Take a few minutes to think about all of the advancements that our society has achieved as a function of research involving animal subjects. how have you, a friend, or a family member benefited directly from this kind of research?

Because testing and research done on human beings has been not accepted either by the scientific community, or society at large, the only other tool that could be used in order to answer questions as to how to make human life easier, was through animal research. As such, science chooses animals that are genetically similar to human beings, in order to test their theories, and thus generate results that become either products, or services, that improve human life.

Such is the case of medicine, and pharmacology. Although pharmacology´s origin is from plants, many of these chemicals could not be tested on human beings because of ethical, and humanitarian issues, and therefore, the only other, and best option, was to use animals. Thus, many laboratories have developed many of the substances that today save human lives thanks to these animals that were used in research.

An example like this was the development of insulin. An enzyme produced by the human body normally, but that in pathological situations, may be either faulty, or absent totally, is now produced thanks to research on animals whose insulin, and bodies, are used for both extraction and also testing.

Like this, many other such advances have been made in the medical field and have benefited families, and friends.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
