<span>A secure food supply depends on all of the following EXCEPT?
Choose one answer.
a. maintaing healthy soil and water
b. increased use of fertilizer
c. safe distribution of food
d. biodiversity

So I'm guessing that's the complete question you're looking to have answered (found it on Google), and my best guess would be C. Since normal soil should be enough to grow food, increasing the amount of fertilizer used could cause the soil to be infertile. Hope that was what you're looking for!</span>

Lady bird [3.3K]

33% is the unknown concentration of the tube.

Explanation:

Concentration of stock of windex = 50%

concentration of bacteria = 500 microliter

nutrient broth = 1000 micro litre +500 microlitre of windex
