Endangered Manatee

... death. Marine biologists have been unable to find the cause of these deaths. They suspect that the Red Tide off of the coast of southwest Florida has some connection with these mysterious deaths. A red tide is a bloom of flagellates which are deadly to marine life, but cause no harm to the human population. Another possible cause is a virus that is unknown to scientists. Many people believe that this problem will eventually stop an the manatee population will flourish, but others are rather pessimistic. Ecological Problem: The manat ...

What Are The Major Components Of Biological Membranes And How Do They Contribute To Membrane Function?.

... Overall the biological membrane is an extensive, self-sealing, fluid, asymmetric, selectively permeable, compartmental barrier essential for a cell or organelles correct functioning, and thus its survival. Introduction. Biological membranes surround all living cells, and may also be found surrounding many of an eukaryotes organelles. The membrane is essential to the survival of a cell due to its diverse range of functions. There are general functions common to all membranes such as control of permeability, and then there are spec ...

Fluoride

... in plaque break down sugars and carbohydrates from the diet. Repeated acid attacks break down the tooth, which causes cavities. Fluoride also acts to repair areas in which acid attacks have already begun. The remineralization effect of fluoride is important because it reverses the early decay process as well as creating a tooth surface that is more resistant to decay. Community water fluoridation is the adjustment of the amount of the beneficial trace element fluoride found in water to provide for the proper protection of teeth. Fluoridation ...

Aandp Kidney Problems

... are then reabsorbed into the bloodstream. The remaining waste material is collected as urine and excreted from the body. As blood enters into the renal artery it travels through smaller vessels on its route to the cortex of the kidney. Once in the cores the vessels become even smaller forming capillary balls called Glomeruli. The Glomeruli pick up certain substances that travel through the Glomeruli capillary wall and enter the proximal kidney tubules, creating an ultra filtration systems, which eventually becomes urine. Substances t ...

Computers That Mimic The Human Mind

... to create computers and software that mimic the human mind, then Eliminative Materialism is a sound solution to the mind-body problem. In order to examine if computers actually do mimic the human mind then we must first look at the capabilities of the human mind. If one looks closely at the capabilities of the human mind and compares them to the most recent technological advances, then it would be obvious that computers and software are beginning to mimic even the most advanced mental states. In the future, computers will be able to do an ...

Global Warming And The Greenhouse Effect

... of time. Without the effect, the surface of the earth would be -20 degrees Celsius, oceans would have frozen, and there would be no life on earth. The Washington Post has reported that the earth is warmer than it has been in 1,200 years.2 Recently, the summer of 1999 set records for heat in much of the United States. The average world temperature has increased one degree Fahrenheit over the last 120 years, making the world hotter than it has been in 100,000 years. From the beginning of the industrial revolution, concentrations of ca ...

Cloning 2

... vocabulary and discussion of technical concepts within these journal articles make good sense to those with strong science backgrounds, but not to the lay audience. On the other hand, the reports constructed from existing information are broadly based, pulling information from several sources and adapting it for target audiences. Such articles tackle general biomedical issues and convey the information to an audience that, for the most part, lack a high level of scientific knowledge. To make the information more understandable for the tar ...

... forearm, hip, wrist, finger, and other bones, as well as the lungs or gills of the early tetrapod fossils. This information is critical in understanding the history and the process of growth and change. It aids in learning about human evolution. Background: Tetrapods are creatures with four limbs, hips, shoulders, fingers, and toes, which developed sometime after lobe-finned fish, and before the first fully terrestrial vertebrates. The earliest tetrapod known is Acanthostega. It is also considered the most primitive tetrapod. It is very clos ...

Taking The Pill Depression And

... as a way out instead of a legitimate medicine. But the people that feel this way, often have not had any personal experience with this illness. The physical basis of depression involves neurotransmitters in the brain. Neurotransmitters are chemicals that carry messages from one nerve cell to another. Nerve cells do not touch. There are microscopic gaps between them called synapses. For a nerve impulse to travel from one nerve cell to another, the sending cell releases a tiny amount of one of the neurotransmitters, which transmits ...

... of the world’s most horrifying man-made substances; however, when this phenomenon was first tested it had no effects on the lab animals, therefore its study was discontinued. LSD’s study was revived in 1943, when research indicated it could potentially be used as treatment for schizophrenia, due to its similarity in structure to Nicatamide, a chemical found in the human brain, which directly affects the experiences of a Schizophrenic (DEA,1). On April 16, 1943, while Dr. Hofmann was measuring a fresh quantity of LSD, he accidenta ...
