When conducting scientific research, appropriate methods must be used to find information that is reliable and valid. Angela was assigned a research project about human body systems for her anatomy course. She would like to focus on the immune system, and more specifically, the effects of HIV on the immune system. Which of the following options would be the best way for her to conduct an online search about her topic?A. Type in human body systems + HIV. B. Type in immune system + human. C. Type in HIV immune system. D. Type in human immune system + HIV effects.

D. Type in human immune system + HIV effects.

Explanation:

Since Angela is focusing more on the human immune system and the effects of HIV could have on it, the keywords combination that would produce the most relevant search result has to contain human, immune system and HIV effects.

Option A has human, body systems and HIV, immune is absent.

Option B contains immune system and human, no HIV effects.

Option C contains HIV and immune system, no human.

All the options are lacking in some ways and will not produce the most relevant search results.

The correct option is D. It has all the necessary keywords.

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
