The answer is B An observation about the number or amount of something
Answer;
"couples" energetically unfavorable reactions to ATP condensation in order to drive the reaction toward the required product.
Explanation;
-Metabolic pathways are designed to synthesize necessary cellular reagents as required for cellular and tissue function. To accomplish this, the reaction sequence includes both reactions that are essentially irreversible and reactions that are freely reversible (near equilibrium).
-In most cases, cells use a strategy called reaction coupling, in which an energetically favorable reaction (like ATP hydrolysis) is directly linked with an energetically unfavorable (endergonic) reaction.
Answer:
Crocodiles and snakes are more alike since they both develop from an egg.
Lizards and snakes are more alike since both species have a recent common ancestor.
