Here's the excerpt.
Guppies are small, tropical freshwater fish that display wide variation in coloration. Some have bright splotches of blue, red, and orange, while others are quite drab and dull. Research has shown that females prefer to mate with brightly colored males; however, this trait makes them more likely to be seen. Guppies, like all species, must be able to both sur<span>vive and reproduce in order to avoid extinction
One process that is responsible for the variations in coloration observed in guppies is that how females mate with male guppies. They prefer to mate with brightly colored males.</span>
I think this is false, but I’m not 100% sure.
Passive transport does not use atp (energy) while active transport does. they both are used to transport molecules were there are needed.
Answer:
In this lab, a visual representation of the process of DNA<em> profiling </em>was created by the process of <em>gel electrophoresis. </em>This process begins by using a restriction enzyme to <em>cut</em> the DNA into smaller fragments. The DNA fragments are placed in the holes of gel called <em>wells</em>. The gel is placed near the <em>negative electrode</em>. The DNA fragments travel toward the<em> positive</em> electrode because the DNA fragments are attracted to that side. The <em>small </em>molecules moved quickly through the gel and the<em> large</em> molecules moved slowly, creating a pattern of <em>bands</em> that can by analyzed.
Explanation:
DNA profiling can be described as a forensic technique which is using for comparing the DNA of different suspects with the DNA found at the crime site.
Gel electrophoresis can be described as a process through which different samples of DNA are separated based on their size and charge to mass ratio. The fragments of the DNA run on an agarose gel where they run from the negative terminal to the positive terminal depending on their size. The smaller molecules having a smaller mass will move faster than the larger molecules.
