Concept 1.2 Lecture Video and Quiz

What is the primary focus of the video tutorial?

• Photosynthesis

• Homeostasis and Regulation

• Genetics

• Cell Division

What is the foundational concept discussed in the video?

• Genetics

• Photosynthesis

• Homeostasis and Regulation

• Cell Division

What does homeostasis refer to?

• The process of cell division

• The stability of the internal environment

• The creation of new cells

• The breakdown of food

What is the significance of maintaining stability in the internal environment?

• To prevent any change

• To ensure constant change

• To keep it within a target range

• To allow for random fluctuations

What is maintained in a dynamic equilibrium?

• Rate of food intake

• Rate of photosynthesis

• Rate of loss and gain

• Rate of cell division

What is the term used to describe the balance between the rate of loss and gain?

• Homeostasis

• Regulation

• Dynamic equilibrium

• Static equilibrium

Why is equilibrium described as dynamic instead of static?

• Because it is unpredictable

• Because it never changes

• Because it involves constant change

• Because it is always the same

What does the term 'dynamic' imply in the context of equilibrium?

• Unpredictable

• Always the same

• Involving change and flow

• Constant and unchanging

What is the goal of maintaining equilibrium within a certain range?

• To prevent any change

• To allow for random fluctuations

• To keep it within a target range

• To ensure constant change

Why is it acceptable for equilibrium to fluctuate slightly above or below the target?

• Because it is constant

• Because it is static

• Because it is unpredictable

• Because it is dynamic
