please help me i need to know how many amino acids are different and what kind of mutation each mutated dna sequence is
Answers
Base substitutions, deletions, and insertions are the three forms of DNA mutations.
Define mutation.
A mutation is a change in the sequence of genes. Mutations can be as simple as replacing a single DNA building block, or nucleotide base, with another nucleotide base. Larger mutations, on the other hand, can influence multiple genes on a chromosome. A point mutation occurs when one base in the DNA is changed to another. A missense mutation arises when that point mutation results in the placement of a different amino acid from that codon. Due to the fact that numerous codons code for the same amino acid, not all point mutations result in a missense mutation.

During an evening hike, you see a shooting star just like the one pictured here.
In which layer of the atmosphere does this shooting star occur?
troposphere
stratosphere
mesosphere
thermosphere
Answers
The shooting star occurs in the mesosphere, which is the layer of the atmosphere above the stratosphere and below the thermosphere.
The shooting star observed during an evening hike occurs in the mesosphere. Shooting stars, also known as meteors, are visible when small particles, typically from comets or asteroids, enter the Earth's atmosphere and burn up due to friction with the air molecules. The mesosphere is the third layer of the Earth's atmosphere, located above the stratosphere and below the thermosphere. It extends from about 50 to 85 kilometers (31 to 53 miles) above the Earth's surface. In the mesosphere, the air is thin and the temperature decreases with altitude. This layer is where most meteors burn up and produce the phenomenon of shooting stars that we observe from the ground.For more such questions on Mesosphere:

The students performed a new experiment to measure carbon dioxide. Flask one had water only. Last two had eludes only. Flask three had snail only. All three flasks were wrapped in foil and placed in dark. At the beginning of experiment no carbon dioxide was detected. Which test tubes will have carbon dioxide after 12 hours:
Eldoea only
Snail only
Both Eldoea and snail
Answers
Both the flask with Elodea only and the flask with snail only are expected to have carbon dioxide after 12 hours.
Based on the information provided, it is likely that both the flask with Elodea only and the flask with snail only will have carbon dioxide after 12 hours. Here's the explanation:
Flask one had water only, so it does not have a living organism that can produce carbon dioxide through respiration or photosynthesis. Therefore, it is unlikely to have any detectable carbon dioxide after 12 hours.
Flask two had Elodea only, which is a plant. Plants undergo photosynthesis, a process in which they take in carbon dioxide from the environment and release oxygen.
In the absence of light (as indicated by being wrapped in foil and placed in the dark), photosynthesis does not occur, but respiration continues. During respiration, plants release carbon dioxide as a byproduct. Therefore, flask two with Elodea only is likely to have carbon dioxide after 12 hours.
Flask three had a snail only. Snails are living organisms that undergo respiration and produce carbon dioxide as a byproduct. Even in the dark, snails continue to respire and release carbon dioxide. Therefore, flask three with snail only is also likely to have carbon dioxide after 12 hours.
In conclusion, both the flask with Elodea only and the flask with snail only are expected to have carbon dioxide after 12 hours.

John had a science fair project that he needed to do. He wanted to test the effects that organic and chemical fertilizers had on plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.

| 10 | 0.2 | 5.2 | 3.8 |
Part 2: [Insert a line graph representing the height of each plant over the ten days. Title the graph "Plant Growth Over 10 Days."]
Conclusion:
The analysis of the data shows that the chemical fertilizer worked best, as the plant treated with chemical fertilizer grew to 5.2 cm in height, while the organic fertilizer plant grew to 3.8 cm. The plant with no fertilizer did not grow well, only reaching 0.2 cm in height over the ten days.
John's hypothesis that the organic fertilizer would make the plants grow taller was incorrect. The chemical fertilizer had a greater impact on plant growth than the organic fertilizer. To further test this investigation, John could use a wider variety of plants, different types or concentrations of fertilizers, or extend the duration of the experiment.
Questions:
1. A scientific experiment is reliable when it is:
- **Replicable**: The experiment can be reproduced by other researchers with the same results.
- **Controlled**: Variables are carefully controlled to reduce the impact of external factors on the experiment's outcome.
- **Valid**: The experiment measures what it is intended to measure, and the results accurately reflect the effect of the variables being tested.
2. Using peer-reviewed evidence during a scientific investigation is crucial because:
- It ensures the information is accurate and reliable, as it has been reviewed and approved by experts in the field.
- It helps maintain high standards of research and reduces the likelihood of using incorrect or misleading information.
- It promotes the sharing of knowledge among researchers and encourages collaboration, which can lead to more reliable and effective scientific investigations.
Conclusion Questions:
John's hypothesis was incorrect because the data showed that the chemical fertilizer made the plants grow taller than the organic fertilizer.
Based on the data in the table, the chemical fertilizer worked the best, as it led to the greatest increase in plant height (5.2 cm) after ten days.
The plant that did not grow well was the one with no fertilizer, as it only reached 0.2 cm in height after ten days.
Analysis Questions:
To improve this experiment, John could:
- Test different types or concentrations of fertilizers to see how they affect plant growth.
- Use a larger sample size of plants for each fertilizer type to account for any variability within each group.
- Extend the duration of the experiment to observe the long-term effects of the fertilizers on plant growth.
This experiment can be beneficial in real-world applications by helping farmers, gardeners, and agricultural companies determine which type of fertilizer is most effective for promoting plant growth. By understanding the impact of chemical and organic fertilizers on plant growth, they can make informed decisions about the best fertilization practices for their crops and gardens.

