organism: A contiguous living system that can metabolize, grow, respond to stimuli, reproduce, and adapt to its environment.extremophile: A microorganism that can survive in extreme environmental conditions.These include carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur-the elemental macronutrients for all organisms-often represented by the acronym CHNOPS. All life forms require certain core chemical elements for biochemical structure and function.Extremophiles can survive exposure to such conditions for weeks, months, years, or even centuries. Organisms called extremophiles can assume forms enabling them to withstand freezing, dehydration, starvation, high levels of radiation, and other physical or chemical challenges.
Migration and hibernation are two examples of these adaptations. Organisms cannot perform these functions as well or at all outside of these conditions, but some organisms have developed ways to adapt to environmental changes. Living organisms have ranges of ecosystem conditions where they can perform all physiological functions of life.The nonliving (abiotic) components of an ecosystem include energy, oxygen, water, nutrients, and temperature.Nonliving things are either living things that have died or inanimate objects that were never alive.Living organisms are systems made from cells and are capable of life functions such as reproduction, metabolism, response to stimuli, and homeostasis.
It seems most useful for providing depth to key points with direct links to sub-pages within this course.
Lumen learning boundless anatomy and physiology full#
Student could likely meet their learning goals and interests with this material as a support (curated by the instructor) to an existing course but it likely does not standalone as a full course resource. This material generally ages well, it just needs to be paired with continually more updated and relevant examples as technologies and markets change. Most of the material is relevant to any Introductory Business course with concepts that would apply for a long period of time. Since Lumen owns this material, it is likely to be here in this state for a long while. Lumen has taken some responsibility for the fact that it can still be edited but likely not updated to increase its currency. This material is published as CC-Sharealike so it can be remixed but not revised. It is limited in terms of interactivity and is still a text heavy presentation. The text includes detailed images and graphs that are well done and help drive home visual concepts. An instructor could easily remix this with more current, relevant, and culturally deeper examples. There does not appear to be a great deal of bias with this work, since its positioning is relatively generic to the facts and figures and it typically steers clear of opinions and judgments. A few of the examples given in the text could be a bit dated, which indicates that its utility may come from linking to specific parts of the course rather than using it as an entire textbook substitute.
The material presented in this resource is generally accurate especially considering that it reflects standard business practices and concepts that have changed little. This is an entire course/e-textbook that was formerly the Boundless Business text that was purchased by Lumen Learning and maintained in its current form.
From its earliest beginnings, biology has restled with these questions: What are the shared properties that make something “alive”? And once we know something is alive, how do we find meaningful levels of organization in its structure? Similarly, some biologists study the early molecular evolution that gave rise to life since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term. Consequently, virologists are not biologists, strictly speaking. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life.
