Why is it important to aware properties?Chemical classes can be created using chemical attributes. Additionally, they can be helpful in identifying unidentified chemicals and in separating or purifying them from other substances. Minimizing or removing the factors whose effects we are not accounting for in the experiment. We may quantify the changes caused only by the effects of the variables we are interested in by maintaining them as constants (in your sample question, concentration should be the same, high purity and quality material should be picked to remove the effects of undesired contaminants, etc.).

A specialist is a medical professional who has chosen to focus on one field of medicine, such as an oncologist, who treats only cancer, or a podiatrist, who focuses only on treating foot conditions. What are the advantages of seeing a specialist as opposed to a primary care physician? List at least one circumstance in which you might want to see a specialist, and at least one circumstance in which you might want to see a primary care physician.

Answers

Answer:

Explanation:

The advantages of seeing a specialist is because they mastered in one specific type of health problem and can treat that problem well and efficiently, whilst a primary care is to treat many and they may not be able to 100% deal with the problem you are facing.

A circumstance you want to see a specialist is if you have a bleeding/highly wounded internal organ.

A circumstance you want to see a primary care physician is if you have a broken leg or if you have a fever that won't go away.
