Answer:
The plasmid must express a gene for ampicillin resistance (the protein product of the <em>bla</em> gene codes for beta-lactamase, the protein that breaks down ampicillin). The colonies on the ampicillin plate are antibiotic resistant. This means that they have taken up the transformed plasmids expressing both the <em>bla</em> gene and the GFP gene.
Explanation:
The transformation involved the genetic modification of a plasmid to incorporate the gene encoding the green fluorescent protein (GFP) from jelly fish. GFP makes cells glow under UV light.
In genetic engineering, scientists use antibiotic resistance as markers to indicate cells that have been transformed. By incorporating an antibiotic resistance gene such as <em>bla</em> into the vector (plasmid) and then growing the cells in antibiotic media, scientists determine which colonies have taken up the plasmid. Therefore, if the cells survive, this means that they contain the plasmid with antibiotic resistance gene as well as the GFP gene.

<u>Explanation:</u>
One physical difference between the hands and feet is that the human hands appear to be more flexible than our feet. Also, in terms of size, our feet are smaller than our hands.
Let's assume that our feet become as flexible as our hands and the hands less flexible, it would affect the function they perform.
- If for example, we were to walk with our hands we will fail to achieve stability.
- And if for example, we decide to grab hold of items with our feet we will be unable to do so.
It is also reasonable to expect other primates to have hands and feet that differed from ours because they are necessary so they can adapt to their environment just like humans too.
