Answer: a) If the independent variable is changed, then the dependent variable will also change.

Explanation:

A hypothesis is the assumed explanation for the cause of the natural process. This can be testified on the basis of the experimental process, which will involve the cause and effect relationship between the independent and dependent variables.

The independent variable can be changed in an experiment manually. The impact of such change can be observed on the dependent variable to test the hypothesis.

5. Compare the energy emitted by waves with long <br> wavelengths to waves with short wavelengths
irinina [24]

Explanation:

The energy emitted by long wavelength waves are smaller to those emitted by short wave lengths.

The energy of a wave is a function of its wavelength and frequency.

  • The wavelength of a wave is the distance between its crest.
  • Frequency is the amount of waves that passes through a point in a period of time.
  • Energy of a wave is directly proportional to frequency and inversely proportional to wavelength.
  • The higher the frequency of a wave, the more the energy.
  • Waves with a high wavelength carries very little energy.
  • Long wavelength radiations have a long wavelength as the name implies. They carry very little energy and have low frequency. Examples are infra-red.
  • Short wavelength radiations have short wavelength. They carry very high amount of energy and have very high frequency. Examples are x-rays and gamma rays.

Is evolution a random process? Why or why not.
Bingel [31]

Answer: No

But it is crazy. If Evolution was real things would not be the same as it is today.

Explanation: All life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago, a new study seems to confirm.

Evolution is a theory . Charles Darwin came up with it.

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms. An example of evolution is how cell phones have changed over time.
