The role of biology and physiology

I modified it slightly and have posted it here. Out-of-class activity includes the op-ed articles being reviewed by classes at the local middle school, and thank you notes written to each reviewer. In doing so he was the first to indicate the homology between the arrangements of bones and joints in the leg of the human and that of the horse, despite the superficial differences.

Because Aquinas was a rationalist, he declared that God created the reasoning mind; hence, by true intellectual processes of reasoning, man could not arrive at a conclusion that was in opposition to Christian thought.

Like Aristotle, Theophrastus was a keen observer, although his works do not express the depth of original thought exemplified by his teacher. The development of the microscope The magnifying power of segments of glass spheres was known to the Assyrians before the time of Christ; during the 2nd century ce, Claudius Ptolemyan astronomer, mathematician, and geographer at Alexandria, wrote a treatise on optics in which he discussed the phenomena of magnification and refraction as related to such lenses and to glass spheres filled with water.

In the past time, it has been limited in studying activities of viruses and bacteria. Earliest biological records Biological practices among Assyrians and Babylonians Much of the earliest recorded history of biology is derived from Assyrian and Babylonian bas-reliefs showing cultivated plants and from carvings depicting veterinary medicine.

Because these interrelationships are so important to the welfare of Earth and because they can be seriously disrupted by human activities, ecology has become an important branch of biology.

Although the Arabic scholars themselves were not great innovators, they discovered the works of such men as Aristotle and Galen, translated those works into Arabic, studied them, and wrote commentaries about them. In his great work, De historia et causis plantarum The Calendar of Flora,in which the morphology, natural history, and therapeutic use of plants are described, Theophrastus distinguished between the external parts, which he called organs, and the internal parts, which he called tissues.

Most recently, evolutionary physiology has become a distinct subdiscipline. Animal physiology plays a role of the work of various organs of the body which those organs coordinate to integrate the animal behavior.

Not until optical instruments were sufficiently developed to reveal cells, however, was it possible to formulate a general hypothesisthe cell theory, that satisfactorily explained how plants and animals are organized.

Plants were not only a source of food, however. Accordingly, using a binomial system very similar to modern biological nomenclaturethe Swiss botanist Gaspard Bauhin designated plants by a generic and a specific name. The heterotrophic metabolism of food derived from plants and animals and the use of movement to obtain nutrients even if the organism itself remains in a relatively stationary position are characteristic of animal physiology.

He was the first to describe the inner malpighian layer of the skin, the papillae of the tonguethe outer part cortex of the cerebral area of the brainand the red blood cells.

Prior to Harvey, blood was supposed to be consumed by the body and produced anew rather than continually circulated. During this three-hour workshop, the teachers learned inexpensive and easy ways to observe photosynthesis using leaf discs of Dieffenbachia and how to demonstrate the role of pigments in capturing light energy and driving starch production in whole leaves.

At that time in Rome, however, it was considered improper to dissect human bodies, and, as a result, a detailed study of human anatomy was not possible. One of the most common forms of constraint involves the function of anatomical traits that differ in size.

Thus, SDPs should more accurately be called long-night plants; and LDPs should be called short-night plants to emphasize the key role played by darkness in photoperiodism.

Photoperiodism is responsible for the distribution of many plants worldwide. Despite that knowledge, however, glass lenses were not used extensively until around an anonymous person invented spectacles for the improvement of vision probably in the late s.


Aristotle was the first to show an understanding of an overall systematic taxonomy and to recognize units of different degrees within the system. Throughout the 16th century, interest in botanical study also existed in other countries, including the Netherlands, Switzerland, Italy, and France.

Taiz, Lincoln, and Eduardo Zeiger. It is perhaps surprising that the great developments in botany during the 16th century had no parallel in zoology.

Cell physiology

One of the most common issues in the interface between plants and humans is mowing the lawn. Thus, before explaining that a trait is an adaptation, it is necessary to identify whether it is also shown in ancestors and therefore may have evolved historically for different functions from those that it now serves.

Tutorials and Explanations I posted some instructions I developed for restringing Stannard Ursa Major Wind Chimes because I could find minimal specific help for this maintenance task.

Yersinia enterocoliticaPhotomicrograph of Gram stain of Yersinia enterocolitica, the causative agent of yersiniosis.The term "photoperiodism" was coined to describe a plant's ability to flower in response to changes in the photoperiod: the relative lengths of day and night.
