Food-service equipment should be carefully cleaned and sanitized, in order to prevent foodborne illnesses. Cleaning is the process of removing traces of food from surfaces while sanitizing is the process of removing microorganisms from surfaces. In general, food-contact equipment should be cleaned and sanitized after each use of the equipment. However, when the food-contact equipment is in constant use, it should be cleaned and sanitized every four hours.
Food moves through the digestive system tract by peristalsis, which is produced by wavelike contractions of INVOLUNTARY muscles

Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.
Explanation:
Epistasis is a type of gene interaction in which one gene masks or modifies the expression of another gene at a distinct locus.
Dominance refers to the gene interaction in which one allele of a given gene masks the expression of another alllele of same gene.
The comparison of dominance and epistasis give the following information:
- Dominance involves allelic suppression while epistasis involves non-allelic suppression.
- Dominance involves a single pair of alleles while epistasis involves two pairs of allele.
- In dominance, the expression of recessive allele is suppressed while in epistasis, either recessive or dominant non allele is suppressed.
- The effect of dominance is due to the dominant allele while epistasis may be due to dominant or recessive allele.
