Retrotransposons are class of transposons that contain long terminal repeats and code for an enzyme that synthesize DNA using an RNA template. It is found in all eukaryotes but absent in prokaryotes. About 42% of human genome is made up of retrotransposons. They are particularly abundant in plants, in maize 49-70% genome is made up of retrotransposons.
Answer:
The SimCell will expand due to net movement of alcohol into the cell
Explanation:
Since the SimCell is only permeable to alcohol and not water, only alcohol can move in and out of the cell. Hence, if a SimCell that contains 20% alcohol and 0% water is placed in a solution containing 40% alcohol and 60% water, there would be a net movement of alcohol from the surrounding solution into the SimCell till equilibrium concentration of alcohol is established between the SimCell and the surrounding solution.
<em>Therefore, the SimCell will expand due to the net movement of alcohol into the cell.</em>
The most plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is that B) tropical regions have more available water and higher levels of solar radiation.
Hope this helped!!
