Analysis of the oldest sedimentary rocks provides evidence for the origin of life • Identify the relationship between the conditions on early Earth and the origin of organic molecules Notes THE AGE OF THE EARTH - based on geological‚ magnetic‚ radiographic and paleontological studies: aged 4.5 billion years - Hadean eon: formation of earth from gaseous cloud to solid body. Heavy molten iron sank down and became the core‚ lighter rock came to surface = crust

Anything which we eat to live is called food. Food contains energy. The food (or energy) can be transferred from one organism to the other through food chains. The starting point of a food chain is a category of organisms called producers. Producers are‚ in fact‚ plants. So‚ we can say that all the food chains begin with a green plant (or grass) which is the original source of all food. Let us take an example to understand the meaning of food chain. Suppose there is a field having a lot of green

Microbiology nutrition and growth Microbiology is a branch of science that deals with the study of small micro-organism that cannot be seen through naked eyes but only through the use of a microscope. Some of the Micro-organism in the environment include; bacteria‚ viruses and fungi to mention but a few. Whereas some Micro-organisms are associated with causing of diseases others are known for destroying the balance in the ecosystem. However‚ this is not always the case

natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy. * The cell is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing (except virus‚ which consists only from DNA/RNA covered by protein and lipids)‚ and is often called the building block of life. Organisms can be classified as unicellular (consisting of a single

a lot of controversy on whether or not a virus is a living or non-living organism. The dictionary.com definition for life is‚ “the condition that distinguishes organisms from inorganic objects and dead organisms‚ being manifested by growth through metabolism‚ reproduction‚ and the power of adaptation to environment through changes originating internally.” Viruses have characteristics of both living and non-living organisms‚ for example‚ a living characteristic includes reproduction. A non-living

Genetic Manipulation Report-Daisy the Cow Humans manipulate genetic transfer when cloning animals and modifying expressions of a gene to achieve the desirable traits‚ alleles or phenotype by changing the DNA sequence of an organism (Genetic Manipulation). This allows the organism to reproduce offspring with the specific gene and allows them to pass on those desired genes. An example of this is Daisy the cow. Daisy was cloned and genetically modified so that milk will not produce that contains the

life because for wise men living is something totally different to staying alive. For them‚ life’s just too short to live. All the organisms perform some basic functions to keep themselves alive. The basic functions performed by living organisms to maintain their life on this earth are called life processes. The basic life processes common to all the living organisms are: Nutrition and Respiration; Transport and Excretion; Control and Coordination (Response to stimuli); Growth; Movement and Reproduction

Bacteria is a organism that is present in most habitats‚ as well as human bodies and other living organisms such as plants and animals. Bacteria multiplies by its self to progress and spread. Unlike other infections such as viruses‚ fungi or parasites bacteria is not always harmful in fact in many cases bacteria can be useful to the living organisms‚habitats or plants that it infects. Viruses are a small infectious agent that can only multiply inside the cells of living organisms although unlike
