What is one of the unifying themes of biology?

Back

All living organisms transform energy.

Front

How does evolution contribute to our understanding of biology?

Back

Evolution helps us understand the unity and diversity of life.

Front

How does cortisol likely cross biological membranes?

Back

Cortisol likely crosses biological membranes by passive diffusion due to its steroid nature.

Front

Define adhesion in the context of water properties.

Back

Adhesion is the attraction between water molecules and other substances, which helps in processes like capillary action.

Front

What are the 'Big 4' elements essential for life?

Back

The 'Big 4' elements are Carbon, Hydrogen, Oxygen, and Nitrogen.

Front

What is the significance of energy transformation in living organisms?

Back

Energy transformation is crucial for maintaining life processes, such as metabolism and growth.

Front

What does it mean that all living organisms interact with their environment?

Back

It means that organisms respond to environmental changes and influence their surroundings, which is essential for survival.

Front

Explain the concept of evolution in biology.

Back

Evolution is the process through which species change over time through natural selection and genetic variation.
