Front

What is the bonding pattern that cannot be formed by carbon?

Back

Carbon can form single, double, and triple bonds, but it cannot form quaternary bonds.

Front

What property of water allows plants to transport water from roots to leaves?

Back

The attraction between molecules (cohesion) is responsible for water transport in plants.

Front

What is the role of ATP in a paramecium?

Back

ATP provides the energy to move cilia.

Front

What function do the porous linings of lungs and capillaries serve?

Back

They facilitate gas exchange.

Front

How do carbohydrates and nucleic acids differ in function?

Back

The bonds in a carbohydrate store energy, while the sequence of nucleotides in a nucleic acid stores genetic information.

Front

Define cohesion in the context of water properties.

Back

Cohesion is the attraction between water molecules, which helps in the transport of water in plants.

Front

What is the significance of ATP in cellular processes?

Back

ATP is the primary energy carrier in cells, providing energy for various biochemical reactions.

Front

Explain the process of gas exchange in lungs.

Back

Gas exchange occurs when oxygen is absorbed into the blood and carbon dioxide is released from the blood into the lungs.

Front

What are the main components of nucleic acids?

Back

Nucleic acids are made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.

Front

Describe the structure of carbohydrates.

Back

Carbohydrates are composed of sugar molecules (monosaccharides) linked together, often in chains.
