Scientific Classification in Biology
Classification in biology, is the identification, naming, and grouping of
organisms into a formal system. The vast numbers of living forms are named
and arranged in an orderly manner so that biologists all over the world can
be sure they know the exact organism that is being examined and discussed.
Groups of organisms must be defined by the selection of important
characteristics, or shared traits, that make the members of each group
similar to one another and unlike members of other groups. Modern
classification schemes also attempt to place groups into categories that
will reflect an understanding of the evolutionary processes underlying the
similarities and differences among organisms. Such categories form a kind
of pyramid, or hierarchy, in which the different levels should represent
the different degrees of evolutionary relationship. The hierarchy extends
upward from several million species, each made up of individual organisms
that are closely related, to a few kingdoms, each containing large
assemblages of organisms, many of which are only distantly related.
Carolus Linnaeus is probably the single most dominant figure in systematic
classification. Born in 1707, he had a mind that was orderly to the extreme.
People sent him plants from all over the world, and he would devise a way
to relate them. At the age of thirty-two he was the author of fourteen
botanical works. His two most famous were Genera Plantarum, developing an
artificial sexual system, and Species Plantarum, a famous work where he
named and classified every plant known to him, and for the first time gave
each plant a binomial. This binomial system was a vast improvement over
some of the old descri...

...ly and structurally too dissimilar to the species
categorized above to fit into that scheme of taxonomy.
Although this system is complex and intricate at times, its
universality makes it a necessity. With out the system presently in use the
world would be years and years behind in their task to name all of the
living organisms on earth. This system is great but it is always possible
that some new finding could cause the system to evolve to become more
inclusive. This system is by no means set in stone, and Linnaeus would
probably be astounded to see the way that it has evolved since his original
system.

It was while he was sitting there, facing the southeast, that he noticed how the four windows along the south wall of the kiva had a particular relationship to this late autumn position of the sun” (Silko, 238).

Biology literally means "the study of life". Biology is such a broad field, covering the minute workings of chemical machines inside our cells, to broad scale concepts of ecosystems and global climate change. Biologists study intimate details of the human brain, the composition of our genes, and even the functioning of our reproductive system. Biologists recently all but completed the deciphering of the human genome, the sequence of deoxyribonucleic acid (DNA) bases that may determine much of our innate capabilities and predispositions to certain forms of behavior and illnesses. DNA sequences have played major roles in criminal cases (O.J. Simpson, as well as the reversal of death penalties for many wrongfully convicted individuals), as well as the impeachment of President Clinton (the stain at least did not lie). We are bombarded with headlines about possible health risks from favorite foods (Chinese, Mexican, hamburgers, etc.) as well as the potential benefits of eating other foods such as cooked tomatoes. Informercials tout the benefits of metabolism-adjusting drugs for weight loss. Many Americans are turning to herbal remedies to ease arthritis pain, improve memory, as well as improve our moods. Can a biology book give you the answers to these questions? No, but it will enable you learn how to sift through the biases of investigators, the press, and others in a quest to critically evaluate the question. To be honest, five years after you are through with this class it is doubtful you would remember all the details of meatbolism. However, you will know where to look and maybe a little about the process of science that will allow you to make an informed decision. Will you be a scientist? Yes, in a way. You may not be formally trained as a science major, but you can think critically, solve problems, and have some idea about what science can and cannoit do. I hope you will be able to tell the shoe from the shinola.
Morgan played on Danny, was, they gave gave him a bud in the beginning. That day, he told his plant a joke and watered it. The next day, his plant had branched out! He did the exact same thing thing he had done the day before. Watered it and told it a joke. When he woke up the next morning it got even larger. Danny was getting more and more excited each day the plant grew more, which meant Danny’s mom’s trick was working! By the third night, Danny’s mom suggested they should put the plant outside. He ran outside the next morning only to see that his plant had grown into a flower bush! He took plenty pictures to show his class. After he had gone to school and showed the pictures to his classmates, Mr.Morgan took the class outside. Danny saw all his plant, he also saw the ones he had on each day! To his surprise, his mom popped out from behind the bush. They told him about their plan. Danny was not mad at his mom, and he still got the last laugh. He also got the new music tape that he was owed. Danny should’ve done some research, because the article “Probing Question: Does talking to plants help them grow?” states that “ people would have to speak to their plants for at least several hours a day to enhance photosynthesis enough to influence plant growth”. He could have figured out his was all a
