What is a line graph used for?

Back

A line graph is used to display data points over time, allowing for the analysis of trends, directions, and slopes to make predictions about future data.

Front

How can you determine the difference in values using a bar graph?

Back

By comparing the heights of the bars representing different categories, you can determine the difference in values.

Front

What laboratory equipment is used for holding and mixing liquids?

Back

A beaker is used for holding and mixing liquids in a laboratory setting.

Front

What is dynamic equilibrium?

Back

Dynamic equilibrium occurs when particles are moving into and out of a cell, but their concentrations remain stable.

Front

What does it mean for a cell membrane to be selectively permeable?

Back

A selectively permeable membrane allows certain substances to pass through while blocking others, regulating the movement of materials in and out of the cell.

Front

What is the purpose of a measuring cylinder?

Back

A measuring cylinder is used to accurately measure the volume of liquids.

Front

What is the difference between hydrophilic and hydrophobic substances?

Back

Hydrophilic substances are attracted to water, while hydrophobic substances repel water.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, which can drive the movement of particles.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the function of a conical flask?

Back

A conical flask is used for mixing, heating, and storing liquids, and its shape helps to minimize evaporation.
