Thus, he suggested, if a tall man marries a short woman, each should contribute half of the total heritage, and the resultant offspring should be intermediate between the two parents. Though animals traditionally drew the attention of many naturalists, the study of zoology remained underdeveloped during the middle ages, relying heavily on illustrated books of animals modeled on medieval bestiaries. Understand key science practices you can use to develop explanations and predictions of natural phenomena, which you will test and refine through laboratory investigations.

Of course, the actual process is much more complicated than just hitting print on a computer and waiting for an organ to pop out like a piece of paper. Researchers use animals closely related to humans in order to predict the effects of new drugs or surgical techniques on human subjects, taking advantage of evolutionary relationships that yield similar anatomies and physiologies in different organisms.

Relevance of science to other endeavors enables students to transfer skills gained from science instruction into their other school subjects and into their lives outside the classroom. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules. [7] Embedded within this membrane are a variety of other molecules that act as channels and pumps, moving different molecules into and out of the cell.

Physiology, which is closely related to anatomy, describes the mechanisms by which these different components perform. A fungus and a horse break down sugar to release energy using (more or less) the same enzymes. The following topics will be discussed in this course: mechanism of botanical action, indications and contraindications of botanicals, clinical problems, and a listing of botanicals.
