. What is the relationship between quantity demanded and quantity supplied at equilibrium? What is the relationship when there i
Zanzabum

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.

Mitosis &amp; Meiosis: Thinking Scientifically
REY [17]

Answer:

65536 cells

Explanation:

starting from 1 cell at zero minutes  there will be 1 (2^0) cell; 2^0 = 1

after 15 minutes                    there will be 2 (2^1) cells

after another 15 minutes ( 30 min)        there will be 4 ( 2²) cells

after another 15 minutes ( 45 min)         there will be 8 (2³) cells

after n number of 15 minutes                  there will be (2^n) cells

calculate number of 15 minutes in 4 hours

4 hours = 4 × 60 minutes

number ( n) of 15 minutes in 4 hours = (4 × 60 minutes) / 15 minute = 16

using the formula above and substitute 16 for n in the formula

Number of cells = 2 ^n = 2^16 = 65536 cells

Explanation:

 pretty much the structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
