Water ecology‚ which studies on the interaction between of biotic and abiotic factors to the growth of organism in water‚ is too important in order to keep the ecosystem balance. In our study‚ we focused on how the fertilize (nitro‚ phosphorus) effects on the populations of water organisms. Euglena is the mixotrophic which could synthesis energy from photosynthesis‚ but also could consume the food to make energy (Robert.et al‚ 2012). From the trophic characteristic of Euglena

benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction‚ in which the nitro group replaces a proton of the aromatic ring. Following recrystallization‚ melting point and infrared were used to identify and characterize the product of the reaction. Purpose: The purpose of this experiment is to synthesize methyl nitrobenzoate

and is manufactured in huge quantities. The starting material for the commercial manufacture of paracetamol is phenol‚ which is nitrated to give a mixture of the ortho and para-nitrotoluene. The o-isomer is removed by steam distillation‚ and the p-nitro group reduced to a p-amino group. This is then acetylated to give paracetamol. Method * Place 2g of the 4-aminophenol into a 50cm3 conical flask‚ add 15cm3 of water and stir the suspension vigorously (magnetic stirrer) for a few minutes.

Conservation of Energy In explaining the laws of conservation of energy‚ energy cannot be destroyed or made. Although‚ energy can be transformed or transferred from one form to another‚ for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned‚ and then used as thermal energy for heat‚ next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy‚ gravitational energy‚ electromagnetic

We then left the bowling alley and he continued to aggravate me as he went no more than fifteen miles per hour. Once we were passing the Moose Lodge in Nitro I had a plan in my head that I would take the back-roads in a stunt to beat him out. We were getting closer to the split right past the seven-eleven and I darted down the back-road. While driving down 2nd avenue I passed a car. I continued down the

Vegetative reproduction (vegetative propagation‚ vegetative multiplication‚ vegetative cloning) is a form of asexual reproduction in plants. It is a process by which new individuals arise without production of seeds or spores. It can occur naturally or be induced by horticulturists. Although most plants normally reproduce sexually‚ many have the ability for vegetative propagation‚ or can be vegetatively propagated if small pieces are subjected to chemical (hormonal) treatments. This is because meristematic
