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.

The antiparallel arrangement within DNA molecules refers to Select one:
mylen [45]

Answer:

c. one helix strand that runs from the 5' to 3' direction and the other strand runs from the 3' to 5' direction.

Explanation:

A DNA molecule has <em>two strands of nucleotides with a sugar phosphate backbone each, but orientated on the opposite direction </em>allowing for the base pairs to complement one another, making it a more stable structure. <em>When two biopolymers run parallel to each other but with opposite directionality (alignment) we have an antiparallel arrangement.</em>

I annexed an image of the DNA structure.

I hope you find this information useful and interesting! Good luck!

Define Heat, Thermal Energy, Conduction, Convection and Radiation
Leya [2.2K]
Heat:  it is a form of energy associated with the movement of atoms and molecules in any material.<span>The higher the temperature of a material, the faster the atoms are moving, and hence the greater the amount of energy present as </span>heat<span>. 

Thermal Energy: t</span>he internalenergy<span> of an object due to the kinetic </span>energy<span> of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic</span>energy<span> than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion.

Conduction: </span><span>the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

Convection: </span>the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

Radiation: the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Hope this helped :)
