Are you looking for Chapter 1 Introduction To Biology Notes in PDF? You are at the right place. You can download the complete exercises, numerical, short questions and MCQs of the unit 1.

In this first chapter, the basic of Biology is explained with short and long questions. All the definition of the Biology branches that give you the basic understanding of the future jobs that you can get. Then the most important question, “What are bio elements?”, and its answer is depicted in the notes. Then another critical topic level of organizations is often asked in the exams. 

A biologist studies living things. The principles discovered in biology apply to all organisms—from the simplest single-celled bacteria to complex plants and animals, including humans. Other sciences, such as chemistry and physics, are concerned with inanimate objects.

The field of biology is vast and includes many subdisciplines or subtopics. 

These include botany (the study of plants), zoology (the study of animals), microbiology (the study of microorganisms), physiology (the study of body function), genetics (the study of heredity and variation), ecology (how living things interact with the environment), and evolution (the proposed changes in living things over long periods).

There are two kinds of science: speculative and investigative.

Investigative science is what most people mean by “science.” It’s examining the world, seeing what’s there, and trying to figure out how things work. It’s what scientists do.

Investigative science is the opposite of speculative science. Speculative science is starting with some idea you want to be accurate, then trying to explain it.

Speculative science can be fun. But because it’s not a very good way to learn about nature, we don’t call it “science.” We call it “science fiction.”

So why should we care about speculative biology? Because theoretical biology is also called “life on Earth.”
