The Characteristics of Life There are many properties or the signs of life that the living organisms have. In the book of biology of Mrtinez and Nazareno‚ there are nine characteristics of life just said and those are : a. Living things are highly organized and contain many complex chemical substances ; b. Living things are made up of one or more cells‚ which are the smallest unit that can be said to be alive; c. Living things use energy; d. Living thins have definite

a medical lab is to determine the identity of pathogenic bacteria. It is important to determine the specific type of bacterium causing disease so the physician is able to correctly treat the patients. The structure of bacteria plays a crucial role of what antibiotics works and which do not. The chemical reaction of the bacteria is also important. Most antibiotics alter or inhibit protein structure‚ inhibit transcription‚ inhibit translation‚ affect cell membrane structure‚ or alter cell-wall synthesis

Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

Lab 12: Meiosis kimberleigh Lewis Biology 1408-63400 Consider the Concepts Experiment: 1. A common misconception about meiosis appears when students identify which of the two divisions converts a diploid cell into two haploid cells. Meiosis I is the division immediately following DNA replication and replication does not occur again before meiosis II. However‚ meiosis I is the "reduction" division when a diploid cell forms two haploid cells. If the DNA duplicated before meiosis I‚ how

DEFINITIONS * Biology is a 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

Biology textbook- pg. 80 3) Distinguish between the autotrophic and heterotrophic nature of plants and animals. Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there
