relationship between “biology” and kinship systems? A. Kinship can be defined as society acknowledging biological connections between people. This view however has been challenged because kinship systems are regarded now as too complex. C. Levi-Strauss (1963) argued; “Kinship…only exists in human consciousness.” The correct way of studying the relationship between biology and kinship systems can only be made by looking at particular societies and cannot be made universally. Biology may have very little

meeting these challenges‚ based on the mechanisms of biology and the principles of physics. Biology studies our life‚ its variety and complexity and physics looks for mathematical laws of nature and makes predictions about the forces that drive idealized systems. The main challenge of Biophysics is to span the distance between the complexity of life and the simplicity of physical laws. In other words biophysics acts as a bridge between biology and physics. Biophysicists’ main job is to study life

How does movie Gattaca relate to biology? The movie Gattaca directed by Andrew Niccol is about “a genetically inferior man assumes the identity of a superior one in order to pursue his lifelong dream of space travel”. During the process (to become as same as Jerome Morrow‚ the superior)‚ Vincent goes through lots of different operations‚ including physical and genetic operations. As we watched it and saw the operations and the doctors in the beginning of the movie‚ we connected happenings to the

The journey to becoming a marine biologist is one that is embarked with hard work and keen determination. When I boarded on this journey as a student majoring in marine biology‚ I have always been fascinated by ocean exploration and how new scientific discoveries have revolutionized around it. I also live with great enthusiasm for conducting oceanic research‚ and I have always envisioned myself using scientific instruments and modern day technologies to conduct such research. The Ocean and Climate

or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940).
