characteristic that distinguishes that have signaling and self sustaining processes from those that don’t. If an organism can perform certain functions such as movement‚ respiration‚ sensitivity‚ growth‚ reproduction‚ excretion‚ and nutrition‚ it is classified as a living organism. Life began from the basic building block of all living things‚ called cells. All organisms derived from single celled organisms. Cells are the basic building blocks of life and are found in all living things. For example‚ a group

mainly about the different species he saw on the Galapagos Islands. Each island had a different variation of birds. He noticed that the beak sizes of the finches were different on each island because of the size seeds they ate. Darwin noticed that organisms reproduce more offspring than can survive. Each individual offspring has unique characteristics that can be hereditable. Most of Darwin’s observations focused on the idea of natural adaptions. Darwin noticed that the body parts an animal used

Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting.

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

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.

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
