are produced in medicines to help fight harmful infections and they benefit the taste of food. Microbes‚ or “microscopic organisms‚” are tiny forms of life that surround us and are too small to be seen with your eyes. To be able to see microbes we need to use a microscope. Bacteria are classified and identified to distinguish one organism from another and to group similar organisms by criteria of interest to microbiologists or other scientists. The most important level of this type of classification

is the biological process by which new individual organisms are produced. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. During reproduction‚ new offspring individual organisms are produced from their parents. How reproduction works? Good question! It is said that reproduction can either be asexual or sexual. First of all‚ when an organism reproduces asexually‚ that organism creates a genetically similar or identical copy of

Causes and Spread of Infection 1.1Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 1.2 Identify common illnesses

This is a mixture of medicine and biology‚ which analyses the effects of a drug on a cell‚ tissue‚ organ or organism. A pathologist is what Sir Howard Florey did‚ in studying diseases‚ learning about it and diagnosing the disease. His best-known work dates from his collaboration with chain‚ which began in 1938 when they conducted investigation of the properties

Definitions: Species: A group of organisms that interbreed and produce fertile offspring e.g. horses and donkeys Population: A group of organisms of the same species living in the same area at the same time‚ and which are capable of interbreeding Biodiversity: The amount of biological or living diversity per unit area. It includes the concepts of species diversity‚ habitat diversity and genetic diversity. Species diversity: Both the range and number of organisms found in a single place or habitat

study of organisms. In preparing for two basic observations‚ a wet mount and a simple stain‚ living microorganisms can be seen clearer through a simple stain and by using a drop of water‚ movements of microorganisms are varied. A smear is when a spreading of bacteria is made on a slide for viewing. A simple stain is when a method of observation of a living organism is smeared on a slide with one stain during a procedure. A wet mount is where a research method of an organism or organisms is placed

it could be an animal‚ plants‚ or any other organisms and factors such as the weather‚ etc. evolution is the change over time of behavior‚ physiological or anatomical of a species. When Evolution happens it happens to the entire population not only 1 or 2 individual; evolution is the change in genes over time. The theory of evolution explains how species change over generations‚ why organisms are well-suited to their environment‚ and why some organisms resemble each other. Evolution is called a theory

Generally‚ progress is the process of improving over time‚ but as it relates to science‚ progress is the idea that science increases its problem-solving ability through the application of some scientific method. Overtime‚ science has indeed made tremendous progress through various analytical methods; one of the most controversial beings‚ ‘bioengineering’. Bioengineering is believed to be merely cloning‚ but bioengineering is specifically the application of sciences and engineering techniques that

Scientific Method: 1) What is the scientific method? The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. 2) What are the steps of the scientific method? Ask a Question‚ Do Research‚ Hypothesis‚ Test Your Hypothesis by Doing an Experiment‚ Analyze Your Data‚ Draw a Conclusion‚ And Communicate Your Results. 3) Why do scientists use the scientific method? What are the benefits of using it? Scientists use this method to have a formula

Biosphere MODULE - 5 The domain of Life on the Earth 14 Notes BIOSPHERE We know that our earth is the only planet where life is found. That is why this planet is also known as living planet or ‘sphare’ of ‘life’. This sphere contains those qualities atmosphere‚ lithosphere and hydrosphere. They all enable the life to exist on this planet. But do you know this is a very small portion of the earth where life exists. Beyond this narrow space of the earth‚ there is no life forms found.
