19. a cell is ready to break down pyruvate
and use it for energy. the end result of the
process includes carbon dioxide, atp, and
byproducts. which energy producing
pathway did the cell follow?
o a. cellular respiration
o b. acellular respiration
o c. krebs's pathway
o d. fermentation

The correct option is C. The cell followed Kreb's pathway.

Explanation:

Krebs cycle can be described as a metabolic pathway for the release of energy during the process of aerobic respiration. The Kreb's cycle constitutes a series of oxidation reactions through which pyruvate is converted into carbon dioxide. About 15 moles of ATP is released as a result of Kreb's cycle. The reactions of the Kreb's cycle take place mostly in the mitochondria. The Kreb's cycle is commonly named as the Citric Acid Cycle.

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…

explanation:

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
