Answer:
Both physical and chemical factors
Explanation:
A mutation is any alteration in the DNA sequence of the genome of a particular cell/organism. Depending on the type and localization, a mutation can be neutral, deleterious, or even beneficial for the individual that possesses it. Moreover, the mutation rate refers to the probability for a mutation to appear in a cell/organism. Exposure to physical environmental factors (e.g. ultraviolet radiation, X-rays, gamma rays, etc) and chemical factors (e.g., bromine) can increase this likelihood.
<span>What MUST occur before mitosis and meiosis can occur is B) DNA replication. DNA replication is a process of copying DNA into an identical copy. Before mitosis, the genetic material of the mother cell must duplicate so that each daughter cell have the same amount as the mother cell. On the other hand, meiosis is a reductive division. But meiosis II is similar to mitosis, so DNA replication is also necessary.</span>
Answer:
A double blind experiment
Explanation:
A double-blind experiment refers to an experiment in which the information about the treatment of the studied variable is provided to neither the researcher nor the participant. In this type of experiment, both the participant and the experimenter are unaware that which participant has got the experimental treatment.
This test is used by the drug researcher in which the placebo treatment along with experimental treatment is provided. This experiment is performed to ensure that the results are unbiased and the chances of errors and prediction get reduced.
Thus, A double-blind experiment is correct.
Reviewing of articles summarizes the current state of understanding on a topic within a certain discipline.
<h3>What is an article review?</h3>
This is a type of professional paper writing which demands a high level of in-depth analysis and a well-structured presentation of arguments and a critical evaluation of literature in a particular field through summary, classification, analysis, and comparison.
<h3>Introducing the main idea of an article:</h3>
The first sentence should explain the subject being discussed in the passage.
A signal phrase is a short introductory phrase that indicates that a quote or paraphrase is coming. To introduce a signal phrase, you provide an effective transition between your own ideas and the evidence used to explore your ideas.
To include a quote, use the author's last name and the page number from which the quotation or paraphrase is taken.
To include a sentence which discusses the quote chosen, you:
- Use a full sentence followed by a colon to introduce a quotation.
- Begin a sentence with your own words, then complete it with quoted words.
- Use an introductory phrase naming the source, followed by a comma to quote a critic or researcher.
Hence, a review article is generally considered a secondary source since it may analyze and discuss the method and conclusions in previously published studies.
