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.

Based on the model of cellular transport, the hydrolysis of ATP and ADP provide a mechanism for
Ronch [10]

Answer:

<em>Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.</em>

Explanation:

During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.

For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.
