8. If the killer whale obtained 26,000 Joules of energy by eating the crabeater seal, how much energy was
available at each of the following trophic levels of the food chain?
Algae → Krill → Adelie Penguin → Crabeater Seal

According to the Ecological tithe law, if the Killer whale obtained 26,000 joules from Crabeater Seal, the amount of energy available in each link in the chain was:

Explanation:

The energy obtained by the killer whale was 26,000 joules, or 26 Kilojoules (1000 joules = 1 Kilojoule) and corresponds to 10% of the energy available in the previous link in the chain.

In ecology and trophic chains, according to the 10% law -also called the Ecological tithe law- the amount of energy available that is transferred at each level of the chain is equivalent to 10% of the previous level.

If one takes into account that the amount of energy obtained by the final link, in this case the killer whale was 26,000 joules, it can be said that at the previous level the available and transferred energy was 10 times greater:

Finally, the killer whale only obtained a fraction of the energy that was initially available in the Algae.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
