What is a dependent variable?

Back

A dependent variable is the variable that is measured in an experiment and is affected by changes in the independent variable. In the context of the provided question, 'bubbles' is the dependent variable.

What does the theory of plate tectonics state?

Back

The theory of plate tectonics states that Earth's crust is divided into sections (plates) that move and interact with each other, leading to geological phenomena.

Why is replication of experiments important in science?

Back

Replication of experiments helps to confirm and verify results, ensuring that findings are reliable and not due to chance.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels large molecules by releasing them from vesicles to the outside of the cell.

What property of water allows insects to skate on its surface?

Back

Surface tension is the property of water that allows insects, like water striders, to skate on its surface.

Front

Define cohesion in the context of water.

Back

Cohesion is the property of water molecules to stick to each other due to hydrogen bonding, which contributes to surface tension.

Front

Define adhesion in the context of water.

Back

Adhesion is the property of water molecules to stick to other substances, which helps in processes like capillary action.

Front

What is the significance of the sea floor spreading in plate tectonics?

Back

Sea floor spreading provides evidence for the movement of tectonic plates, showing how new oceanic crust is formed at mid-ocean ridges.

What happens when two tectonic plates collide?

Back

When two tectonic plates collide, they can create mountains, earthquakes, and volcanic activity due to the immense pressure and friction.
