What organ is responsible for pumping blood throughout the body?
The heart
What is the pH range of acids?
7 to 1
Define Newton's First Law of Motion
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.
What is the greenhouse effect?
The warming of Earth's surface due to trapped heat by greenhouse gases.
What is the process by which water evaporates from the ocean surface?

Define an endothermic reaction.
A reaction that absorbs heat from its surroundings.
Explain the concept of kinetic energy.
Energy possessed by an object due to its motion
What is an ecosystem?
A community of living organisms and their physical environment interacting as a system.
what is ocean acidification and how does it affect marine life?
It is the decrease in pH of ocean water, affecting organisms like corals and shellfish.
Explain the difference between arteries and veins.
Arteries carry blood away from the heart, while veins carry blood back to the heart.
What is the law of conservation of mass?
What is the difference between speed and velocity?
Speed is magnitude only (scalar), while velocity is magnitude and direction (vector)
Explain the concept of sustainable development.
Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
