Studying the folding patterns of protein molecules can help microbiologists better understand cellular processes as well as some

diseases, such as Alzheimer’s, that are caused by proteins that have misfolded. The folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this.
A group of researchers at Stanford University developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. As a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. Which statement best describes the work of these researchers?

The work is not scientific because the data are not processed in one location.
The work is not scientific because the simulations are not reproducible.
The researchers applied creativity to solve a problem in running an experiment.
The researchers used only well-established scientific techniques.

Answer:

I believe that the best answer to the question: Which statement best describes the work of these researchers, would be: The researchers applied creativity to solve a problem in running an experiment.

Explanation:

Scientific experimentation, and testing, can be a pretty difficult thing to do, especially when it comes to certain biological and molecular topics. The unwinding of proteins to discover how they have been folded, and thus understand how this process can originate certain diseases, is very complicated and it would be impossible to carry out in a study. However, if researchers had given in to the difficulties, and immensity of the obstacles, to carry out their experimentation, instead of finding solutions that were scientifically acceptable, and also efficient, then we would have never known this key aspect of molecular biology, that could solve a lot of conditions that are untreatable today. These Stanford researchers did exactly that, use ingenuity, within the scope of what science allows, to pursue their goal by making use of the resources that they did have available, and which permitted the study to be carried out. This is why the answer is the third option.

emmainna [20.7K]

Answer:

<em>The correct option is C) Plants</em>

Explanation:

Option A is false because the cell cannot be an animal cell. This is because an animal cell does not possess a cell wall.

Option B is false because the cell cannot be a bacterial cell. This is because a bacterial cell does not have a nucleus. Their genetic material is dispersed inside the cytoplasm.

Option C is correct because all the organelles, a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes, are present inside the plant cells.

ale4655 [162]

Answer:

The correct answer is: exonuclease activity.

Explanation:

DNA Polymerase is an enzyme of critical importance for the replication of the DNA. DNA needs to be replicated so, when entering Mitosis, each daughter cell can have a copy of the genetic material they need.

DNA Polymerase has an exonuclease activity in which mismatched nucleotides are removed from the newly replicated DNA strand in order to prevent mutations that can lead to malfunctioning or harmful proteins.

___ 1. When the combined effect of two drugs, each producing the same biological response by the same mechanism of action, is eq
Valentin [98]

Answer:

Additive effects

Explanation:

In pharmacology, sometimes more than one drug is used to treat a disorder. The two or more drugs are used as they treat the disease more effectively than they treat the disorder independently.  The two drugs interact in one of the two ways: the additive effect and the synergistic effect.

In the given question, the drugs when combined produce the sum of the drugs equal to the effect shown by the drugs individually therefore the effect of the drug is added. This type of drug interaction is known as the additive effect.

Thus, Additive effect is the correct answer.

Nonrandom mating tends to _______ the frequencies of ______ genotypes. increase; homozygous decrease; homozygous increase; heter
Solnce55 [7]
<span>The answer depends of the kind of non-randommating. If the non-random mating is the kind of positive assortative mating then it tends to increase the frequencies of homozygous genotypes. Positive assortative mating when individuals mate with other individuals like themselves. If the non-random mating is the kind of negative assortative mating, then the effect is the opposite as of the positive assortative mating, this is it tends to decrease the homozygous genotypes.</span>

Methodology for Studying Evolution:
Over [174]
The fossil record is important for evolution because they show that life from the past is different from life today. Scientists, such as paleontologists can determine the age of fossils by using technology provided today; known as radiometric dating, to sort them and determine relationships with organisms today. It allows us to get a whole view on the possible relations of today.

Homologous Anatomical Structures provide such a big support to the thought of evolution as well. They are structures that are similar in some organisms because they were inherited from a common ancestor. The functions may or may not have been used by the past ancestors, either. This supports evolution widely due to us seeing what we've evolved from, and what animals have evolved from. It allows us to determine ancestors as well. 

Embryology is a very good one, looking at the early stages of animal development. This allows scientists learn about how different species have evolved over time. It supports evolution largely due to this. A very good branch of science, spreading the thought of evolution each and everyday.

Apologies- I don't have an answer for the other explanations.
