The correct answer is: 4) Standing defenses are always present; induced defenses develop in response to a threat
Induced defense is defense that can be changed or invoked when needed. Induced defenses are slow to happen. When invoked, induced defense requires energy but otherwise doesn’t.
Standing defense is always there. It is use, for example when predation is a constant threat.
1.Net Energy Gain is a concept used in energy economics that refers to the difference between the energy expended to harvest an energy source and the amount of energy gained from that harvest.
In each glycolytic pathway, glyceraldehyde 3-phosphate dehydrogenase produces 1 molecules of NADH as a result of reduction of NAD+.
Pyruvate dehydrogenase converts pyruvate to Acetyl CoA producing 1 molecule of NADH per pyruvate oxidized.
In Kreb's cycle, isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, and malate dehydrogenase reactions produce 1 molecule of NADH each. Furthermore, succinate dehydrogenase reaction produces a single molecule of FADH2 per FAD reduced.
Since, we began with 2 molecules of glyceraldehyde 3-phosphate, we multiply the above figures by 2 and get a total of 10 NADH and 2 FADH2.
The answers are shown below: In part A: coefficient = 20 variable = c constant = 35 & 23.50 In part B: savings = 20 (3) +23.5+ 35+35+35 +35 +35 +35+35+35+35+35+35+35 savings = $ 503.5 In part C: the new expression will be: 25c + 35 + 23.5
