.... wide surpassing the Himalayas in size. The mapping of the seafloor also revealed that these huge underwater mountain ranges have a deep trench which bisects the length of the ridges and in places is more than 2000 meters deep. Research into the heat flow from the ocean floor during the early 1960s revealed that the greatest heat flow was centered at the crests of these mid-oceanic ridges. Seismic studies show that the mid-oceanic ridges experience an elevated number of earthquakes. All these observations indicate intense geological activity at the mid-oceanic ridges. Geomagnetic Anom .....

.... of the . Heavy laughter or crying causes muscles in the upper lid to squeeze the lachrymal gland. This produces tears that flow too fast to be drained away. The lashes catch many flying particles that otherwise would enter the . As further protection, the lids automatically close when an object suddenly moves close to the . The eye is made of 3 coats, or tunics. The outermost coat consists of the cornea and the sclera. The middle coat contains the main blood supply to the eye and consists of the choroid, the ciliary body, and the Iris. The innermost layer is the retina. The Scl .....

.... come to understand the ways cells and genes work. As the information grows we will be able to get rid of genetic diseases and defects. “As geneticists have come to understand the ways in which genes operate, they have also become aware of the myriad ways in which the environment affects their ‘expression.’” In the future people will be able to decide what their child will look like and what kind of base intelligence the child will have, but they will not be able to decide the child’s fate. For the people who want to control what their children will look like, there is the poss .....

.... of life and industry. in the biosphere is essential in the processes of respiration and metabolism, the means by which animals derive the energy needed to sustain life. Furthermore, is the most abundant element at the surface of the Earth. In combined form it is found in ores, earth’s, rocks, and gemstones, as well as in all living organisms. is a gaseous chemical element in Group VA of the periodic table. The chemical symbol for atomic is O, its atomic number is 8, and its atomic weight is 15.9994. Elemental is known principally in the gaseous form as the diatomic molecule, whi .....

.... one part of a solution. The particles in a solution will not separate no matter how long the solution is allowed to stand under constant conditions. In a solution, one substance is usually considered to be dissolved, or broken down in another. The substance that is dissolved is called the solute. The substance that does the dissolving is the solvent. Not every substance dissolves in every other substances. A substance that dissolves in another substance is called soluble. Soluble means capable of being dissolved. A substance that does not dissolve is called insoluble. TYPES OF SOLUT .....

.... This period of tadpole life can be divided into three stages. The first stage, called “ premetamorphosis,” lasts about 50 days (Patent 54). The second stage, in which the hind legs grow, is called “prometamorphosis,” and lasts about 21 days. When the legs are about as long as the body, the third stage, which is called “ metamorphic climax,” and takes place very rapidly, begins. During this last stage, which lasts about a week, many great changes occur. They lungs complete their development, and the gills disappear. The skin gets thicker, nostrils form, and the tail is comple .....

.... would otherwise be stony, sandy masses habitable for life. Cell Structure and Function The tremendous variety of plant species is, in part, a reflection of the many distinct cell types that make up individual plants. Fundamental similarities exist among all these cell types, however, and these similarities indicate the common origin and the interrelationships of the different plant species. Each individual plant cell is at least partly self-sufficient, being isolated from its neighbors by a cell membrane, or plasma membrane, and a cell wall. The membrane and wall allow the individu .....

.... for fish tanks biological and mechanical. Biological is what I spoke about in the previous paragraph. Those bacteria grow best on objects besides gravel. That is why having plastic plants and other décor in the tank doesn’t just make the tank look nice but also give the bacteria a better place to grow. Mechanical filtration aids in biological filtration in two ways, the water is filtered through a medium that helps dissolve the ammonia and nitrites into smaller pieces easier for the bacteria to convert, and filter out bigger objects from the water such as excess food. Generally t .....

.... of stimulus information is more easily remembered, be it in randomized manner or meaningful. When are more errors made in remembering the stimuli, among these two types of stimuli used (CVC). Also, when a correct response is given, which was the type of stimuli (CVC) that caused this to occur. The design of this experiment on verbal learning has both within- subject and between-subject variables. The within-subject variables are the words (CVC) that are stored in the computer which are the default words to be used. The between-subject variables are the number of stimuli used and .....

.... and gastrozooid. The polyps are the parts that: capture prey, digest prey, and reproduce. The dactylozooids have cells called nematocysts(3). The nematocysts release a toxin(4) into anything that they come into contact with. The gastrozooids then attach to the dead/stunned victim, and spread over it. They digest it, and transfer food to the rest of the man-of-war. Last, the gonozooids create other polyps. The means by which the man-of-war reproduces, however, is not yet understood. The fish Nomeus gronvii lives among the tentacles of the man-of-war. This fish, which is eight centimet .....
