[pic] Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla‚ families and genera have some species that live in the sea and others that live on land‚ marine biology classifies species based on the environment rather than on taxonomy. Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment‚ and biology is the study of the organisms

AP/IB 11 Biology Origins of Life on Earth There are multiple theories as to how life began on earth‚ beginning with the findings of various revolutionary scientists. This paper will discuss various scientists’ theories and experiments as they strove to discover how life began‚ and the processes that might have occurred in order to develop and create the world we are now familiar with today. Recent discovered functions of RNA have suggested that RNA provides a crucial framework in the evolution

“UNSAFE DRINKING WATER” An adequate supply of safe drinking water is one of the major prerequisites for a healthy life‚ but waterborne disease is still a major cause of death in many parts of the world‚ particularly in children‚ and it is also a significant economic constraint in many subsistence economies. The basis on which drinking water safety is judged is national standards or international guidelines. The most important of these are the WHO Guidelines for Drinking Water Quality. The quality

BIO 330 Exam 1 Lecture 1 * The oldest shell middens from South Africa have been dated in 140‚000 years old * Modern science is based on the application of the scientific method Lecture 2 * In the middle‚ ascending mantle material makes a mid ocean ridge * In areas where two continents are pushing against each other‚ one sinks underneath the other producing subduction zones that create deep trenches * Solid water (ice) displaces more volume than liquid water‚ therefore it floats

extensive impact on the interdependent biosphere because biodiversity is directly intertwined with the nonliving components of the Earth (Mittermeier et al. 2002). Aquatic ecosystems have a large biodiversity of species such as phytoplankton‚ cyanobacteria‚ zooplankton‚ insects‚ fish‚ birds‚ and mammals (Reece et al. 2010). Each species makes a unique contribution to the function of the ecosystem‚ and adding or removing species from an ecosystem can have a measurable impact unless lost contributions

PLASTIDS Plastids are large cytoplasmic organelles. Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis‚ and the types of pigments present can change or determine the cell’s colour. The term plastid was derived from the Greek word plastikas meaning formed or moulded. This term was coined by Schimper in 1885. In plants

Biology Midterm Outline Topics: * Topic One: Chemistry of Living Things (p2-4) * Topic Two: The Cell (p5-6) * Topic Seven: Evolution (p23-27) * Topic Ten: State Labs (37-40) Topic One: Chemistry of Living Things I. All living things must maintain homeostasis in order to stay alive. A) Homeostasis: A balanced state in an organism’s body. B) Failure to maintain homeostasis results in disease or death. C) Homeostasis is often maintained using feedback mechanisms. 1. Feedback mechanisms

Astronomy Research and the Search of Extraterrestrial Life Paper Megan Lade University of Phoenix (Online Campus) Christopher Conner All life on this planet is linked to the geology of Earth‚ and vice versa – we (all organisms) are supposed to be living in a symbiotic relationship with our world. When Earth was developing deep within its curst began the first traces of raw materials and minerals that would fuel life for many years to come. We adapt and change to our ever
