Biological contaminants in form of different types of bacteria, viruses and other parasites are the biggest cause of food borne illnesses. Food borne illnesses occur by consuming foods that have been contaminated by these microorganisms. Common symptoms of food borne illnesses are: vomiting, diarrhea, abdominal cramps, nausea, fever, etc. Incubation period of these biological contaminants can range from few hours to one week. <span />
The contents of the cell, or the structures of the cell, allow the cell to be "specialized." Together with the cell's proteins, they allow the cell to do specific things. They allow a cell to act like a neuron or a bone cell or a skin cell.

The question is incomplete as it does not have the options which are:
1.a pea plant with all purple flowers and a pea plant with all white flowers produce a pea plant with all purple flowers
.
2.a black sheep and a white sheep produce a gray lamb;
3.a mother with straight hair and a father with curly hair have a son with wavy hair
4. a mother with type A blood and a father with type B blood have a daughter with type AB blood;
5.a green fish and a yellow fish have mottled green and yellow offspring
Explanation:
Complete dominance: A condition in which one of the two alleles shows its complete effect in the form of phenotype in a generation, therefore, the example of a cross between purple and white flower is considered complete dominance as purple colour is produced in a generation.
Incomplete dominance: An event in which both the alleles in an organism do not show their complete effect and a new variant of the phenotype is produced therefore the wavy hair is a new variant of the hair and similarly, grey coloured lamb also are considered the example of incomplete dominance.
Co-dominance: a genetic event in which both the alleles in an organism produces their equal effect on the phenotype and therefore the blood group and the mottled green offspring examples are considered the examples of co-dominance.
