Answer:
B) formulating a strong hypothesis
Answer:
D. WBC count
Explanation:
First, let's define symptom and sign.
A <u>symptom</u> is some sort of evidence that could suggest a disease or disorder, but it must be observed and noticed by the patient. Basically, it's what the patient feels.
So, a headache, pain, and nausea are all symptoms.
A <u>sign </u>is evidence that someone else observes or collects. So, a family member or doctor sees signs.
Therefore, temperature, white blood cell count, and pulse are all signs.
The question asks us which is a sign, not a symptom. Therefore, the best choice is D. WBC count
Hydrogen bonds rely on polar and covalent bonds because the hydrogen will have a very slight positive proton charge because of the negative electrons being pulled more towards the other element. Because of this proton positive charge, the hydrogen will be attracted to other electronegative charges. This is information on a polar covalent bond. This explains why this is really reliable for hydrogen's usage.
