What is the role of a contractile vacuole in protists?

Back

A contractile vacuole helps protists eliminate excess liquid, reducing pressure inside the cell and preventing it from bursting.

Front

What is the primary source of energy for cellular processes in organisms?

Back

ATP (Adenosine Triphosphate) is the primary source of energy for cellular processes.

Front

Which type of cell in the human body is specialized for oxygen transport?

Back

Red blood cells (erythrocytes) are specialized to transport oxygen throughout the body.

Front

What happens to a Paramecium when a chemical is added to its environment?

Back

The Paramecium stops moving, indicating that its movement structures are affected.

Front

What is the energy transfer efficiency from producers to herbivores in an ecosystem?

Back

Typically, only about 10% of the energy from producers is transferred to herbivores.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

Define trophic levels in an ecosystem.

Back

Trophic levels are the hierarchical levels in an ecosystem, representing the flow of energy and nutrients from producers to various levels of consumers.

Front

What is the significance of ATP in cellular respiration?

Back

ATP is produced during cellular respiration and is used as an energy currency for various cellular activities.

Front

Explain the concept of energy pyramids in ecology.

Back

Energy pyramids illustrate the energy flow in an ecosystem, showing the amount of energy available at each trophic level.

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.
