Part II: The Electron Transport Chain 14 NADH and FADH2 enter the electron transport chain after being created during
the Krebs cycle What is their role in the electron transport chain, and what
happens after they fulfill their role?
15 What does the electron transport chain create?
16 What is required for the electron transport chain to operate?
17 What will happen if oxygen is no longer available?
18 Where does the electron transport chain occur?
19 What anves the protons (H+ ions) across the mitochondral membrane to form
ATP

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
