for sterilizing a growing medium, use ______.
a. 3 part bleach to 5 parts medium
b. 3 part alcohol to 5 parts medium
c. 1 part bleach to 10 parts medium
d. 1 part alcohol to 10 parts medium

Explanation:

To sterilize a growing medium, bleach is commonly used for such purposes, and the appropriate ratio is typically 1 part bleach to 10 parts medium (option c) as it's a standard dilution for sterilizing growing media, while alcohol is more for surface sterilization of tools or small items rather than bulk growing medium, and the other bleach ratio (3:5) is too concentrated.

Answer:

c. 1 part bleach to 10 parts medium
