Summary 1 ' Section 1 ' 94-96
Vocabulary:
'Photosynthesis - is the process in which light energy is converted into chemical energy.
'Autotrophs - an organism that produces it's own nutrients from inorganic substances or from the environment instead of consuming other organisms.
'Heterotrophs - an organism that obtains organic good molecules by eating other organisms or their by products and that cannot synthesize organic compounds from inorganic materials.
' Cellular respiration - the process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide.
Summary:
Metabolism involves either using energy to build molecules or breaking down molecules in which energy is stored. Most autotrophs like plants are photosynthetic organisms. Some autotrophs use chemical energy from inorganic substances to make organic compounds. Prokaryotes found near deep-sea volcanic vents live in darkness. They however use chemicals flowing out of vents to get energy.
The chemical energy in Organic compounds can be transferred to other organic compounds or to organisms that consume food. Heterotrophs including humans get energy from good through the prices of cellular respiration. Cellular respiration releases energy in food to make ATP. This ATP provides cells ...
The current information technology mediums, such as the Internet pose exciting new opportunities for researchers and educators and, at the same time, present numerous questions and challenges. One of the current frustrations of many faculty includes their limited conceptual grasp of how these technologies can benefit themselves and their students....
The magnificent planet Mercury is the planet I have chosen to research. I this report I have explained all there is to know about Mercury and its aura. The Romans gave Mercury its name after the fleet-footed messenger of the gods because it seemed to move quicker than any other planet. It is the closest planet to the Sun, and second smallest planet...
If asked what light is, one could say that it's one of the most basic elements of our world and our universe as we perceive it. It is through sight that we receive 90% of our information. It is through the use of telescopes aiding the naked eye that we are aware of the heavenly bodies around us. It is through light that the energy from the sun is t...
Whether it be through intensified media attention, or due to the efforts of prominent scientists and other members of society, we have become increasingly aware of the have on the global environment. However, as Carl Sagan points out in 'Pulling the Plug on Mother Earth' awareness is not enough, nor is society's response to the catastrophic impli...
Mars is the fourth furthest away from the sun and is recognized by its reddish color. Mars is also very much like the Earth. " More than any other planet in the solar system, Mars has characteristics that make it an Earth-like world "(Grolier, 1992). One thing that is very similar to Earth is the rotation period. Mars rotation period is only thirty...
Frog is the common name for a species of amphibian that also includes toads. A very common question is 'whats the difference between and toads?' , the answer: none, except for the fact that toads lack the powerful legs that have. 'Where can and toads be found?', one might ask. They live in all parts of the world, except for Antarctica, but ar...
A few years ago if you were to ask someone about the possibilities of they would most likely say it was impossible. This attitude towards has been held into belief up until recently when scientists in Scotland cloned a sheep. And immediately after scientists in Oregon cloned a monkey (Fackelmann 276). The most major breakthroughs of the century i...
has been a reoccurring phenomenon for centuries. Man has only started to realize how much of the worlds weather is effected by it. The term refers to an irregular warming of the seas surface. During the last 40 years there have been 10 significant occurrences. Most affecting the coast of South America. Water temperatures increase along the...
Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels, such as crude oil and coal, discovered beneath the Earth?s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. However, we are no...
The engineering of deoxyribonucleic acid (DNA) is entirely new, yet genetics, as a field of science, has fascinated mankind for over 2,000 years. Man has always tried to bend nature around his will through selective breeding and other forms of practical genetics. Today, scientists have a greater understanding of genetics and its role in living orga...
As the millennium approaches we come closer and closer to what some say could mean the end of civilization as we know it. What is this great event that would have such an impact on the world that it could end civilization? The problem is a simple computer bug refereed to as the Y2K bug but its ramifications could be immense. This computer bug ha...
CLIMATE CHANGES: Climate changes have a key role to play when there is flooding because of the vast weather pattern changes. Firstly, Global Warming is one of the main causes of flooding due to changes in the climate. For example, due to the increasing levels of man-made greenhouse gasses in the atmosphere, causing the climate to get warmer it is...
Typically, the level of ocean water around the world is higher in the western Pacific and lower in the eastern, near the Western coast of South and North America. This is due primarily to the presence of easterly winds in the Pacific, which drag the surface water westward and raise the thermocline relatively all the way up to the surface in the eas...
There are 7 periods and 18 groups. The periodic table of the chemical elements (also periodic table of the elements or just the periodic table) is a tabular display of the chemical elements. Although precursors to this table exist, its invention is generally credited to Russian chemist Dmitri Mendeleev in 1869[1], who intended the table to illustra...
