Cheetahs
Cheetahs For my vertebrate animal I chose the Cheetah. The Cheetah or Acinonyx Jubatus is an endangered species. They were once found throughout Africa and Asia, but are now only scattered throughout Eastern Africa and a small region of Southwestern Africa. Cheetahs are threatened by increasing loss of habitat, decline in prey, and increased poaching for fur trade. The Cheetah has a tawny coarse coat with round black spots or “tear stripes” from the corner of the eyes down to the sides of the no

Cloning
Cloning Cloning, the process of “Manipulating a cell from an animal so that it grows into an exact duplicate of that animal is the forbidden fruit of biology.” (Begley 54). The word “clone”, derived from the Greek word “Klon”, meaning twig or slip, refers to asexual reproduction. Also known as vegetative reproduction. Cloning became known to the public about 30 years ago. This idea of cloning about his time resulted in an experiment of the successful asexual reproduction. This experiment took pl
Cultural Evolution
Cultural Evolution
Cultural Evolution Cultural evolution began to occur during the most recent Ice Age, or within the last hundred or fifty thousand years. This is when the tools that\'s are used for sophisticated hunting are found; for example the spear thrower, the fully barbed harpoon, and the flint master tools that were used to make all the hunting tools. Cultural evolution took shape because man had the flexibility of mind to recognize inventions and to turn them into community property. The Ice Ages forced
Earthquakes
Earthquakes
Earthquakes I chose to research earthquakes and the prediction of earthquakes because I was curious as to how they work. In this paper, I will discus the history of earthquakes, the kinds and locations of earthquakes, earthquake effects, intensity scales, prediction, and my own predictions. An earthquake can be defined as vibrations produced in the earth\'s crust. Tectonic plates have friction between them which builds up as it tries to push away and suddenly ruptures and then rebounds. The vibr

Ecology
Ecology In the original Greek oikos means, house . So ecology is the study of the house the place where you live, or the environment which technically includes all those factors, both nonliving and living, that affect an organism. Ecology then is the study of the interactions of organisms in their environment includes both the living (biotic) and physical (abiotic) factors of the environment. It\'s also the science, which formulates and tests hypotheses about environment. Ecology is the relation
Environmental Air Pollution
Environmental Air Pollution
Environmental Air Pollution My views of the environment are rooted in my belief in creation. I do not believe that life on earth began spontaneously, nor do I believe that the earth is so delicately balanced. I don’t believe that the earth and its ecosystem are fragile. Many radical environmentalists do, they believe man can come along, all by themselves and change everything for worse. After hundreds of millions of years, they believe that we are the last two generations of human existence. And
Evidence For Evolution
Evidence For Evolution
Evidence For Evolution Since Darwin’s death in 1882, there have been many new evidences that support the theory of Evolution. The different types are the studies of fossils, the comparisons of organism structures and the vast knowledge of DNA. FOSSILS ARE ANY TRACES OF DEAD ORGANISMS One concept that is discussed is the concept of fossils. Examples of fossils are footprints of early humans, insects trapped in tree sap, tracks of dinosaurs and animals buried in tar. My thoughts are that fossils a

External Temps. On Crayfish And Mice Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell

Extinct Animals Research
Extinct Animals Research We have learned much about the Woolly Mammoth almost more than any other dinosaur that has been identified. Due to the fact that the Woolly Mammoth so closely resembles today\'s elephants, care for them would most probably require most of the same factors to keep it alive. Since the Woolly Mammoth has been extinct for 4000 years, it is difficult to tell exactly what they lived on, but we can hypothesize. The Woolly Mammoth lived during the Ice Age, so if alive today, it
Gene Manipulation
Gene Manipulation
Gene Manipulation Throughout time, man has always questioned science. Man has been curious about life, space, our bodies, and our existence. Man has gone as far as to the moon, and cloning. Everyday there are new developments being researched. Along with these developments come the people’s opinion. Many people question the positive outcomes and negative outcomes of procedures such as gene manipulation, cloning, in vitro fertilization and fetal tissue implants. To this day, scientists are resear

Geneology Genetic Engineering Two years ago Scottish scientists announced that they had successfully cloned a sheep. They named it dolly and it was an exact copy of the original sheep. Is cloning morally right? Is it ethical? Some people think that it is wrong and that it shouldn’t be practiced on any animal. In this report I will tell you about genetics, cloning and whether I think it is wrong or right. Genetics Is the study of a persons genes or ancestry. Genealogists can tell you where your a

Genetic Modified Food
Genetic Modified Food Genetic modification of organisms in general is a biotechnological process that forces genes to behave according to certain characteristics. Changing characteristics of organisms is based on changing their DNA (tech deoxyribonucleic acid; the acid which carries genetic information in a cell). It is being used for modifying genes in plants, animals or micro-organisms. It is being also used especially with food in order to improve the nutritious quality, make less use of chem
Greenhouse Effect 2
Greenhouse Effect 2
Greenhouse Effect 2 The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane whic

Human Evolution Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten

It revealed the idea that we, as humans, tend to be quite caught up in the idea of community; community between neighbors, co-workers, etc. seems to be something we strive for in our society. It seems that we have not integrated the land into our idea of community, and I feel that this

William Thomson (Lord Kelvin), referring to levitation as the problem of Mohamet’s coffin, had this to say: It will obably be impossible ever to observe this phenomenon, on account of the difficulty of getting a magnet strong enough, and a diamagnetic substance sufficiently light, as the [magnetic] forces are excessively feeble.

We have found that our pellet in particular is roughly 4.5 cm long, 2.5 cm wide, and exactly 5.278 grams in weight. Compared to the other pellets researched, ours was essentially the same from the outside, but the findings inside were quite unique. While searching through the owl pellet, we discovered two, fully grown vole sk

Pesticides Pesticides are chemicals that are used to destroy pests. In the agricultural industry, pesticides are classified into two categories, carcinogenic and non-carcinogenic. A carcinogenic pesticide is a substance or agent producing or inciting cancer. Conversely, a non-carcinogenic pesticide is substance that does not produce or incite cancer. Most agricultural pesticides were registered in the 1950’s, with no standard regulations. The most considerable standard prior to the amendments of

Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of sodium, potassium and ammonium are insoluble in water. Tertiary sodium phosphate is valu

First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells. These three facts are referred to as the cell theory. All cells can be categorized into two basic cell types. They are prokaryotic and eukaryotic. To distinguish where cel

His muscles were taut; he swooped through the air more like an eagle than a Greylag gander. The only problem was, it was not for her that he then landed in a flurry of quacks and wingbeats, or for her that he dashed off surprise attacks on his fellows. It was, rather, for another - for her preening rival across the Bavarian lake. Poor goose. Will she mate

Based on this time frame it is believed that an African Hominoid lineage was present shortly before that time, approximately 10 myp, which contained the common ancestor to both the chimpanzee and human. The split into proto-chimpanzee and proto-human occurred during the last million years of the Miocene epoch. (Changeux and Chavaillon pg. 61). The

However, the idea that species mutate over time has been around for a long time in one form or another. Therefore, by Darwin’s time the idea that species change from one type into another was by no means new, but was rejected by most because the proponents of evolution could not come up with a satisfactory mechanism that woul
