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.

Answer:
Hypothesis: If the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time. The data of this lab supported the hypothesis because there was a difference in bird when fruit was removed
Explanation:
Answer:
depolarization leading to action potentials
Explanation:
The voltage-gated Na+ channels are responsible for rapid depolarization phase of the action potential. Action potential generation require depolarization of neuronal membrane which is acquired by influx of sodium ions through voltage gated sodium ion channels. If the Na+ channels are blocked, there will be no influx of sodium ions to cause depolarization hence action potential will not be generated.
