placing the eyelash on a metric ruler and measuring
the length directly.
What is a possible source of error in her
experiment?
A. She did not collect data from enough
people.
O B. She should have considered the number of
eyelashes on each eyelid in her data
collection.
O C. She may have had a difficult time making
accurate measurements directly.
O D. She did not include a control group.
The statement 'she did not collect data from enough people' is a source of error in an experiment (Option A).
What is the N sample?The N sample refers to the number of objects and/or persons tested during an experimental procedure.
The N sample is fundamental for eliminating the source of variation that may lead to errors.These errors are a consequence of faulty testing of a suitable number (N) sample.In conclusion, the statement 'she did not collect data from enough people' is a source of error in an experiment (Option A).

How is a warm front different from a cold front?
Warm fronts cause snow flurries in the winter, while cold fronts cause several days of rainy weather.
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.
Warm fronts cause several days of cloudy weather, while cold fronts cause heavy snow in the winter.
Warm fronts cause thunderstorms in the summer, while cold fronts cause rain when the air is humid.
Answer:
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.
Explanation:
i'm pretty sure
Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather. So, the correct option is B.
What are Warm and cold fronts?A warm front forms when a mass of warm air enters a space that previously held cold air. As warm air passes over cooler air, it rises and cools, which can result in the formation of clouds and precipitation. Unlike a cold front, a warm front often brings with it lighter and more widespread precipitation. Warm fronts often bring warm temperatures and high humidity levels.
When a mass of cold air approaches an area that was previously surrounded by warm air, a cold front is formed. When cold air flows into warm air, the warm air is forced to rise rapidly, which can result in thunderstorms and heavy rainfall. More extreme weather changes, such as a sharp drop in temperature and drop in humidity, are often brought about by cold fronts.
So, the correct option is B.

Why are organisms in lower parts of the food chain not affected but organisms at the top of the food chain are?
Answer:
the organisms at the top of the food chain are effected because theyre bigger and the need more food and prey to survive. for example sharks, if fish arent thriving because they arent eating enough from the bottom of the food chain, the sharks cant eat them and the sharks will starve.
Explanation:
Answer:
The organisms at the bottom of the food chain have a tendency of reproducing faster. (unlike the top of the food chain). Don't think that the the organisms at the bottom of the food chain are not as important though! Everything is important in any food chain!

Shawn explains that many studies have shown that directly spraying bees with fungicides doesn't harm them. Are those results consistent with what Shawn has discovered? Explain your answer in a few sentences.
Answer:
Yes.
Explanation:
Yes, the results will be consistent of spraying bees with fungicides because the fungicides affect the growth of fungus not the bees. fungicides are the chemicals kills fungal growth while on the other hand, insecticides will kill the insects such as ants, bees etc. If the Shawn apply insecticide on the bees, it will kill the bees due to its effectiveness so that's why the results of the directly spraying bees with fungicides will always be consistent due to its ineffectiveness.

Answer:
The correct answer is - Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment.
Explanation:
In any scientific knowledge development process, scientists need to follow the scientific process in a particular sequence that helps in developing and testing a hypothesis.
The sequence has:
observation: Observation requires you to pay attention to occurrences around
Forming question: on the basis of observation form a question about why that occurrence happens.
Hypothesis formation: The hypothesis is your initial prediction on why that happens.
Experiment: The experiment is being done in order to collect data and analysis so you can test your hypothesis

d) What is the new mRNA strand formed by this gene? (3 points)
e) What are the new amino acids formed from this gene? (3 points)
f) Describe how the mutation has affected the protein coded by this gene. (3 points)
The mRNA base sequence formed during transcription, using the DNA sequence TAG CAT GGC AT would be: AUC GUA CCG UAG. The first three amino acids in the protein formed from this gene would be: Isoleucine, Valine, and Proline. The new mRNA strand formed by this gene due to the mutation would be: AUC GUU GCC UAU
What are the new amino acids formed from this gene?The new amino acids formed from this gene due to the mutation would be: Isoleucine, Leucine, and Cysteine (since the codons for these amino acids are AUG, CUU, and UGU respectively).
Describe how the mutation has affected the protein coded by this gene.The mutation has affected the protein coded by this gene by changing the second amino acid from valine to leucine. Depending on the specific protein, this could potentially impact its function and structure, which could affect the organism's phenotype.

How does it make you feel about the state of our environment?
Answer: Walking plays an important role in improving our quality of life because it helps protect and improve the living environment and natural resources. ... Communities designed to be walkable have the potential to reduce air pollution and greenhouse gases because people may choose to walk or bike rather than drive.

Explain how cellular respiration is important for the production of ATP build on aerobic vs anaerobic
Answer and Explanation:
ATP is the energy molecule of the organism, being necessary for all cellular processes. It is produced in both aerobic and anaerobic respiration, but the processes are different.
Aerobic respiration, ATP is produced by breaking down the glucose molecule found in the food we consume. This process occurs in all organisms that need the presence of oxygen to survive. However, this is a complex process that occurs with the help of several enzymes and co-enzymes that perform various oxidation reactions on the glucose molecule, transforming it into carbon dioxide, water and ATP.
Anaerobic respiration is also known as fermentation and occurs in all organisms that cannot survive in the presence of oxygen. This process also occurs with the help of enzymes and coezimas, where the glucose molecule is degraded until it becomes two molecules of pyruvate. During the pyruvate degradation reactions, an ADP molecule is released, which will later be added to a phosphate molecule that is free in the cytosol, becoming ATP.

Why do cells need to undergo meiosis
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
