The answer to Question 12 is the fourth one: introns.

Explanation for each option:

  • Exons: These are the portions of eukaryotic mRNA that are retained and expressed after RNA processing. They are not removed.
  • Caps: This refers to the 5' cap added to the mRNA, which is not removed during RNA processing.
  • Poly-A tails: This is a sequence of adenine nucleotides added to the 3' end of the mRNA, which is not removed during RNA processing.
  • Introns: These are the non-coding regions of eukaryotic mRNA that are removed during RNA processing.

For Question 13, the control of gene expression in eukaryotic cells occurs at multiple levels, including transcriptional, post-transcriptional, translational, and post-translational levels. Therefore, the statement "only the transcriptional level" is incorrect.

Part C Because we are ignoring friction, no thermal energy is generated and the total energy is the mechanical energy, the kinetic energy plus the potential energy: E=K+U. Observe the total energy bar on the Bar Graph. As the skater is skating back and forth, which statement best describes the total energy? smallest at the locations where the skater turns to go back in the opposite direction and greatest at the lowest point of the track. The total energy is the same at all locations of the track. greatest at the locations where the skater turns and goes back in the opposite direction and smallest at the lowest point of the track.

Use algebraic techniques to rewrite g(x) = (-5x^(9/4) + 3x^(13/4) + 2) / (x^(1/4)) as a sum of three terms. Then find g'(x).
