By using the genes from two bacteria producing organisms such as Alcaligenes Eutrophus, they could insert them into cress plants with the aim of these plants producing the PHB. This process worked and the plants and some of their offspring produced around 14% of the dry weight as PHB. Although this is not as high yielding as when it is produced in the petri dishes, it is a much more economically viable method of production and hence would give a much more substantial impact to society. Chemically PHB is from a group of biopolymers known as the polyhyroxyalkanoates. Figure 1 below shows other examples of biopolymers in
No details of how the oxides of nitrogen are formed are required, other than the fact that they are formed at high temperatures. Solid particles may contain soot (carbon) and unburnt fuels. b) The combustion of hydrocarbon fuels releases energy. During combustion the carbon and hydrogen in the fuels are oxidised. 18 GCSE Chemistry for teaching from September 2011 onwards (version 1.0) Additional
1916) This information uncovered new perspectives on hemp and helped me realize and become in favor of the industrial uses of hemp for our world and soil that we live on and use daily’s health, and I hope it does the same for you. This leads me to my next main point. The Hemp seed can be made into oil for cars, and for many other things including food. Hemp oil also burns cleaner then oil keeping our planet cleaner. The most amazing thing about hemp is it can even be made into unimaginable
At this time, there are still a lot of things unknown about GMOs and how it affects humans and the environment and going organic is the best option right now. Genetically modifying our food does have its advantages. The human population relies on food. If there is less food, the population declines, if there is more food, the population grows. This has happened throughout history.
If it does not melt, increase the time in the flame. If the solid melts under this increased heating, record it as medium melting. In the event the solid does not melt, record it as high melting. 3. Solubility- First, the solubility test was carried out in distilled water.

This type uses fermentation to produce useful products to humans by fermenting microorganisms such as: bacteria and yeast. In this world there are five important types of fermentation; microbial cells, microbial enzymes, microbial metabolites, recombinant products, and biotransformation. In industrial fermentation there are many important factors to consider so that the bacteria could ferment. Growth media is one of the main factors we need to consider in this process. Growth media refers to any liquid or gel that will support any microorganisms or cells to grow.
This may appear to be a very simple process; however, conditions have to be right for it to happen and for the bacteria to be viable. Under the right conditions they can divide and multiply rapidly. The term used for this process is binary fission. Bacteria exist everywhere, including inside and on our bodies. Most
We all boil water to make tea or dinner. This experiment will help us decide which water boils faster. First we will collect hot tap water, cold tap water and get sealed bottled water from the grocery store. Next we will measure equal amount of water. Boil hot tap
