During cellular respiration, OXYGEN serves as an electron acceptor and Adenosine triphosphate (ATP) is produced. during photosynthesis, WATER serves as an electron donor and oxygen molecules, hydrogen ions and electrons are produced.
Cell wall is the structure in the leaf cell that is responsible for this difference.
Out of the photosynthesis (plants).
The continental plate is thicker and less dense while the oceanic plate is thinner and more dense.
Answer:
- At equilibrium, the quantity of a commodity demanded is the same as the quantity of that commodity supplied. i.e. QD = QS. The price at which QD = QS is the equilibrium price.
- When there is a shortage, the quantity of goods demanded would be greater than quantity supplied, as the price falls below the equilibrium price. i.e. QD>QS
- When there is surplus, the quantity of goods demanded is less than the quantity supplied, as price increases above the equilibrium price. i.e. QD<QS.
For example, in the table showing the demand and supply schedule for T shirt at different prices (see file attached), the equilibrium price for a unit of T shirt is $3, at equilibrium, QD = QS (i.e. 30 = 30).
A shortage is recorded when the price of T shirt falls below equilibrium price of $3 as shortage of T shirt is recorded, i.e. @ $2, QD>QS (40>20). A shortage of 20 is recorded.
Surplus occurs as price increases above equilibrium price of which QD<QD, i.e. @ $4, a surplus of 20 is recorded.
