According to Table one, the leaf length, the leaf number, and the weight were higher than no nitrogen and high nitrogen. The height of the low nitrogen was a bit smaller than the high nitrogen, but the conclusion can still be made that the low nitrogen is used in order to grow the best Helianthus annuus plants. This is so because these plants need the macronutrient, nitrogen, in order for it to grow properly but it does not require a lot of the macronutrient. A lack of the macronutrient would make the plant grow slowly. This was the case with no nitrogen.
The PH of the soil: Soil PH is simply a measure of how acid or alkaline the soil is on a scale of 1-14 , and soil acidity or alkalinity (soil pH) is important because it influences how easily plants can take up nutrients from the soil; thus indicating the health of the soil. from 6.0 to 7.5. Below pH 6.0, some nutrients, such as nitrogen, phosphorus, and potassium, are less available. When pH exceeds 7.5, iron, manganese, and phosphorus are less available. Macro-organisms found in the soil: If a lot of worms or other organisms are found in the soil, it will indicate that the soil is most probably healthy enough for the access of people as it is not to acidic or alkaline to contain life because Earthworms need moisture and nutrients.
Martian soil actually contains the right nutrients for crops to grow, but the amount of nutrients in the soil varies. For the potatoes to grow, Mark Watney must use soil with a large percentage of nutrients, so he had to be lucky to stay in an area with lots of nutrients in the soil. Besides this, the Martian soil contains a lot of metal. The effects of this on human health are not known, so there is a possibility that this is toxic. Dave Lavery, Program Executive for Solar System Exploration at NASA headquarters, said: “In terms of basic mineral content and chemical content, yes it would be possible to grow plants in Martian soil.
There are many different substances available or added to the soil that can assist in plant growth. The main elements needed for plant growth are Carbon, Hydrogen, and Oxygen which the plant gets from the air and water. There are other macronutrients which include Nitrogen, Phosphorus, and Potassium which the plant either gets from decaying organic material or fertilizer.There are other minor nutrients a plant needs for growth such as Sulfur Calcium, Magnesium, Copper, and Iron. These elements are found naturally occurring or are added to fertilizer. People throughout history have used fertilizer to improve plant growth beginning with Native Americans who added a dead fish to plants coming to today where we use either chemical or organic fertilizers.
The reflux process lasted an hour after which the generated mixture was separated by a separatory funnel. The sulfuric acid functioned as the acid catalyst and worked to protonate the carbonyl carbon of the benzoic acid compound leading to a more reactive nucleophile. Protonation of the carbonyl carbon allows for the generation of a tetrahedral intermediate structure composed of both the benzoic acid and the methanol. The removal of water from the tetrahedral intermediate leads to tautomerized structure that becomes methyl benzoate when a loss of hydrogen is registered in the tautomerized oxygen.After the hour of refluxing was done, the resultant mixture was separated into an organic layer and an aqueous layer by means of a separatory funnel. The separation process was aided by a diethyl ether solvent the usage of which saw the aqueous layer to be the bottom layer of the refluxed
The nucleophilic attack pushes the carbonyl electrons onto the carbonyl oxygen, which forms a short-lived intermediate. The third step is where the oxyanion electrons reform the bond with the aromatic amino acid. Then the bond between the carboxyl-terminus of the amino acid and the n-terminus of the residue is cleaved and its electrons are used to take out the hydrogen of the nitrogen on the Histidine 57. The c-terminal side of the polypeptide is free to dissociate form the active site. Step four is basically just where water can now enter and bind to the active site through hydrogen bonding, which is between the hydrogen atoms of water and the Histidine-57 nitrogen.
There chemical formation is C6,H12,O6 and due to their bond angles between the carbons, tend to form a pentose of hexoses, stable ring structure. Each carbon atom is then numbered 1-6 and depending on the orientation of the OH group in carbon 1 will decipher weather the monosaccharide is either an a or b
Autotrophs make food for their own use but they make enough to support other lives as well. Photosynthesis gives the most energy for life on earth. A small group of
With the many advantages and disadvantages, which is better; GMO or Organic Food? Genetically modified organisms as we know it today is considered to have only negatives, but GMOs actually contain many positives. Such properties with crops like the conservervation of land and water resources are all possible because of genetic modifications. Crops today can be engineered to produce higher harvests from the same croplands. In some cases, the crop can double its production when the transition from traditional crops to GMO crops is completed by local farmers.
Effect of different physical conditions on nitrogen fixing bacteria from rhizosphere Hypothesis: Rhizospheric Nitrogen fixing bacteria show optimal growth at PH: 6-7, Temperature: 30 °C and Salinity level: 0.005 – 0.010M NaCl INTRODUCTION: There is a huge bacterial diversity in rhizospheric soil. Gram-negative, non-sporulating baccilli which respond to root exudates are predominant in the rhizosphere (Pseudomonas, Agrobacterium). While Gram-positive bacilli, Cocci and aerobic spore forming bacteria like Bacillus and Clostridium are rare in the rhizosphere. The most common genera of bacteria are Pseudomonas, Arthrobacterm Mycobacterium, Flavobacter, Cellulomonas, Agrobacterium, Alcaligenes, Azotobacter,
