How can gel electrophoresis be used to help illegal poaching of great white sharks?
statuscvo [17]

Explanation:

Gel electrophoresis is one simple and cheap laboratory technique used in profiling. In this case, it can be used to identify Great White Sharks using their proteins or DNA. This way, even if the fish is completely mutilated into the meat, the species can still be identified helping policies to be enforced.

DNA or proteins of a sample of suspected meat is processed and passed through gel electrophoresis. The bands that form are then compared with a standard to check if the bands match. A match indicates that the meat is from a Great White Shark.

wind energy gaining support as a possible energy source for people. what is the source of the energy that generated wind?
Ivahew [28]

<u>Answer</u>: The energy source that generates wind is actually the sun.

<u>Explanation</u>: The uneven heating of the Earth's surface by the sun gives rise to differences in atmospheric pressure. Areas such as deserts will warm the air masses above much more. As air is heated, it has a lower density as it expands and thus will form a point of low atmospheric pressure. The opposite situation applies for high pressure areas.The air movement from areas of high pressure to areas of lower pressure is what we call wind.
