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.

Answer:
Details about DNA are given in the explanation section. Hope it will be helpful for you. 
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA). 
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.
DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule.  A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. 
A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. 
 
        
             
        
        
        
Explanation:
Botanically, mosses are non-vascular plants
 
        
             
        
        
        
Examples of active transport include the uptake of glucose in the intestines in humans and the uptake of mineral ions into root hair cells of plants.
        
             
        
        
        
You can conclude that the father was either heterozygous for that trait or fully homozygous.
