What is the process by which plants make their own food? (Photosynthesis)

Photosynthesis is the process by which plants make their own food. It occurs in the chloroplasts of plant cells, where sunlight is absorbed by chlorophyll. During photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose (sugar) and oxygen. This process is essential for plant growth and is also the main source of oxygen in our atmosphere.

What is the Earth's outermost layer called? (Crust)

The Earth's outermost layer is called the crust.

How does gravity affect the movement of objects on Earth? (Pulls objects towards the center of the Earth)

Gravity affects the movement of objects on Earth by pulling them towards the center of the Earth. This gravitational force is what keeps objects anchored to the ground and influences the trajectory of moving objects, causing them to fall towards the ground when released.

What is the main function of the respiratory system? (To take in oxygen and remove carbon dioxide)

The main function of the respiratory system is to intake oxygen from the air and deliver it to the cells of the body while removing carbon dioxide produced by cellular respiration. This exchange of gases occurs through breathing where oxygen is taken in through inhalation and carbon dioxide is expelled through exhalation.

What is the force that opposes the motion of an object through a fluid? (Drag)

The force that opposes the motion of an object through a fluid is called drag.

How does a solid turn into a liquid? (By melting)

When a solid turns into a liquid through melting, heat is applied to the solid, increasing the kinetic energy of its particles. As the particles gain more energy, they vibrate faster and start to overcome the forces holding them in a rigid, organized structure. Eventually, the particles have enough energy to break free from their fixed positions and move more freely, transitioning the solid into a liquid state.

What are the three states of matter? (Solid, liquid, gas)

The three states of matter are solid, liquid, and gas.

What causes seasons on Earth? (The tilt of the Earth's axis)

The tilt of the Earth's axis is what causes seasons on Earth. As the Earth orbits the Sun, different parts of the planet receive varying amounts of sunlight depending on their positioning relative to the Sun. This tilt is responsible for the changes in seasonality as different regions experience either more direct or indirect sunlight, leading to the different seasons we observe throughout the year.

What is the function of the circulatory system? (To transport oxygen, nutrients, and waste throughout the body)

The function of the circulatory system is to transport oxygen, nutrients, and waste throughout the body. It does this by pumping blood through a network of blood vessels, including arteries, veins, and capillaries, to deliver oxygen and nutrients to cells and tissues and remove waste products from the body.

How do magnets attract or repel other magnets? (Through magnetic fields)

Magnets attract or repel other magnets through their magnetic fields, which are created by the alignment of their magnetic dipoles. When two magnets are brought close together, their magnetic fields interact either by attracting if the poles are opposite (north and south poles) or by repelling if the poles are the same (north and north or south and south poles). This interaction is a result of the forces exerted by the magnetic fields, causing the magnets to either come together or push apart depending on their orientation.
