Front

What is Filicinophyta?

Back

Filicinophyta, commonly known as ferns, are a group of vascular plants that reproduce via spores and have neither seeds nor flowers.

Front

What is the primary function of lipids in the human body?

Back

Lipids serve as long-term energy storage, insulation, and make up cell membranes.

Front

What is a property of water that is crucial for life?

Back

Water molecules are highly cohesive, which is important for transport in xylem.

Front

What is anaerobic respiration?

Back

Anaerobic respiration is a type of respiration that occurs without oxygen, resulting in the production of energy and byproducts like lactate in humans.

Front

What evidence did Meselson and Stahl provide?

Back

They provided evidence for the semi-conservative replication of DNA, demonstrating that each new DNA molecule consists of one old strand and one new strand.

Front

What is the role of cohesion in water?

Back

Cohesion allows water molecules to stick together, which is essential for processes like water transport in plants.

Front

What is the waste product of anaerobic respiration in humans?

Back

Lactate is the waste product of anaerobic respiration in humans.

Front

What are the main components of the fluid mosaic model of membrane structure?

Back

The fluid mosaic model describes the cell membrane as a dynamic structure composed of a phospholipid bilayer with embedded proteins.

Front

What is the significance of specific heat capacity in water?

Back

Water has a high specific heat capacity, meaning it can absorb a lot of heat without a significant change in temperature, which helps regulate climate.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy, while anaerobic respiration occurs without oxygen and produces less energy.
