Document Summary

Principles of life: distinguish living things from non-living things: cells are the simplest units of life/organization. Organisms maintain internal order (homeostasis) different from the environment. Levels of organization: atom: smallest component of an element with all chemical properties, molecules and macromolecules: atoms bond to form molecules, molecules then form macromolecules. In evolution, structure is often modified for new purpose. Two types of changes through evolution: vertical descent with mutation and horizontal gene transfer. Vertical descent: changes in a series of changes through series of ancestors (lineage). Called vertical descent because of how it"s usually depicted. Become a species by mutation (inheritable change in genetic material). Horizontal gene transfer: genetic exchanges occurring between different species, especially bacteria. Sub discipline of biology in attempt to determine relatedness. Bacteria and archaea are prokaryotic microorganisms that still show differences in lipid organization, packaging of heretic material, regulation of production of mrna. Eukarya are eukaryotic with larger cells with genetic material with membrane.

Consider a group of humanoids like Geth, an imaginary group of artificial intelligence as seen in video game franchise Mass Effect ( http://masseffect.wikia.com/wiki/Geth) that gained sentience, consist of individually operating physical units that have a compute unit not only acting individually but share a common network for thought processing and decision making. Considering the properties of life as discussed in Campbell Biology Chapter 1, would you consider Geth as living or not? Explain your reasoning via discussing at least 1 aspect/property of life. !!! Properties of life are:

Order. Organisms are highly organized structures that consist of one or more cells. ...

Sensitivity or Response to Stimuli. Organisms respond to diverse stimuli. ...

Reproduction. ...

Adaptation. ...

Growth and Development. ...

Regulation. ...

Homeostasis. ...
