Answer:
a. A natural geological challenge that exists in my environment is a fault zone known as the San Andreas Fault. It's a major geological landmark where two tectonic plates meet in California. People in my area are prepared for the event of an earthquake by packing emergency clothes, food, water, shelter, etc. in the event of a major earthquake. Scientists believe that California is past due for a major earthquake in the 6.0-8.0 range that could happen any day now. Hope this helps :)
Explanation:
The answer is length.
A gel electrophoresis is used for separation of DNA or its fragments on the basis of differences in their length. An electric current is running through the gel with positive pole on the bottom. Because of the difference in the lengths of DNA fragments, some <span>of them </span>will travel more quickly than other. It is expected to see smaller DNA fragments at the bottom of the gel and larger DNA fragments near to the top of the gel.
<h2>Answer:</h2>
<u>Soil erosion can occur in the area where trees are less</u>
<h2>Explanation:</h2>
As we know that trees have long roots spread into soil to a larger distance. Soil erosion occurs when the soil takes the surface land with it. So if the trees are present there they will keep the soil firm and stop it from sliding. Therefore the erosion can probably occur in the land where there are no trees.
The answer is diffusion
The process of diffusion requires a membrane that has pores to allow for gas and liquids to pass through.
