A researcher is setting up a randomized clinical trial to evaluate the effect of acetaminophen on liver
function, and designates a control group of subjects and an experimental group of subjects. What could
interfere with the results or completion of this study?
Answer:
Explanation:
Ordinarily, the control group will be the group that has reduced liver function but are provided with placebo while the experimental group will be the group that has reduced liver function and are treated with acetaminophen.
Some factors that could interfere with the results of this trial are
1) Some of the volunteers could have been on some medications before the trial started, that could affect the result of the study because the medications could hamper or improve the liver function or even the performance of the drug (if it is still present in the body system).
2) Some symptomatic volunteers could be using some medications (without the researcher's knowledge) to help alleviate the pain of the reduced liver function. These medications could also affect the result as discussed in the (1) above.
3) Some volunteers could have pre-existing health conditions (that may be known or unknown to them). This could also affect the result of the research as this pre-existing health condition could render the dosage of the drug "ineffective" or even contribute to the deterioration of the liver.
One major factor that could interfere with completion of the study is the availability of patients that will consent to be used as volunteers for clinical trial. Since there are other known/effective drugs for improving liver function, it might be difficult to convince people to consent to this trial thus elongating the completion time of this study
1. If you flipped two coins simultaneously, for a total of 8 times, how many times, on average, would you expect to get two tails?
2. What was the percent deviation of tails when 10000 observations were made?
3. What was the percent deviation for tails when the coin was tossed 10 times? To get the percent deviation for tails, take the number you recorded for deviation, multiply by 100, and divide by the "expected results"
4. In the 10000 coin flips, you completed the "expected" column, and a value was given for the "observed results" column. What was the deviation for heads?

In essence, DNA is a thin and very, very long organic molecule. It is a polymer, and each of the monomers that constitute it are called ______
Answer:
nucleotides
Explanation:
DNAs are long-chain, helical macromolecules that store genetic information They are made up of varying sequences of covalently bonded monomers called nucleotides. Four types of nucleotides make up the nucleic acid DNA, these include Adenine, Guanine, Cytosine and Thymine.
Unlike other macromolecules, these are typically not used as an energy source and only encode protein synthesis. They comprise a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.
Nitrogenous bases encourage base-pair formation through hydrogen bonding. Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.

Which of the following best explains how the cell theory was developed?
Cells are so diverse that scientists had to come up with an explanation that would apply to all types of cells.
Mutations occur and cause changes in cells so scientists could not develop a law that would apply to all forms of cells.

In an old experiment, Jean Baptista van Helmont grew a plant in a pot
that he filled with 200 pounds of soil. After several years, the plant
grew to weigh 169 pounds. The amount of soil in the pot did not
change; it still weighed 200 pounds. Based on your knowledge of
photosynthesis, how did the plant gain most of its weight?
A. The plant gained weight by absorbing nutrients from the soil.
B. The plant gained weight by producing oxygen and storing it.
C. The plant used carbon dioxide to make organic compounds like
glucose, which increased the plant's weight.
D. The plant made carbon dioxide from organic compounds like
glucose, which increased the plant's weight.
Answer:
C. The plant used carbon dioxide to make organic compounds like glucose, which increased the plant's weight.
Explanation:
Plants are mostly autotrophic organisms i.e. have the ability to make their own food via the process of photosynthesis. The food, which s in the form of sugars makes up their biomass. Plants use carbon dioxide (CO2) in the presence of sunlight to make organic compounds such as glucose, which is necessary for growth.
Hence, according to this question, the plant in a pot filled with 200 pounds of soil gained weight and increased to 169 pounds because the plant used carbon dioxide in the process of photosynthesis to make organic compounds like glucose, which increased the plant's weight.
Conjecture what would happen if a primate infant did not possess your chosen primate hand features. Answer this question with the survivability of the infant in mind
Answer:
Where the primate infant did not possess primate hand features, it will not be able to feed itself. For example, a monkey cannot survive without its grasping hands. It uses them to feed itself. So if an infant monkey does not possess the primate hand features, its survival will be greatly hampered.
Explanation:
Ordinarily, primates (including humans) have five fingers on each of their hands and five toes on their feet. Most primate species have fingernails instead of claws, and they have touch-sensitive pads on each of their digits. The hands and feet of all primates are designed for grasping, with the only exceptions being humans. Human beings feature deep perceptions that differentiate them from other primates.

Peduncle
Explanation:
The Caudal Peduncle or Peduncle in this case is the muscular region that is found between the dorsal and an.al fins.
This Peduncle helps the fish to swim and navigate the currents in the water.
It helps to propel the fish to move quickly through water as it acts like a motor.
Duchenne Muscular Dystrophy (DMD) is an X-linked recessive trait that causes muscular weakness, deterioration of muscle tissue, and loss of coordination. The allele for DMD is represented by Xd and the normal allele is represented by XD . Neither parent has DMD, but both of their sons express the trait. What are the genotypes of the parents?
Answer:
The correct answer is - XDXd and XD Y
Explanation:
Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-
in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.
So the correct genotype would be
mother: XDXd ( a carrier woman)
father : XDY (normal man)

How can both of these samples be pure phosphorus?
State your claim. Make sure your claim fully explains how the two samples can both be pure phosphorus. Summarize the evidence you have gathered to support your claim and explain your reasoning.
Answer:
If impurities are removed from the samples, pure phosphorus will be obtained.
Explanation:
Both of these samples be pure phosphorus if the atoms and other impurities are removed from chemical as well as physical means. Pure phosphorus means that there is only atoms of phosphorus present but pure phosphorus is not available because of its reactivity so for that reason it reacted with the oxygen present in the air and formed phosphate molecules and stabilize itself.

Explain how Karen’s science project demonstrates capillary action in the following scenario.
For her science project, Karen brought two clear glasses of water. She put a large, clear straw in one glass. Karen tried to suck up the water in the glass without the straw by hovering over the water and creating suction with her lips, but she did not touch her lips to the water. The water did not suction into her mouth. In the other glass, Karen sucked through the straw, and her audience could see the water was transported from the glass to her lips.
Answer:
Capillary action explained in the following scenario above, because if you picture the roots as the cup, the water as the water, the straw as the channels, and Karen as the plant. As Karen sucked through the straw, it was as the plant was sucking up the water through the channel from the roots. The water transported from the glass to her lips it was an example of the roots holding the water and transporting it to the plants by the channel.
