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?

Answers

Answer 1

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

B. Cells cannot process energy.
C. Cells cannot remove wastes.
D. Cells cannot absorb food.
E. Cells cannot make proteins.

Answers

Answer: Option A is the correct option.

Cell cannot divide.

Explanation:

Cell cannot divide if centriole is impaired because centriole is cylindrical tube like organelle that is found in eukaryotic cells and it is made up of microtubules and this centrioles help in cell division by cause the chromosomes to separate. They are located close to the nucleus and help in cell division. Therefore, if the centriole is impaired, it will not be able to facilitate cell division since it's ability to to form spindle fiber which separate chromosomes .

The clade of organisms characterized as containing many extremophilic microbes is archea. The correct option is A.

What are archaea?

A class of microbes known as archaea is related to yet evolutionary separate from bacteria. Numerous archaea have been discovered to survive in harsh conditions, such as high pressures, salt concentrations, or temperatures.

Extremophiles are the name given to these kinds of creatures. Single-celled microbes called archaea have a similar structure to bacteria. They make up the third domain of life and are unique from bacteria and eukaryotes in terms of evolution. Archaea are obligate anaerobes that exist in low-oxygen settings (e.g., water, soil).

Therefore, the correct option is A, archaea regarding the extremophile microbes.

is B?​

Answers

Answer:

9

Explanation:

Another way to represent this question is:

+ AB BA1A2

In the one's column, B and A add to produce a number with a two in the one's place. In the ten's column, we can see that a one must carry in order to get a digit in the hundred's place. Together, we can combine these deductions to see that the sum of A and B must be twelve (a one in the ten's place and a two in the one's place).

In the one's column: B+A=12

The one carries to the ten's column.

In the ten's column: (1)+A+B=(1)+12=13

The three goes into the answer and the one carries to the hundred's place. The final answer is 132. From this, we can see that A=3 because 1A2=132.

Using this information, we can solve for B.

A+B=12 and A=3

3+B=12

B=9

What environmental stimulus is most likely to result in a more rapid heartbeat in an animal?

Answers

Answer:

This question is incomplete, the options are:

A) Decreased temperature

B) Strong southerly winds

C) Presence of a predator

D) Lack of water

The answer is C

Explanation:

A stimulus is something that provokes a response or reaction in a living organism. It can either be internal or external. An animal can respond to stimulus such as hunger, heat, predator etc.

However, among all the listed stimuli in the options, the PRESENCE OF A PREDATOR is most likely to result in a more rapid heartbeat in an animal. This is because the predator stimulus will require the animal to respond by running in order to survive. Running will increase its metabolic activity and cause its heartbeat to increase.

1. Unlike animal cells, plant cells contain A. a nucleus B. chloroplasts c. mitochondria​

Answers

Answer:

Chloroplasts

Explanation:

Chloroplasts makes photosynthesis

Nucleus stores the DNA

Mitochondria produces energy

Unlike animal cells,  Plant cells contain chloroplasts. Option B is correct.



Unlike animal cells, plant cells contain chloroplasts. Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They contain a green pigment called chlorophyll, which captures sunlight and converts it into energy for the cell. This process allows plants to produce their own food.

Animal cells, on the other hand, do not contain chloroplasts. Instead, animal cells obtain energy through other organelles called mitochondria. Mitochondria are often referred to as the "powerhouses" of the cell because they generate energy in the form of ATP through cellular respiration.

So, while both animal and plant cells contain a nucleus and mitochondria, only plant cells contain chloroplasts. option B is correct.

Summarize the roles of glycolysis, citric acid cycle, and the electron transport chain in energy generation. (in 2-3 sentences please) :)

Answers

Answer:

Glycolysis is a series of reactions that take place in the cell cytoplasm. It involves the oxidation of glucose into pyruvate (a 3 carbon compound), that produces (overall)ATP and reduced NAD: an enzyme that carries hydrogen. The number of carbons in each of these compounds is indicated in the green circle.

