bacteria in food can be killed by many means such as:
a) Pickling. for example food is pickled as bacteria cannot live in very acidic conditions.
b) Boiling. boiling water or liquids can help kill bacteria present in them.
c) Using preservatives can also help
d) Immersing food in salt or sugar solutions is also an other way
IV only
Plate IV will only have the trangenic E Coli hence will have the highest percentage of bacteria that are expected to produce insulin.
Explanation:
The transgenic <em>E. coli </em>will have taken up the plasmid with the insulin and <em>amp</em> genes hence they will be able to survive and grow in amplicilin antibiotic.
In plate IV, the wild type <em>E. coli</em> will be eliminated by the antibiotic (because they do not have the gene for resistance) hence providing no competition for resources, in the agar, with the transgenic <em>E coli</em>. This will ensure optimal growth for the transgenic <em>E coli</em> even, than in plate III, producing highest percentage of insulin.

Reproduction is the function of both living <u>plants</u> and organisms.
<h3>What is reproduction?</h3>
Reproduction can be defined as a biological process through which all living organisms (parents) produce their offspring, especially through mating.
<h3>The types of reproduction</h3>
Basically, there are two (2) main types of reproduction and these include;
Generally, reproduction is one of the main characteristics of a living organism and plants.
