Which is better modern life or past life

Hello Lazer Thanks for your essay. How long did it take you to write? Many students are tired by the time it comes to do Task 2. Sentence Length - write more short sentences, and fewer long ones.

Which is better modern life or past life

Organism The characteristics of life Since there is no unequivocal definition of life, most current definitions in biology are descriptive. Life is considered a characteristic of something that preserves, furthers or reinforces its existence in the given environment.

This characteristic exhibits all or most of the following traits: Living things require energy to maintain internal organization homeostasis and to produce the other phenomena associated with life. A growing organism increases in size in all of its parts, rather than simply accumulating matter.

This ability is fundamental to the process of evolution and is determined by the organism's hereditydiet, and external factors. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun phototropismand chemotaxis.

These complex processes, called physiological functionshave underlying physical and chemical bases, as well as signaling and control mechanisms that are essential to maintaining life.

Alternative definitions See also: Entropy and life From a physics perspective, living beings are thermodynamic systems with an organized molecular structure that can reproduce itself and evolve as survival dictates. One systemic definition of life is that living things are self-organizing and autopoietic self-producing.

Variations of this definition include Stuart Kauffman 's definition as an autonomous agent or a multi-agent system capable of reproducing itself or themselves, and of completing at least one thermodynamic work cycle.

Virus Adenovirus as seen under an electron microscope Whether or not viruses should be considered as alive is controversial. They are most often considered as just replicators rather than forms of life. However, viruses do not metabolize and they require a host cell to make new products.

Virus self-assembly within host cells has implications for the study of the origin of lifeas it may support the hypothesis that life could have started as self-assembling organic molecules.

Biophysicists have commented that living things function on negative entropy. These systems are maintained by flows of information, energyand matter. Some scientists have proposed in the last few decades that a general living systems theory is required to explain the nature of life.

Instead of examining phenomena by attempting to break things down into components, a general living systems theory explores phenomena in terms of dynamic patterns of the relationships of organisms with their environment. Gaia hypothesis The idea that the Earth is alive is found in philosophy and religion, but the first scientific discussion of it was by the Scottish scientist James Hutton.

Inhe stated that the Earth was a superorganism and that its proper study should be physiology. Hutton is considered the father of geology, but his idea of a living Earth was forgotten in the intense reductionism of the 19th century.

Nonfractionability The first attempt at a general living systems theory for explaining the nature of life was inby American biologist James Grier Miller. Specifically, he identified the "nonfractionability of components in an organism" as the fundamental difference between living systems and "biological machines.

Morowitz explains it, life is a property of an ecological system rather than a single organism or species. Robert Ulanowicz highlights mutualism as the key to understand the systemic, order-generating behavior of life and ecosystems.

Mathematical biology Complex systems biology CSB is a field of science that studies the emergence of complexity in functional organisms from the viewpoint of dynamic systems theory.

A closely related approach to CSB and systems biology called relational biology is concerned mainly with understanding life processes in terms of the most important relations, and categories of such relations among the essential functional components of organisms; for multicellular organisms, this has been defined as "categorical biology", or a model representation of organisms as a category theory of biological relations, as well as an algebraic topology of the functional organization of living organisms in terms of their dynamic, complex networks of metabolic, genetic, and epigenetic processes and signaling pathways.

The underlying order-generating process was concluded to be basically similar for both types of systems.Jun 10,  · Re: Ancient Times or Modern Times - Which is better? - June 10th, This is contradiction question, in related to development, modern time is much better but, as compare to health and food, ancient time was way pure and healthy.
