How do you determine the growth of microorganisms
Answered By: Gilbert Edwards Date: created: Sep 20 2021
While growth for muticelluar organisms is typically measured in terms of the increase in size of a single organism, microbial growth is measured by the increase in population, either by measuring the increase in cell number or the increase in overall mass.

What types of food do microorganisms need to grow
Answered By: Chase Miller Date: created: Jun 18 2022
There are sufficient nutrients available that promote the growth of microorganisms. Protein-rich foods, such as meat, milk, eggs and fish are most susceptible. Foodborne pathogens require a slightly acidic pH level of 4.6-7.5, while they thrive in conditions with a pH of 6.6-7.5.

GuestQuestion: What Happens When Your Computer Runs Out Of RAM?
So what happens when your computer runs out of memory (RAM)?When your computer runs out of memory, your computer will start to use the hard drive space for "Virtual Memory".The more "Virtual Memory" used, the slower your computer will run.The simple solution to this is to add more RAM. What happens if your RAM is full? If your RAM is full, your computer is slow, and its hard drive light is constantly blinking, your computer is swapping to disk. If this is occurring, it's a clear side that your computer needs more RAM – or that you need to use less memory-hungry programs. Why does my computer keep running out of memory?