The carriers FAD and NAD bring the hydrogen and it separates to H+ and electrons (e-). The electrons pass from carrier to carrier and loose energy. This is used to synthesize ATP.

However, there are a lot of hydrogen ions, that unless they are removed, they'll cause a large increase in pH. Therefore, oxygen reacts with the ions to remove it and produce water. This is what the oxygen you inhale is used for (in terms of respiration).

Eukaryotes are those organism which have the DNA inside the nucleus surrounded by the nuclear membrane. They have all the membrane bound organelles and they have complex cell.

_____________________________________RNA TRANSCRIPTION:

Transcription is the first step of gene expression (process by which the instructions in our DNA are converted into a functional product, such as a protein), in which a particular segment of DNA is replicated into a messenger RNA (mRNA) by using the RNA Polymerase as an enzyme. So the information that was in that segment of DNA is now transferred or copied into the mRNA. Both DNA and RNA are the nucleic acids, and the nucleic acids use the nucleotides as its base.

RNA TRANSLATION:

When mRNA is formed, it moves out from the nucleus and attaches it self to the ribosomes. The ribosome is the main hub for the protein synthesis thus called protein factory. The ribosomes have two types of RNA, Transfer RNA (tRNA) and Ribosomal RNA (rRNA).

mRNA basically works as a INSTRUCTOR and tell the ribosome what kind of protein is supposed to be made.

tRNA works as a little boy who does all the errands so it does the grocery for the making of that PROTEIN. The grocery basically include the amino acids which are present in the cytoplasm, and the list for what amino acids are needed is given by mRNA (THE INSTRUCTOR).

rRNA works as a cook, it makes the PROTEIN. It forms the major part of the ribosomal subunits.

After the hard work of the rRNA and all the other types of RNA. THE PROTEIN IS FORMED.

Typically, its an offhand response from a parent to a child when someone has said something that hurt the childs feelings. After all, as long as theres no physical damage, then everything must be fine, right? Hurtful words are often treated as inconsequential. People assume they can be easily brushed aside and smoothed over with a flimsy apology on the part of the perpetrator. But the truth is, words can hurt in more ways than one and the effects often far outweigh any scrape or bruise. In todays world, our stories are no longer limited to simple word-of-mouth tales or even hard-bound books. Words are digital and far-reaching, passed around on websites, on social media, and in text messages. More often than not, the words we publish online are not really for the benefit of others, but for ourselves. Writer Gracy Olmstead says, in the world of internet and social media, another narrative has begun to reign supreme: namely, the self-narration. So, what happens when the words we use become more about self-gratification than genuinely helping or communicating with others? The result can be anything from shameless selfies to cyberbullying, and the effects are tangible. The Texas Education Code defines bullying as an act that exploits an imbalance of power and involves written or verbal expression. This has recently expanded to include digital forms of communication. These include sending vicious text messages, emails or instant messages, and spreading rumors or gossip by posting it to social networking sites. The sneaky thing about cyberbullying is that because its not physical, we underestimate its negative effects. With the anonymity and distance the internet provides, cyberbullies dont have to face the consequences of their actions, and often feel free to say whatever they want about others. History has proven that words can be just as potent weapons as if not more so than sticks and stones. During World War II, the Nazi regime employed propaganda to impress upon German civilians and soldiers that the Jews were not only subhuman but also dangerous enemies. The words of the German government became the defining narrative of an entire group of people. While this false propaganda seems a far cry from the problems facing teenagers today, they all demonstrate the impact of words. Novelist Chimamanda Ngozi Adichie put it simply when she said that the stories we tell are often about power. Power is the ability not just to tell the story of another person, but to make it the definitive story of that person, Adichie said. Perhaps the answer is not to fight to be heard, but rather to learn to listen. When we are empowered to tell our own stories or share our own points of view, our words can have positive, transformative effects. They can help people understand other experiences and see the world differently. Now that youve read about the effects words can have, what do you think? Has anyone ever said something about you that was hurtful or untrue? What did you do about it? How have you used words to solve a problem, bring people together, or share your own story? Why do words matter?
