Life science is a branch of science, not separate from it. It's like saying "How is a tree related to nature?" A tree is a part of nature, just as life science is a part of science.

Here's a breakdown:

* Science: The systematic study of the natural world through observation, experimentation, and the formulation of testable explanations.

* Life science: A specific area of science that focuses on the study of living organisms and their interactions with their environment.

So, life science is a specific field of study within the broader umbrella of science.

Here's an analogy:

* Science is like a large library with many different sections.

* Life science is one specific section in that library, focusing on books about living things.

Here are some of the ways life science relates to science:

* Scientific Method: Life scientists use the same scientific method as all other scientists – they observe, hypothesize, experiment, and analyze data to draw conclusions.

* Interdisciplinary: Life science is interconnected with other branches of science, like chemistry, physics, and mathematics. For example, understanding how organisms function requires knowledge of chemistry and physics.

* Scientific Progress: Discoveries in life science contribute to the overall advancement of scientific knowledge. For example, the discovery of antibiotics was a major breakthrough in medicine, a field within life science.

In conclusion, life science is not separate from science, but rather a specific and important part of it, focusing on the study of living things and their interactions with the world around them.
