B. Lysosomes. Please rat my response and have a nice day!
2,200 species, and recovery plans were approved or implemented for invasive species.
I am not entirely sure, but i think it would be the respiratory system because plants produce oxygen after taking in carbon dioxide, and that is similar to the human respiratory system. I am not completely sure though. hope this helps!
Answer:
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.
