• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

• The force acting on an object is equal to its mass times its velocity (F = mv).

• An object in motion will stay in motion unless acted upon by an equal force.

What is the role of mitochondria in a cell?

• Mitochondria store genetic information for the cell.

• World War I primarily strengthened existing empires without change.

What is the difference between mitosis and meiosis?

• Mitosis results in genetic variation; meiosis results in identical cells.

• Mitosis produces two identical cells; meiosis produces four genetically diverse gametes.

• Mitosis occurs only in plant cells; meiosis occurs in animal cells.

• Mitosis produces four identical cells; meiosis produces two genetically identical gametes.

Explain the concept of supply and demand in economics.

• Supply and demand are unrelated concepts.

• Supply is the quantity of goods available for sale, and demand is the quantity of goods consumers are willing to purchase. Their interaction sets market prices.
