If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?
Afina-wow [57]

The complete question is:

If these organisms were arraigned in a food pyramid, which organism would have the least amount of total energy available?

  • Producers
  • Carnivore
  • Herbivores
  • Top predators

Answer: Top predators

Explanation:

The top predators get the least energy because according to the 10 per cent law the energy transfer only 10 energy is transferred to the next successive level.

The next level of the organism receives only 10 of the total energy that the previous level has.

Hence, the top predators have the least amount of energy in it as the energy is transferred through various levels before reaching top predators.

Can someone explain the process of RNA editing?
Talja [164]
The process of RNA editing is the alteration of the sequence of nucleotides in the RNA after it has been transcribed from DNA, but before it is translated into a protein. RNA editing occurs by two distinct mechanisms:<em><u /><u>Substitution</u> <u>editing </u></em>and <u><em>Insertion/</em></u><em></em><u><em>deletion</em></u><em> <u>editing</u></em>.

<u><em>Substitution editing</em></u> is the chemical alteration of individual nucleotides. These alterations are catalyzed by enzymes that recognize a specific target sequence of nucleotides:

*Cytidine Deaminases that convert a C in the RNA to uracil.

*<em />adenosine deaminases that convert an A to inosine,which the ribosome translates as a G.<span>Thus a CAG codon</span><span> (for Gln) can be converted to a CGG codon (for Arg).

<em><u>*Insertion/deletion editing</u></em><em><u /></em><u /> is the insertion or deletion of nucleotides in an RNA.

These alterations are mediated by guide RNA molecules that base-pair as best they can with the RNA to be edited and serve as a template for the addition( or removal) in the target.</span>
