CD Semester 1 Biology Review 24-25

Front

What happens to the amount of CO₂ in the atmosphere if the process of photosynthesis increases?

Back

Decreases

Front

What type of feedback loop amplifies the response?

Back

Positive feedback loop

Front

What factor increases the rate of photosynthesis when the temperature is hotter (but not too hot)?

Back

Hotter Temperature

Front

What process allows fish to remove O2 from the water during gas exchange?

Back

Diffusion, Moves from high to low concentration

Front

Which human body system is responsible for gas exchange?

Back

Respiratory System

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose and oxygen.

Front

Explain the difference between osmosis and diffusion.

Back

Osmosis is the movement of water across a semipermeable membrane from low to high solute concentration, while diffusion is the movement of particles from high to low concentration.

Front

What is a negative feedback loop?

Back

A process that counteracts a change, reducing the output or activity to maintain balance.

Front

What is the primary function of the circulatory system?

Back

To transport oxygen, nutrients, hormones, and waste products throughout the body.
