Effect of ions on living organisms (24 marks) An ion is a charged atom or molecule. This is because it does not have an equal amount of protons and electrons‚ therefore giving the atom an overall charge. An example of an ion is ‚ this is sodium and the plus sign represents an overall positive charge. Ions are very important to living organisms as they are essential for life‚ they play an important role within the cell allowing mechanisms within the living organisms such as respiration‚ to take

Discuss the Role of Hydrogen Bonding in living Organisms A hydrogen bond is an intermolecular bond and is formed when a charged part of a molecule having polar covalent bonds‚ forms an electrostatic attraction with a molecule of opposite charge‚ generally with fluorine‚ oxygen and nitrogen. Molecules having non polar covalent bonds do not form hydrogen bonds. Hydrogen bonds are classified as weak bonds as they are easily and rapidly formed and broken‚ however the cumulative effects of large

Genetically modified organisms or as most of us know them by GMOs. These are organisms where a gene is purposely changed or added artificially to make it more appealing. Humans have been genetically enhancing anything we can. Many people are for GMOs while others are against it. An estimated 70% of all of our food supply contain at least one genetically modified organism. Therefor if you were against it there is really no way of running away from them. I think GMOs do more good then harm. Selective

Amanda Lab Report 1 Microbiology Laboratory Title – Differentiating Organisms using the Gram Stain Introduction The experiment conducted was based upon the known attributes of two different groups of bacteria‚ those that are gram positive‚ and those that are gram negative. Using a specific staining procedure‚ it is possible to differentiate the two types under a microscope The gram stain method of differentiation is possible because of differences in the cell membrane between the two categories

A GMO is a “genetically modified organism: an organism or microorganism whose genetic material has been altered by means of genetic engineering‚” (Dictionary.com‚ web). There is nothing wrong with GMO’s‚ they simply allow for better taste‚ better quality‚ and bigger proportions in our food. In today’s society everyone wants the next bigger and better thing‚ which is what GMO’s allow. However‚ for some reason people seem to prefer “organic” selections

Webster’s definition of “GMO” states “A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering techniques.” The simple version of that definition is basically that people‚ for whatever reason‚ decided to modify crops or organisms to fit certain qualifications and characteristics of their choosing. The gene introduced into the organism is exaggerated to fit the desire of the creator. For example

Why is water important for living organisms? Water is very important in all living organisms‚ it is vital for many different things. Around 70% of our body weight is due to water. The quantity is high in organs such as lungs and brain and fluids such as blood‚ lymph‚ saliva and secretions by the organs of the digestive system. First of all water is vital in the regulation of body temperature to depending on the temperature mammals will alter the amount they sweat. If they are to warm the amount

Unknown Organism Report Unknown Organism # 4 Klebsiella pneumonia Klebsiella pneumonia has a rod gram stain with the agar slant cultural characteristics being slimy‚ white‚ somewhat translucent‚ raised growth. It is small gram-negative coccobacilli that can cause lobar pneumonia. The litmus milk reaction is acid‚ gas‚ and curd with a variable reaction. Klebsiella can grow either in the presence or absence of oxygen because of its nature of being a facultative anaerobe. Oxygen is a preferred energy

The Process of Osmosis and its Importance to Living Organisms. Osmosis is the diffusion of water through a semipermeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only to diffusion of water and the direction of movement is from the area of higher concentration to the area of lower concentration. This migration of water from a region of higher concentration to a region of lower concentration is spontaneous and although water molecules move in both directions

What’s better‚ mass produced or crafted beer? According to (http://www.brewersassociation.org/pages/business-tools/craft-brewing-statistics/craft-brewer-defined) a craft brewer is “small‚ independent and traditional”. They have to produce less than six million barrels to be considered a craft brewery. Also from a financial point there is a difference to a mass producing beer brewery‚ an alcoholic industry can only have a maximum of 25% of the brewery. If they own more than this they are considered
