what is the biology ? In the 300-500 words
Answers
Answer:
Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.[1] Despite the complexity of the science, certain unifying concepts consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy[2] to maintain a stable and vital condition defined as homeostasis.
Sub-disciplines of biology are defined by the research methods employed and the kind of system studied: theoretical biology uses mathematical methods to formulate quantitative models while experimental biology performs empirical experiments to test the validity of proposed theories and understand the mechanisms underlying life and how it appeared and evolved from non-living matter about 4 billion years ago through a gradual increase in the complexity of the system.

Science in our Daily Lives
As I have mentioned earlier Science has got many changes in our lives. First of all, transportation is easier now. With the help of Science it now easier to travel long distances. Moreover, the time of traveling is also reduced. Various high-speed vehicles are available these days. These vehicles have totally changed. The phase of our society. Science upgraded steam engines to electric engines. In earlier times people were traveling with cycles. But now everybody travels on motorcycles and cars. This saves time and effort. And this is all possible with the help of Science.
Secondly, Science made us reach to the moon. But we never stopped there. It also gave us a glance at Mars. This is one of the greatest achievements. This was only possible with Science. These days Scientists make many satellites. Because of which we are using high-speed Internet. These satellites revolve around the earth every day and night. Even without making us aware of it.
Science is the backbone of our society. Science gave us so much in our present time. Due to this, the teacher in our schools teaches Science from an early age.

Science as a Subject
In class 1 only a student has Science as a subject. This only tells us about the importance of Science. Science taught us about Our Solar System. The Solar System consists of 9 planets and the Sun. Most Noteworthy was that it also tells us about the origin of our planet. Above all, we cannot deny that Science helps us in shaping our future. But not only it tells us about our future, but it also tells us about our past.
When the student reaches class 6, Science gets divided into three more subcategories. These subcategories were Physics, Chemistry, and Biology. First of all, Physics taught us about the machines. Physics is an interesting subject. It is a logical subject.
Furthermore, the second subject was Chemistry. Chemistry is a subject that deals with an element found inside the earth. Even more, it helps in making various products. Products like medicine and cosmetics etc. result in human benefits.
Last but not least, the subject of Biology. Biology is a subject that teaches us about our Human body. It tells us about its various parts. Furthermore, it even teaches the students about cells. Cells are present in human blood. Science is so advanced that it did let us know even that.
Leading Scientists in the field of Science
Finally, many scientists like Thomas Edison, Sir Isaac Newton were born in this world. They have done great Inventions. Thomas Edison invented the light bulb. If he did not invent that we would stay in dark. Because of this Thomas Edison’s name marks in history.
Another famous Scientist was Sir Isaac Newton. Sir Isaac Newton told us about Gravity. With the help of this, we were able to discover many other theories.
In India Scientists A..P.J Abdul was there. He contributed much towards our space research and defense forces. He made many advanced missiles. These Scientists did great work and we will always remember them
