A student wants to add an arrow between the reactions shown to model how the two systems work together to cycle carbon among Earth's systems. Which change could be made to the model to
BEST represent the flow of carbon between photosynthesis and cellular respiration?
A
Add an arrow pointing from the product side of the photosynthesis reaction to
the reactant side of cellular respiration.
B
Add an arrow pointing from the reactant side of the photosynthesis reaction to
the reactant side of cellular respiration.
с
Add an arrow pointing from the product side of the photosynthesis reaction to
the product side of cellular respiration.
D
Add an arrow pointing from the reactant side of the photosynthesis reaction to
the product side of cellular respiration.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
