LIFE SCIENCE

Life Science Life science provides us information about one of the most important things to us. From the smallest microbe to the largest mammal, Life Science explores the origins of evolution and expansion of life in all its forms. This are of science explores a wide range of topics from animal profiles to genetics and conservation. This branch of science is often categorized under the name Biology which examines the structure, function, growth, origin, evolution, distribution and classification of all living things. There are five basic principles which form the foundation of modern biology, which include: cell theory, evolution, gene theory, energy and homeostasis.

Cell Theory – A widely accepted explanation of the relationship between cells and the living things that they comprise. The cell theory states:

  1. All living things are comprised of one or more cells.
  2. A cell is the most basic unit of life.
  3. All cells come from other cells.

Evolution – Not meant to refer necessarily to how human beings came to be, but more in the terms of change and adaptation of these beings over time and from generation to generation, looking at the complete changes to the makeup of human beings over centuries of study.

Gene Theory – This study involves the study of genes and DNA and RNA as it passed from parents to children, and includes the study of likelihood of inheritance as well as genes predisposed for illness and malformation.

Energy – The study of this force as it can be transmitted from one source to another as well as the understanding of stored energy (potential) vs. the energy of actual motion (kinetic).

Homeostasis - The ability or tendency of an organism or cell to maintain internal equilibrium by adjusting its physiological processes. This includes factors like fight or flight response, adaptations of certain creatures to their environment as well as adaptations and regulation of bodily functions as seen in hormone secretions and temperature changes.

Some of the branches of life science and biology are:

  • Botany – The study of plants
  • Zoology – The study of animals
  • Microbiology - The study of microorganisms
  • Biochemistry – Study of the fundamental chemistry of life
  • Molecular Biology – Study of the complex interactions of systems of biological molecules
  • Cellular Biology – The study of the basic building blocks of all life
  • Physiology – Studies the physical and chemical functions of tissues and organs in a system
  • Ecology – Examination of how organisms interact with their environment

LIFE SCIENCE AS IT AFFECTS YOUR WORLD

One of the biggest things that life science brings to the world as we know it is modern medicine. Life Science no only affects the study of the body and how illness occurs, but also in study of genetics that allow us to find predisposition to certain diseases and traits in advance. In addition to this our criminal justice system has been significantly impacted by this area of science as well in the way that they can now match DNA reference samples to DNA from saliva, blood and other bodily secretions found at crime scenes. This allows criminals to be accurately pinpointed for their crimes.
