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
Question 4 of 5 Which phrase best describes an individual organ? O A. Made of one kind of cell B. The simplest unit of life O C. Meets all the needs of an organism O D. Made of different kinds of tissues
The answer is D it's made of different kinds of tissues,due to the fact most animals and plants have organs,which are self-contained groups of tissues(more than one) such as the heart that work together to perform one function.

Your answer:
Answer:
Captive breeding program
Explanation:
A captive breeding program can be defined as the process of collecting wild specimen and allowing them to reproduce in an environment away from predation. This is an important part of saving endangered species. Specimens of such species are bred in zoos and similar facilities in order to build a healthy population. Sometimes, these species are successfully reintroduced back into the wild. Examples of animals that were successfully saved like this are the California condor, black-footed ferret, golden lion tamarin, and red wolf.

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)

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.

Cattle and buffalo share a similar fundamental niche, the entire set of conditions under which a population can survive and reproduce. A realized niche is the set of conditions actually used by a given population. Explain what the data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist. Use evidence to support your explanation.
Answer:
The data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist with evidence is discussed below in detail.
Explanation:
2.
From the graph, it is observed that Cattle and Impala have the most overlay in their nutrition.
3.
When Sorensen's index worth is more like 1, there is a contestant among animals for their food manner needs.
From the Venn diagram, we recognize that Cattle and Impala have the most overlay in their nutrition. Also, Sorensen's index worth = 0.82 (closer to 1 concerning other partners.
4.
Sorensen's index for Buffalo and Cattle is 0.48 (cheapest among these 3 partners). So, they are less competitive. So, they can persist and generate easily.
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.
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.

A small, leafy branch is cut from a tree. After some hours, the stem of the branch remains firm . Suggest an explanation for this
Answer:
Explanation:
When a branch is detached from a tree, water is being lost through the porous open area. After some time, a callous formation of new tissues starts to appear on the open surface to terminate further loss of water. The osmotic pressure in the leaves gets reduced as they no longer contain enough water, while the stem is being filled with water due to the network of capillaries.
