Which of the following is an example of bioremediation?
a.
using microorganisms to clean up an oil spill
b.
using bacteria to make yogurt
c.
creating plants that are resistant to bacteria
d.
adding nitrogen-fixing bacteria to the soil before planting crops

a.  using microorganisms to clean up an oil spill

Explanation:

Bioremediation is a process of treatment of a culture, biological medium, soil and water with plants and microorganism so as to remove the contaminants present in them. The plants and microorganism either absorb the contaminants or makes them potentially inactive which leads to decrease in pollution.  

a.  using microorganisms to clean up an oil spill is the correct option because the microorganisms will break up the bonds present in the oils therefore, making the structure unstable, unreactive and harmless to the aquatic species.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
