Question:
In the process of cellular respiration, glucose and oxygen undergo chemical reactions to form new molecules. Select the correct sequence of events that describe how food is rearranged through these reactions to support the growth and release energy in an organism.
Answer Choices:
- A) Glucose and oxygen react to form carbon dioxide, water, and ATP.
- B) Glucose is broken down into oxygen, which combines with carbon dioxide to form ATP.
- C) Oxygen is converted into glucose and water, releasing carbon dioxide and energy.
- D) Carbon dioxide and water are rearranged to form glucose, releasing energy.
💡 Explanation:
- In cellular respiration, glucose and oxygen are the reactants that undergo chemical reactions in the mitochondria of cells.
- These reactions form carbon dioxide, water, and ATP (adenosine triphosphate), which provides energy for cellular processes and supports growth.

Question:
A cone and a hemisphere have equal volumes. The height of the cone is 9 cm. Determine the radius of the hemisphere if the radius of the cone is 3 cm. Use the formulas for the volumes of a cone and a hemisphere to solve this problem and explain your reasoning.
💡 Explanation:
The volume of a cone is given by the formula V = (1/3)πr²h, where r is the radius and h is the height.
For the cone with radius 3 cm and height 9 cm, the volume V is (1/3)π(3)²(9) = 27π cubic centimeters.
The volume of a hemisphere is (2/3)πR³, where R is the radius of the hemisphere.
Setting the volumes equal for the cone and the hemisphere, we get 27π = (2/3)πR³.
Solving for R gives R³ = 40.5, so R = 3 cm.
