* Describe at what point in the cell cycle cells begin to divide uncontrollably.
Butoxors [25]

Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury. Different cells grow and die at different rates. Some cells, such as epithelial<span>epithelialA thin layer of epithelial cells that makes up the outer surfaces of the body (the skin) and lines hollow organs, glands and all passages of the respiratory, digestive, reproductive and urinary systems.</span> cells, reproduce quickly. Other cells, like nerve cells, grow slowly. Both normal cells and cancer cells go through a sequence of steps, or phases, when they form new cells. This is called the cell cycle.

. 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.
