Answer:

The correct answer is C in presence of oxygen production of acetyl CoA,TCA cycle and electron transport chain occur in a proper order.Whether in absence of oxygen lactic acid fermentation or alcoholic fermentation occurs.

Explanation:

Aerobic respiration occur in presence of oxygen which involves glycolysis,TCA cycle and electron transport chain.Aerobic respiration result in the catabolism of glucose to generate CO2,H2O and ATP.

But in absence of oxygen or during anaerobic condition pyruvic acid is converted to either lactic acid by pyruvate dehydrogenase or to ethanol through alcoholic fermentation.

6. What is the average size of the exons you used to make the coding region? What is the average size of the introns in the gene

cupoosta [38]

Question 1:

Exons are gene fragments whose DNA sequence after transcription is found in mature mRNAs. This part of the gene is most often coding.

The size of the exons in the genomes follows a log-normal distribution, with an average length of about 150 nucleotides, knowing that in eukaryotes, each gene contains several exons and introns (an average of 8) so the size is 8*150 = 1200 bp.

Question 2:

Introns are fragment of a gene located between two exons. Introns are present in immature mRNA and absent in mature mRNA. "Non-coding" fragment of the gene.

The introns average in a gene is 3365 bp including 3'UTR and 5'UTR and intermediate introns.

Can I get some help with 1 and 2

ikadub [295]

For number one, wolves may eat fish instead of larger animals because those larger animals may be going into hibernation and also the berries that a wolf may eat has also gone out of season, leaving the only choice really being fish.

For number two, over harvesting salmon is pretty bad when it comes to the environment. it takes away food from predators, like the wolves in number one, so they lose a source of food and it also takes away the salmons ability to eat the smaller organisms in the stream, so they're going to become overpopulated.
