living organisms‚ the solvent (water) would have net movement across a selective permeable membrane. Osmosis only occurs when a membrane such as that of a cell is permeable to water molecules but not to specific solutes (Tortora & Derrickson 2014). Certain simple molecules such as oxygen‚ water and carbon dioxide can travel across the cell membrane by osmosis‚ a passive process similar to other forms of diffusion (Hill 2007). Not merely is it vital to several processes in living organisms‚ it also

| Gram Negative Unknown | Biology 3444-006 | | Lena Wallace | 11/7/2011 | | Abstract: The purpose of this lab was to identify an unknown bacteria culture using differential tests. The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li

GMO stands for Genetically Modified Organisms. This means they undergo a certain forced process where they are introduced to bacteria and viruses to receive different traits to resist diseases or the tolerance of pesticides. GMO crops have been in the news for a very long time and it’s safe to say there are some pretty heated arguments about the topic. These foods that have been introduced to GMO have been tested with the World Health Organization and humans are safe to consume them. All living

All organisms must have adaptations to survive. The adaptations that organisms develop help them to survive in their environments and then are passed down through reproduction. The genes are passed to future generations and adaptations continue to occur over long periods of time. Nature Works tells us‚” animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.” There are three types of adaptations that can occur: morphological

Genetically Engineered Foods or Organisms Genetically Engineered Foods or Organisms Biological Basis Genetically modified crops (GMCs) are plants having DNA altered through genetic engineering techniques. The goal is to introduce a new desirable trait to a plant that does ordinarily occur in the species. Desirable characteristics include resistance to environmental conditions‚ resistance to diseases and specific pests and production of a particular nutrient. Genetic

Genetically Modified Organisms The Human genome is known to be the sequencing of about twenty thousand five hundred thousand genes that make up our human DNA‚ or the building block that tells our cells what to do. The government created project that is named the Human Genome Project started in 1990’s‚ and is trying to pick apart at the three billion chemical base pairs in a DNA strand. The full set of the information present in the form of the genes in living organism then forms its genome

Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 2.2 Identify

Unknown Bacteria Lab Report Introduction The purpose to this lab was to identify an unknown bacteria from a mixed culture provided to us by our instructor. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown organism in question and how the bacteria function. Over a two week period‚ eight prepared types of test media were provided to identify

Are GMO’s the Future of Food? To some‚ “Genetically Modified” is synonymous with “dangerous” and “unnatural” to others Genetically Modified Organisms can mean the difference between eating or starving‚ and can mean saving thousands of dollars in crop losses. GMO’s can help farmers grow more food on less land and can help farmers in the developing world grow a sustenance crop to support and feed their families. Those who view GMO’s as a danger to themselves and their children usually don’t fully
