There are 2 fundamental theoretical approaches detailing the origin of the cell: purely naturalistic, and theistic. The naturalistic approach involves a number of possible theories, the goal being to find the simplest combination of critical functional elements that could be called a living entity and not requiring a cell membrane, rather some form of metabolically and reproductively viable configuration that could be called the first lifeform. This is considered marginally viable as the cell membrane is essential for holding the cell together, protecting the interior, and allowing the outflow and influx of chemicals necessary for cellular function. A more challenging and less substantiated theoretical approach with a number of theories calls for all atoms of the chemical elements needed for the construction, operation, and reproduction of the first cell overtime collect and interact at increasingly higher levels of complexity until a complete cellular entity results. Neither answers the question how the non-living material collected actually comes alive.

The theistic approach proposes that God designed the total requirements for the first cellular life then set the conditions for its elemental collection, biochemical assembly and ultimate transition to a living entity.The viability of this approach is high considering the problems it solves:
1. The non-existence of any natural processes or forces to accomplish the total cellular assembly or transition to living status.
2. The absence of any combination of conditions that could colocate, coincide, concentrate, and mitigate contamination of required elements.
3. Resolve the creation and assembly of homochiral amino acids with homopolymer sugar backplanes.
4. Create and code the DNA, RNA and proteins required for cellular operation and reproduction. DNA and RNA are made of proteins but DNA is required to produce proteins.
5. Create and assembly the cell membrane that accomplishes all the required functions.
6. The accomplishment of all the above under environmentally stressful conditions of the primordial Earth.

Much more could be added.

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
