After doing PCR on the same region between two individuals, you notice that each person's DNA yielded pieces of different sizes.
vitfil [10]

Answer:

C. This is an example of VNTRs.

Explanation:

VNTRs are Variable Number Tandem Repeats. These are short sequences of DNA repeated in tandem (that is, the sequences are repeated one next to the other) a certain number of times. Unrelated individuals have a different number of repetitions for a certain region of the DNA, therefore the total length of the fragment is variable among individuals, depending on how many times the short sequence is repeated.

Where is long-wavelength radiation created?
Ivahew [28]

On the earth surface

Explanation:

The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted.

  • The sun releases radiation in form of short-wave.
  • They are usually more energetic and with short wavelength and a high frequency.
  • When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat.
  • Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body.
  • When these radiations enters the earth, they are re-radiated back as long waves with lower energy.
  • Earth is cooler than the sun
  • When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back.
  • When the short waves are absorbed, they lose some of their their energy to the earth surface.
  • The remainder is radiated back as less energetic long waves.
  • The hotter a body is, the more energetic the radiation it releases.
