Explain why the absence of bacteria in the food does not necessarily mean the food is safe to eat.
svlad2 [7]

Even if the bacteria is absent from the food, several fungi, mycotoxins, protozoa me be present in the food.

  • Foods are rarely sterile and often contain natural chemical substances. They contain a diverse population of microbes that come from many sources of the natural micro flora.
  • From the time of harvest to the time of preparation and consumption, microbes contaminate the food.
  • A food's microflora is primarily influenced by the type of microbe, the features of the food, contamination, and the conditions during preparation and storage.
  • Foods may contain bacteria, fungus, protozoa, algae, viruses, and other microbial species.
  • The absence of bacteria does not guarantee that the food is safe to consume because there may still be enterotoxins, mycotoxins, fungi, and other difficult-to-identify microorganisms present.

Gene cloning can involve inserting genes into
melomori [17]


The best answer is C.

Gene cloning can involve inserting genes into a plant.

Gene cloning is the deliberate addition of a foreign gene to the genome of an organism. A gen holds the information that will give the organism a trait. 

Genetic engineering removes the DNA from one organism and transfers the gene or genes for one or more traits into another. Since  in this process crossing is not necessary, the "sexual" barrier between species is overcome. Therefore traits from any living organism can be transferred into a plant.
