Answer:
A white-eyed fly is born into a population of brown-eyed flies.
Explanation:
In the example, a new mutation (i.e., white-eyes) has appeared in the progeny. In the case that this new mutation has adaptive value, it will be transmitted across generations and therefore will increase its frequency in the population
The number of trials completed during the experiment would be the correct answer.
<em>A megaphone used by a cheerleader can allow people on the opposite side of a field to hear her better because;</em>
D. Solid objects can change the direction of sound waves; megaphones allow users to determine the general direction of the sound.
<u>Determination of the general direction of the sound lessens its dispersion and thus, it reaches the observers at a higher intensity, hence it being louder.</u>
A change in DNA could result in a changed sequence by the amount of atoms and chemicals in the DNA
<h2>Gel Electrophoresis</h2>
Explanation:
- Gel electrophoresis is a technique used to separate DNA fragments by size and charge. Electrophoresis consists in applying a current through a gel that contains the molecules of interest. Based on their size and load, the molecules will travel through the gel in different directions or at different speeds, thereby separating each other. All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis separates DNA fragments only by their size
- Electrophoresis allows us to see how many different DNA fragments are present in a sample and how large they are with respect to each other. We can also determine the absolute size of a DNA fragment by examining it next to a standard "scale" of fragments of known size
- They can be conducting such an experiment to find which of the students has which alleles are identified
