I believe the answer is limestone..
Preganglionic fibres originate in the sacral region off the spinal cord.
The reaction of bromelain and gelatin dehydration is hydrolysis
<u>Explanation:</u>
Hydolysis is a process where water breaks down one or more chemical bonds. Bromelain a protease(protein digesting enzyme). Gelatin is an animal protein but is a collagen.
These protein are dietary compounds. So, bromelain will digest the animal protein. In other words, protease can be broken down into to polypeptides i.e a polymer,only through the process of hydrolysis. Therefore, bromelain will hydrolyse the peptide bond in gelatin.
The best way to prevent the growth of bacteria on food preparation surfaces is sterilization. Details about sterilization can be found below.
<h3>What is sterilization?</h3>
Sterilization is the process of treating something to kill or inactivate microorganisms.
Sterilization can also be done to prevent the reproduction of microbial population.
It is a known fact that microbes are responsible for food spoilage, hence, to prevent this, it is important to kill or get rid of them.
Therefore, the best way to prevent the growth of bacteria on food preparation surfaces is sterilization.
