CSIR NET Life Science Syllabus 2024 This examination is held biannually in June and December. Candidates who wish to pursue their career as a Junior Research Fellow or Assistant Professor in the field of Life Science must appear for this examination.  CSIR NET Life Science Exam Pattern: Marking Scheme  There will be 20, 50, and 75 questions in Parts A, B, and C, respectively, of which candidates are required to answer to 15, 35, and 25 questions. All the questions have four options, out of which only one is right, and hence candidates need to mark only one option as their response. Candidates receive 2 marks for each correct answer in Parts A and B, and 4 marks in Part C. There will be a negative marking of 25% in all the parts. CSIR NET Life Science Exam Pattern: Minimum Qualifying Marks The CSIR NET exam pattern Life Science will help you to score higher than the minimum qualifying marks for the CSIR NET Life Science exam which makes you eligible for the roles of Junior Research Fell

The elemental composition of the human body is a fascinating aspect of biology that reflects the intricate balance of various chemical elements necessary for life. Comprising a complex array of molecules, tissues, and organs, the human body is predominantly composed of a handful of essential elements, each playing a unique role in maintaining health and functioning. The elements in our bodies work together in an amazing way. Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus are like the basic ingredients. They come together to form molecules that make up our bodies, like proteins, carbohydrates, fats, and DNA. These molecules are the building blocks of our cells, tissues, and organs, making sure everything works properly to keep us alive. Understanding what elements make up the human body gives us a deep understanding of how our bodies work. It helps us see how different processes, from how cells use energy to how organs function, are all connected. It shows us how important
