Organisms have complex and extraordinary tools for sensing their environments. These tools have been honed to enable them to efficiently navigate the world around them. As a result‚ each and every organism alive today is the product of natural selection. Over time‚ this acquired set of skills evolved into the five common senses; sight‚ smell‚ touch‚ hearing‚ and taste. Taste is one of the most valuable ways an organism can interact with its environment‚ since the ability to identify and process the

Cell(hours to reproduce)‚ Organism (hours to days to reproduce)‚ Population(up to thousands of years to reproduce)‚ Species (thousands to millions of years to reproduce) . Cells hold the replication for all major parts of organisms that become part of a population that are part of a species. All interconnect. 4).

Analytical Brief - Cloning Cloning is the process of creating copies of DNA‚ cells‚ or organisms‚ in other words‚ it is the “creation of an organism that is an exact copy of another” (What is Cloning?). An early embryo cell is separated in a petri dish and injected into a surrogate mother. Through cloning‚ scientists are able to make an exact genetic copy of a living organism. The clone and the original are identical in every way. Clones are able to function and interact with other living things

Microscopy Introduction What is life? What are the key factors that biologists have defined that apply to every single organism on the planet? In the 17th century‚ due to the amazing advancement of the microscope‚ biologists created a theory to differentiate the living from the non-living called the cell theory. One concept from the theory is that all living organisms are composed of one or more cells. The importance of studying cells is akin to the importance of studying life. By being able
Premium Bacteria Eukaryote Cell
All living things have evolved into three groups‚ or domains‚ of closely related organisms: Archaea‚ Bacteria‚ and Eukaryota. Archaea and Bacteria are small‚ simple cells surrounded by a membrane and a cell wall‚ with a circular strand of DNA containing their genes. They do not contain a nucleus or other internal structures that higher cells may have. These are called prokaryotes. Basically all the life you see today‚ including plants and animals‚ belongs to the third domain‚ Eukaryota. Eukaryotic

living things produce new organisms similar or identical to themselves. This has to happen because if a species were not able to reproduce‚ that species would quickly become extinct. Reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. The reproductive process‚ whether asexual or sexual always involves an exchange in hereditary material from the parents so that the new organism may also be able to

However‚ genetically modified organisms and products awaken apprehension regarding their affect on people’s health and the environment. There are therefore laws that regulate the use and exposure of these organisms. In the European Union there was a five-year moratorium on the approval of new genetically modified crops‚ which ended in May 2004 when type Bt-11 corn was
