You would need data from a large number of people, best from a varied age and gender. For each person you would need pulse rate readings of the person at rest not watching television, watching an unexciting television program and watching an exciting sporting event on television. The pulse rates taken not watching television and watching an unexciting program serve as a control and comparison to eliminate the conjecture that watching any television causes pulse rate to increase. You would also have to be sure that each person is watching a sport that they consider exciting rather than one that you consider exciting, not everyone finds the same things exciting. The larger the body of data you accumulate, the more convincing your argument will be.
Answer:
<em>The correct options are</em>
<em> B) If the sources used are peer reviewed</em>
<em>D) If the writing is based on sound evidence</em>
Explanation:
To check whether a scientific report is valid or not, one must determine whether the results deduced from its experiments were accurate and true or not. If the writing provides sound evidence for its experiments to be true and not biased, then the editor will most likely publish it. A report that is supported by peer reviews will be the best to publish as the data in it will be considered to be more authentic and accurate. Hence, option B and D will be true.

Its B. Biological molecule that stores energy
Mitosis goes in the order of PMAT, or Prophase, Metaphase, Anaphase, and Telophase.
Prophase is when the nuclear envelope breaks down and the chromosomes are visible. Metaphase is when the chromosomes line up in the middle. Anaphase is when the spindle fibers pull the centromeres apart. Telophase is when the chromosomes go to the opposite sides and the nuclear envelope reappears.
