The current increase of carbon dioxide in the atmosphere is as a result of human activities that began in the late 1700s. This period sparked the beginning of the Industrial Revolution and this is when we began to use fossil fuels. The burning of fossil fuels coupled with widespread global deforestation has led to a rise in CO2. Excess carbon dioxide in the oceans causes it to become more acidic. This acidity will affect marine species with shells like mussels and lobsters. <span />
Answer:
The expectations of the bands will be more on the gels.
Explanation:
One sample provides several sizes and thickness bands in the gel electrophoresis according to the size of fragments that run in it. An individual would expect more bands due to the increase in the number of samples which is 20 samples now.
An increase in the number of samples produces more bands. So one can easily expect more bands from the 20 samples. Scientists would get more bands on the gels.
Thus, the expectations of the bands will be more on the gels.

<span>Farmer Brown might be hesitant to clone his corn because cloning eliminates the ability to sexually reproduce and provide genetic variability. There will be no variability in genes in these clones, because given that they are exact copies of their "parent," they will all be identical, without any difference or variation. This farmer doesn't want that to happen, which is why he is hesitant to take Farmer Green's advice.</span>
