I am not quite sure what you are asking, but I hope this helps! Cytosine, Guanine, Adenine, and Thymine are nitrogenous bases in DNA. Cytosine and Guanine pair up together, and Adenine and Thymine pair up. Adenine and Guanine are purines and Thymine and Cytosine are pyrimidines.

One explanation of life's origins suggests that meteorites gave way to life on Earth. Which of the following provides evidence t
Nutka1998 [239]

Answer:

The correct answer would be the third option.

One of the hypotheses regarding the origin of life is "organic molecules from outer space".

Under this concept, it is believed that organic compounds might have come on earth through meteorites. Then these organic compounds were used as the precursors of the living cells.

Certain pieces of evidence are also found to support this concept.  

For example, scientists have experimentally proved that conditions like low temperature and high UV radiations (similar conditions as exist in outer space) can result in the production of organic molecules from simple chemical precursors as present in space.

In addition, some organic compounds have also been found in space or other star systems.

When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.
MA_775_DIABLO [31]

When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.

  • It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
  • An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
  • An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
  • Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.
