
✔ deletion
This type of mutation occurs when one or more base pairs take the place of other base pairs in the gene sequence.
✔ substitution

Give two reasons why photosynthesis in plants slows down then stops during the fall then winter.
Answer: In the winter and fall there is less sunlight and there is less rain
There is a decline in photosynthesis after the sun sets in the winter and fall seasons. There is a decline of the enzymes in the plants that are responsible for the biochemical reaction.
These don't tend to work so so well during the winter cold winds blowing slows down the plant respiration process and hence the less photosynthesis to for the plants. Hence few sugars are not turned into metabolism.Learn more about why photosynthesis in plants slows down.

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?
Answer:
Explanation:
The choices provided are:
a.restaurants that use C-8-coated cookware
b.cookware manufacturers who make pans out of steel only
c.stores that sell C-8 nonstick cookware
d.individuals who use steel cookware at home
From these choices B is the correct answer.
Restaurants that use C-8 cookware will not profit from using it but will need to lose money by replacing the old C-8 coated cookware.
Stores that sell this nonstick cookware will also need to replace their inventory so they won't be making extra money, only losing it.
And individuals at home will still be using steel cookware and won't benefit or lose anything by this change with the regulations of the c-8 coated nonstick cookware.

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.

Sally conducts an experiment measuring plant growth. She finds that after two weeks, a plant that receives water grew 4 cm, but the plant that received soda died. What is the term for what is being measured?
Answer:
The correct answer is - the dependent variable.
Explanation:
In any study or research, the variable is that measured or affected by the change occurs lace in an experiment is called the dependent variable. The dependent variable depends on the factors or the variables that are changed in the experiment.
In this particular study, the variable which is measure is the height or growth of the plant which depends on the change in the hydrating supply so the dependent variable will be - the growth of the plant.

A student experiments with two solutions containing the same solute concentrations
in a beaker that is divided by a semipermeable membrane, as shown.
In which direction will the water move so that the concentrations of the solutions
remain constant on both sides of the membrane?
A in both directions at different rates
B in both directions at the same rates
C toward the right side of the beaker
D toward the left side of the beaker
Answer:
B in both directions at the same rates
Explanation:
Solutions with the same amount of solute concentration is referred to as ISOTONIC. In an isotonic solution, there is NO net movement of water molecules because there is no osmotic gradient i.e. difference in solute concentrations.
In this case, a student experiments with two solutions containing the SAME SOLUTE CONCENTRATIONS in a beaker that is divided by a semipermeable membrane. Due to the equal amount of solute concentrations in both solutions, water moves into and out each membrane at an equal rate.
In order for the concentrations of the solutions to remain constant on both sides of the membrane, WATER MUST MOVE IN BOTH DIRECTIONS AT THE SAME RATE.

*****!!!! lots of points and brainliest!!!******** how do i find the codon and anti codon? :)
Answer:
The way to find a codon is by arranging the sequence of nitrogenous bases of the mRNA in groups of three, the triplets. Once the codon is found, the anticodon corresponds to a complementary triplet to that codon.
Explanation:
Codon corresponds to a triplet of mRNA nitrogen bases encoding an amino acid. Anticodon is responsible for carrying amino acids to the ribosome, according to the information of the mRNA, and the sequence of its triple must be complementary to that of the codon mRNA.
If, for example, a codon of the mRNA is AUG, its anticodon of the tRNA must be UAC, that is, complementary. Then, for the indicated exercises:
