The Effects Of Dioxide On Carbon Dioxide Flux Rate

This lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. Oxygen and carbon dioxide are gases that are vital to all organisms, whether it is given or released through that organism. Both plants and animals use oxygen and carbon dioxide for cellular respiration, giving off carbon dioxide as a waste product. This lab is an example of cellular respiration in both plants and animals. The change in the carbon dioxide levels will be

•For each of your two reactions, most of the reactants and products can be difficult to see, and concentration can be difficult to measure without the proper laboratory equipment. Therefore, it is recommended that the volume of carbon dioxide gas produced over a given amount of time be used to help qualitatively compare the reaction rates of each trial. If you have another way you would like to compare rates of this reaction, feel free to explain it thoroughly in your written lab procedure.

-In an enclosed environment measuring levels of CO2 and O2 could help to determine rate of photosynthesis. The NET photosynthesis is equal to photosynthesis-respiration to account for what happens during the night.

The Purpose of this experiment was to determine the importance of cellular respiration in the processes of Life. The objective of this experiment was to determine the rate of cellular respiration and how the presence of carbohydrates and pollutants will affect it. Our hypothesis was that an organism has larger rate of Cellular Respiration with the source of Carbohydrates as compared to the one that is without the Carbohydrates source and vice versa in

Microbes are bacteria, archaea and eukaryotes. The earth was formed 4.6 million years ago. And a few million years later, by 3.5 billion years ago, earth was already inhabited by a diversity of organisms. The earliest organism is Prokaryotes and within the next billion years, two distinct groups of prokaryotes called bacteria and archaea diverged. Eukaryotes cell evolved from a prokaryotes community, a host cell containing even smaller prokaryotes .The microbial world accounted for all known life forms for nearly 50 to 90% of Earth's history. We are still researching microbial organisms today in marine environment, extreme environments. A microbial observatory is an NSF-funded project dedicated to the discovery and characterization of novel microorganisms and microbial communities of diverse

The ten most abundant bacterial families detected in our study were Koribacteraceae (Acidobacteria), Acidobacteriaceae (Acidobacteria), Sphingobacteriaceae (Bacteroidetes), Geobacteraceae (proteobacteria), Auto67-4W (Pedosphaerae), Acetobacteraceae (proteobacteria),

It is a gram-positive soil organism. Arthrobacter sp. will grow and divide in nutrient- rich soil. They are rod- shaped, tan to yellow in color, and smooth and glossy in colonies. Under normal conditions, they can grow rapidly and divide once every 2-3 hours (Poxleitner, M, et al). This bacterium is tolerant to multiple metals and it is extremely resistant to elevated concentrations of chromate It is also used in the number of carbon sources for growth including glucose, fructose, lactate, succinate, malate and hydrocarbons (Nakatsu, C, et al). In the SEA Phage Project, Arthrobacter sp. would be helping to create more bacteriophage to continue on completing the main objective of this

Prokaryotes are ubiquitous, successfully adapting to diverse environments as well as developing symbiotic relationships with host organisms (Lengeler, Drews, & Schlegel, 1999). Prokaryotes may have both autotrophic and heterotrophic characteristics. A cyanobacteria is photosynthetic, commonly called blue-green algae, and may produce toxins (Crayton, 1993). Bacteria are most commonly associated in the general

Microscopic  organisms  known  as  cyanobacteria are  interesting  for  the  following  reasons: [SELECT  ALL  THAT  APPLY] Select  one  or  more: A.  Oxygen  produced  by  their  photosynthesis is  thought  to  be  responsible  for  the  "great oxygenation  event"  about  2.3  billion  years ago.   B.  The  methane  they  produce  is  a greenhouse  gas  that  could  have  helped warm  the  early  Earth,  helping  to  resolve  the Early-­faint-­Sun  paradox. C.  The  chloroplasts  that  carry  out photosynthesis  in  green  plants  are evolutionary  descendents  of  early cyanobacteria.   D.  They  are  known  to  be  the  earliest  forms of  life  on  Earth.

The CO2 production was measured with a CO2 meter (+/- 1ppm), in order to determine the rate of anaerobic cell respiration in yeast.

The genus Halobacterium ("salt" or "ocean bacterium") consists of several species of the Archaea with an aerobic metabolism which requires an environment with a high concentration of salt; many of their proteins will not function in low-salt environments. They grow on amino acids in their aerobic conditions. Their cell walls are also quite different from those of bacteria, as ordinary lipoprotein membranes fail in high salt concentrations. In shape, they may be either rods or cocci, and in color, either red or purple. They reproduce using binary fission (by constriction), and are motile. Halobacterium grows best in a 42 °C environment. The genome of an unspecified Halobacterium species, sequenced by Shiladitya DasSarma, comprises 2,571,010

As we all know, efforts to reverse declination of worldwide fish stocks resulting from over fishing has led to an exploitation of the world’s fisheries. Nearly a third of the marine fish stocks has been overfished thereby influencing the destruction of ocean ecosystems. Secondary to over fishing is climate change. Increasing global temperatures coupled with increasing levels of carbon dioxide (CO2) is changing the marine landscape as we know it. Severe changes in ocean pH, temperature and salinity may in effect significantly reduce or eliminate populations of oxygen producing phytoplanktons. These single cell organisms produce more than 70 percent of oxygen as a byproduct of photosynthesis. Ensuring the long-term sustainability of our ocean

Over time, a cavity in the leaf developed that houses and protects the bacteria in a space without oxygen. The anabaena is then able to help the plant with nitrogen fixation. This cavity in the leaf also allows for cyanobacteria to be passed down through reproduction. (2)

Cyanobacteria, microscopic prokaryotic bacteria, are known for their green colour, their ability to convert sunlight into energy, with O2 as a
