Bacteria that have
taken up the plasmid with antibiotic resistance
gene will grow in a medium laced with the particular antibiotic of interest. More
so, the bacteria that take up plasmid with the lac Z gene, when grown in a medium of lactose only, will propagate. These experiments
are used with selective media that only allows the bacteria with a particular characteristic
to grow.
The answer is true, since catabolism is the breakdown of more complex compounds into more simpler ones.
Well this is simple if just mutiply 10x4 and get 40x. hope this helped.
