Chapter 4 The Chemical Basis of Life Introduction Your body is an elaborate chemical system. Chemical signals between brain less enable your mind to understand what you see. You nourish those cells with chemicals that are obtained from food. Life is all about chemicals and how they interact Concept 4.1 Life requires about 25 chemical elements Elements Humans and other organisms are examples of matter.

What is Life? This perennial question the answer to which has somehow eluded the most brilliant minds. For while scientists have identified many years ago the right mix of the atoms and molecules that constitute cellular material‚ they have not succeeded in ‘switching it on’ to make it alive‚ or ‘breathing life’ into it (Rabago et.al‚2006) In this module you will: a. Explain the concepts of the cell theory b. Identify the parts of a cell c. Describe the function of each cell part d. Differentiate

Many terms have been used in connection with conceptual contexts for research‚ including theories‚ Models‚ frameworks‚ schemes and maps. There is some overlap in how these terms are being used‚ partly because they are used differently by different writers‚ partly because they are interrelated. Theories The term theory is used in many ways. For example‚ nursing instructors and students frequently use the term to refer to the content covered in classrooms‚ as opposed to the actual practice of