Regarding David's responsibility for his crime, it is difficult to say. The prosecution argued that he had lost his temper and murdered the client in a fit of rage, but there may be other factors at play, such as mental illness or diminished capacity.
The fact that David was reported to be acting "out of character" in the days leading up to the murder is significant, as it suggests that there may be underlying issues that contributed to his behavior. However, it is important to note that this alone does not absolve him of responsibility for his actions.
In conclusion, David's case highlights the complex nature of criminal behavior and the many factors that can contribute to it. While it is important to hold individuals accountable for their actions, it is also important to consider the broader context in which those actions occurred.

Comprehensive detail and links between structure and functions of cells and different tissue in animals
Answers
The main diffrence between their tissue is
1.Plant structure is different from the animal skeletal structure. A plant tissue is different from those in animals. Plant tissues are basically divided into two: Meristematic tissue and Permanent tissue.
Meristematic tissue: These tissues comprise of cells which have the dividing capacity. They are immature and help plants to divide continuously throughout the life. Depending on the site of location, it is of three types. Apical, lateral and intercalary meristems. These meristems enlarge the cell and increase the length and width of the stem, roots and leaves.
Permanent tissue: Permanent tissues are derivative of meristematic tissue. They don’t have the dividing capability but aid in other functions like conduction of substances, storage of food etc. Two types of permanent tissues are found in plants i.e. simple and complex permanent tissue. Simple permanent tissues include parenchyma, collenchyma and sclerenchyma while complex tissues are xylem and phloem.
Animal body is made of four different types of tissues.
Epithelial Tissue
Muscle Tissue
Connective Tissue
Nerve Tissue
Epithelial Tissue: All organs in the body are lined with a group of tissues called epithelial tissues. They cover the surface of all internal as well as external organs. There are four types of epithelial tissues: Squamous epithelium, Stratified epithelium, Cuboidal epithelium and Columnar epithelium. They may be cuboidal, columnar or even flat. The main functions of these tissues involve protection, secretion, absorption, sensation etc..
Muscle Tissue: This type of tissue forms three types of muscles, namely skeletal (striated or voluntary) muscle, smooth (unstriated or involuntary) muscle and cardiac (heart) muscle. They help in movement by contraction and relaxation of muscles.
Connective Tissue: As the name suggests, they connect the different tissues, organs and parts of the body. Different types of connective tissues are Areolar tissue, Adipose tissue (fat), Blood, Lymph, Bone and Cartilage. They connect and support organs and also transport substances between organs.
Nervous Tissue: These tissues are made up of specialised cells called nerve cells (neurons). They conduct and transmit electrochemical impulses between neurons.

Answers
The 3-month profit for this investment scenario is a loss of $21.32.
The 3-month profit for this scenario can be calculated as follows:
First, we need to calculate the purchase price, which is the average between the bid price and the ask price. This is $50.27 per share.
Next, we multiply the purchase price by the number of shares to find the total cost of the investment, which is $5027.
Then, we need to subtract the brokerage commission of 0.3%, which is $8.32.
The total cost of the investment after the commission is $5018.68.
After 3 months, we need to add the interest earned on the investment and subtract the dividend of 1 per share.
Finally, we calculate the sale price of the shares, which is the average between the bid price and the ask price, which is $50.4 per share.
The total sales price is $5040.
The 3-month profit is the difference between the sale price and the total cost of the investment, which is $-21.32.
In conclusion, the 3-month profit for this investment scenario is a loss of $21.32.
