Answer:
The moths were typically white with black speckles, which helped them blend in. There was a mutation that caused some of them to be almost entirely black, which would make them easier to spot and get eaten. However, one event that left the trees covered in ash and soot was an advantage for these moths. They blended into the trees more so than the other ones, and there was a giant fluctuation of them. The mutated ones now had a better chance of staying camofluaged, and the white and black speckled ones were more likely to get eaten.
Explanation:
The most obvious reason why scientists sill refer to viruses as being non-living would be the fact that D. Viruses are not composed of 1 or more cells. Since all living beings of life, from the early archae to the complex multi cellular mammalian organism everything is composed of these basic units of life.
We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
