MULTICELLULAR ORGANISMS The complex multicellular animals and plants perform many different activities in order to exist. More energy is invested in all organisms for their accumulation and distribution of food‚ release of waste matters‚ movement‚ reproduction‚ and coordination of these activities. The different organisms have specialized tissues‚ organs and organ systems that work together for the good of the organisms. Thus the well-being of the whole organism depends on the integration

Diversity in Living Organisms (Science) |Close X | |[pic] Classification And Evolution Classification refers to the identification‚ naming‚ and grouping of organisms into a formal system based on similarities in their internal and external structure or evolutionary history. It determines the methods of organizing diversity of life on earth. Therefore‚ classification helps in understanding millions of life forms in detail. Who started the classification of organisms? Let us explore the history of

Synopsis – Grade 9 Science Term II Chapter 1: Atoms and Molecules Law of conservation of mass: Mass can neither be created nor can it be destroyed in a chemical reaction. Law of constant proportion: A chemical substance always contains the same elements in a fixed proportion by mass‚ irrespective of the source of compound. Atom: The smallest particle which is the building block of matter. The symbol of the element is made from one or two letters of the English

Disease is any condition that adversely affects the function of any part of a living thing. Health is the wellbeing of the organism. All our body functions‚ which are under the control of our genes‚ work together to maintain health. Difficulties in determining health and disease: Disease can cover a wide range of conditions including minor conditions‚ such as a cut finger or an ant bite‚ as well as the more obvious diseases like cancers. Health varies on a daily basis and is not just the absence

An Argument for Evolution Tori Brotherton Lynchburg College Evolution is defined as the change in frequency of genetically determined characteristics within a population over time. There are three key points to consider when referring to this definition. First‚ evolution only occurs in populations‚ which are defined as groups os organisms of the same species that are able to interbreed and are genetically similar. Second‚ genes determine the characteristics displayed by organisms. Third‚ the

READING MATERIAL 1. Explain the three hypotheses for the recent changes in the toxicity of venom in different species of rattlesnakes found in the United States. - Interbreeding between snakes with different venom profiles. - Geographic distribution (genes shifted eastward) - Convolution - Old rattlesnakes have high concentration of toxic. 2. What is an “evolutionary arms race”? Describe how this applies to one of the hypotheses suggested to explain toxicity of venom in rattlers
