The bare soil surface type affects the amount of runoff because it has
no other stopping mechanism that prevents runoff to happen. Just like in the
use of pesticide, it is
harmful to human agriculture because it contains an antifreezing chemical
(present in transportation vehicles). When the chemical seeps into the soil, it
will create a runoff and can seep into the groundwater causing pollution.

Answer:
DNA is negatively charged. When an electrical current is passed through a gel, the DNA is repelled by the nearby negative current and pushed across the gel towards the positively charged side.
Explanation:
Electrophoresis has become a standard molecular biology technique. This technique is based on the use of a constant-uniform electric field that enables the separation and identification of DNA fragments with different lengths, which form bands in the electrophoresis gel. Electrophoresis can be used to analyze not only DNA, but also RNA and proteins. During electrophoresis, the fragments of DNA that are negatively charged will migrate towards the positively charged electrode, where the duration of this movement will depend on the size of the DNA fragment, as well as of the pore size in the gel.
Answer:
Q:
