Given that the main reason for which an artist will retrace a drawing in pen is to <u>correct errors </u>and achieve a <u>final draft</u>, we can compare this to the biological process of DNA proofreading.
DNA proofreading is a <u>biological process </u>that takes place during the biosynthesis of DNA. During this time, a chain of <u>DNA </u>is read and a complementary chain is creating, <u>effectively duplicating the genetic code</u>.
During this process, DNA proofreading takes place. This is described as a process in which the DNA polymerase retraces the genetic code, detecting and fixing any errors in the synthesis before the strand is closed once again.
The fact is that both processes, despite taking place in astronomically different situations, share a final goal which is to prepare the "product" for the "final draft". This allows us to draw <u>valid</u> <u>comparisons </u>between the retracing of a <u>cartoon </u>and the <u>proofreading </u>of <u>DNA </u>by the DNA polymerase enzyme.

Answer:
I'd say an exoskeleton.
Explanation:
My main reason for saying this is because bugs with exoskeletons survive much better than bugs with endoskeletons or (surprise surprise) no skeletons. If your skeleton is outside your body, it protects everything inside you. Endoskeletons merely help hold you together.

Wind will blow from on location to another.

Answer:
2 molecules of ATP and 2 molecules of NADH
Explanation:
Glycolysis is the first step of cellular respiration (break down of glucose to extract energy) which occurs in the cytoplasm. Glycolysis is a pathway common to all living organisms- prokaryotes and eukaryotes, as it does not require oxygen to occur.
Glycolysis occurs in two major phases (ten steps) requiring 10 enzymes catalyzing each step; the energy-requiring phase and the energy-requiring phase.
In the energy-requiring phase, the starting molecule (glucose) gets rearranged in a series of chemical reactions, and two phosphate groups gets attached to it producing fructose-1,6-bisphosphate which is unstable, This modified sugar then splits in half due to its instability to form two different but inter-convertible phosphate-bearing three-carbon sugars (Dihydroxyacetonephosphate, DHAP and Glyceraldehyde-3-phosphate, G3P). Because the phosphates used in these steps come from 2 ATP molecules, 2 ATP molecules get used up in this phase
All the DHAP molecules get converted to G-3-P in order to enter the next phase.
In the energy-recovering phase, the 3-carbon sugar (G3P) is converted into another three-carbon molecule called pyruvate, through a series of reactions. In these reactions, two ATP and 1 NADH molecules are made. This recovery phase occurs twice (one for each of the two isomeric three-carbon sugars, DHAP and G3P). Hence, a total of 4 ATP and 2 NADH molecules are produced in this phase.
Overall, Glycolysis converts one glucose (six-carbon) molecule to two pyruvate (three-carbon) molecules and a net release of 2 ATP molecules (4 overall - 2 used) and 2 NADH molecules.
