different types of habitats‚ such as disturbed and less disturbed hillsides? Explain. Abiotic factors are factors resulting from the activities of a living thing or any living component in an environment‚ such as the actions of an organism affecting the life of another organism. These factors include humans‚ animals (cows)‚ insects‚ plants shading other plants‚ grazing. For example‚ grazing has been a common and‚ in some cases‚ intense disturbance in many plant communities. When animals graze on plants

B) Living things exhibit complex but ordered organization. C) Organisms respond to environmental stimuli. D) Organisms take in energy and use it to perform all of life’s activities. E) Organisms reproduce their own kind. 3) What are the two main processes that ecosystems depend upon? nutrient cycling and energy flow

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

is a field of applied biology that involves the use of living organisms and bioprocesses in engineering‚ technology‚ medicine and other fields requiring bioproducts. The concept encompasses a wide range of procedures for modifying living organisms according to human purposes. For thousands of years‚ humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding‚ organisms with desirable characteristics are mated to produce offspring with

living plants‚ organisms‚ and animals. There are for main components in an ecosystem. The relationship of these four components makes it possible for each component to pass energy and use the food chain to survive and flourish. Elements and compounds are basically a required food source for plants. Plants utilize the sun and photosynthesis to harness energy and are the primary producers of new energy into an ecosystem. Consumers are a source of food that feeds on other organisms. This could be

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.

process of mitosis and meiosis both important to a living organism? Mitosis and meiosis are important‚ because mitosis is a type of sexual reproduction which enables a cell to reproduce two new genetically identical daughter cells from a single parent cell (Pruitt and Underwood‚ 2006). During this process mitosis has the function of permitting cells to replace ones that are worn out‚ damaged‚ or need to be replicated for single cells organism. Where mitosis is asexual cellular reproduction‚ meiosis

Andre’ Bertrand Sean Comeaux Biology 1 1st October 2011 Animal Cells Every once living thing is composed of cells. Cells are small organisms that control everything in living things. When an organism is made of one or more cells it is called a multi cellular organism. The first person to discover cells was Richard Hooke. The cells that he saw were the dead cells of cork. When he first saw them they reminded him of the cells that nearby monks lived in. there are many different parts
