Angela set out to determine how many genes
control the length of people's eyelashes. She
compared the length of eyelashes from 12 different
people. She measured each person's eyelash by
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).

Describe one method to reduce the air pollutants released from a coal burning power plant
Answer:
A method to reduce the air pollutants released from a coal burning power plant is carbon capture.
Explanation:
Carbon Capture: It separates CO2 from emissions sources and recovers it in a concentrated stream. The CO2 can then be injected into the soil underground for permanent storage, or sequestration. Reuse and recycling can also reduce the environmental effects of coal production and use.
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.
Why might scientists be interested in using algae for biofuel production?
Answer:
Algae actively absorb carbon dioxide, and therefore reduce the greenhouse effect. Fuel from microalgae is called third-generation biofuel, and development for its production is currently underway. With sufficient information on the composition of biofuels, researchers can significantly improve production processes.
Explanation:
How is energy produced by respiration stored
Answer:
Explanation:
Cellular respiration converts the chemical energy stored in glucose into chemical energy stored in the ATP molecule. The cells break glucose down into carbon dioxide and water while producing energy that they store in ATP molecules.

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.

Cross a heterozygous axial, hybrid round seed plant with a hybrid axial, heterozygous round seed plant. Only list the phenotypic ratio at the end.
Answer:
The phenotypic ratio is 9:3:3:1
9/16 individuals with axial flowers and rounded fruits, R-A-3/16 individuals with terminal flowers and rounded seeds, R-aa3/16 individuals with axial flowers and wrinkled seeds, rrA-1/16 individuals with terminal flowers and wrinkled seeds, rraaExplanation:
We need to cross a heterozygous axial, hybrid round seed plant with a hybrid axial, heterozygous round seed plant. When referring to a hybrid plant for a trait, we are meaning that the plant is heterozygous for that trait.
Let us assume that round is the dominant trait, codified by a diallelic gene, so
R is the dominant alleler is the recessive alleleLet us also assume that axial is the dominant trait, so
A is the dominant allelea is the recessive alleleCross:

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!

If the carrot population increased, the rabbit population would:
NO LINK ANSWERS
A. increase
B. decrease
C. remain the same
Answer:
The rabbit population would remain the same as the increase in number of carrots doesn't determine / effect the population of rabbits.
Hope my answer helps !
Answer:
i believe the answer is c) remain the same
Explanation:
i say this because food availability wouldn't necessarily cause the population to grow (there would need to be an environmental change for this to happen.)
and the population wouldn't decrease because there would be an abundance of food and since starvation is one of the main causes of population decrease (along with over-crowding.)
good luck :)

In a sample of double stranded dna if 19% of the nitrogenous bases are guanine what percent of the nitrogenous bases are adenine
Answer:
31%
Explanation:
Chargaff's law says the amount of A (adenine) = T (thymine) and G (guanine) = C (cytosine). If
G = 19% then C= 19%
19% + 19% = 38%
100% - 38% = 62%
62% for A and T
Divide by 2 and you get
31%

Answer:
Explanation:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt.
Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

What kind of mutation is this? (2 points)
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.
