Introduction Aim: To compare the effectiveness of compost and earthworms on the germination and yield of a spinach crop. Motivation: Fertilisers are mixture of chemicals that add nutrients to the soil to establish better yielding crops (Berger, 2013). Though these products have proved to provide many beneficial aspects to the agricultural sector, they have many negative environmental consequences. Fertilisers contain many substances, including mostly potassium, phosphorus, sulphur, calcium, magnesium and nitrogen. These substances, when they accumulate in the soil, can have harmful side effects on the environment and subsequently on the productivity of crops (Vimpany and Lines-Kelly, 2004).
2) Will the diploid cells as well as polyploidy cells denature at a rapid pace? 3) Will the type of soil affect the results? 4) Will changing the position of the plants in the sunlight alter the results? 5) Would the plants grow better in a small or larger container? 6) Which type of polyploidy plants will work best with this type of investigation?
In other words, at primary stages, most hydroperoxides were transformed into secondary oxidation products which is different from Teets and Were research (Teets and Were 2008) where there was an increase in the POV levels during the first 2-3 days of experiment. These outcomes indicate that performing a successful study about the peroxide value requires at least two tests in the first four days. There is no evidence as to the effect of lactoperoxidase enzyme on the production of hydroperoxides, nor was there any significant difference between lactoperoxidase coating samples and control A fillets on days 0, 4, 8 and 16. As seen in Fig. 1, the pH of A-L 6 sample is near the neutral point on day 12 as opposed to other days.
Blood agar is a type of growth medium (trypticase soya agar enriched with 5% Sheep blood) that encourages the growth of bacteria, such as streptococci, that otherwise wouldn’t grow well at all on other types of media. Blood agar has two major uses: To grow streptococci and to determine the type of hemolysis, if any. It can be used to distinguish between groups of organisms or species; it is therefore a differential medium. It is important to examine the area around an isolated colony for each
None of the populations showed statistical difference from the Wright equation calculated values, which was expected for the dark treatments but not for the light populations. These inconsistencies between predictions and results may be due to selective disadvantage against the white allele under light conditions and the effect of population size not being as strong originally hypothesized. The unexpected results may also be due to the high
In the research conducted by Cox et al., (2012), there were limitations in their sample. Their sample size was too small which makes it difficult to generalize the data and a claim a specific relationship. Further research should incorporate a larger sample size to be considered representative of people to whom results will be generalized and also to ensure a representative distribution of the population. Ineffective screening for comorbid disorders was another limitation in Cox et al., (2012) research. During the recruitment process, participants were only screened for MDD but not for any other comorbid disorders, which makes
Business Technology Early College High School Fertilizer Lab Experiment AP Living Environment Mr. Acquaotta/Mr. Lee Purpose The purpose that this lab was conducted was because we wanted to see if seeds germinated faster if fertilizer was applied. Introduction Fertilizer we use it when we garden, we see companies promote it in various ways, but have you ever wondered if it made a difference in growth of plants? Does it really make flowers bloom more rapidly or vegetables grow larger and more productive? The answers to these questions are all within the realm of science because they are testable by controlled experiments, observations and data gathering.
Thus, the amount of P liberated by them is generally not sufficient for a substantial increase of in in situ plant growth. Therefore, inoculation of plant by desire microorganism at adequate amount than the normal found in soil is necessary to take advantage of the property of phosphate solubilization for plant growth and yield enhancement (Rodrigues H and Fraga R, 1999). OBJECTIVES In the context of above observations, the present investigation was carried out with the following objectives: 1.1. Objectives of the Study • To isolate the phosphate-solubilize bacteria from rhizosphere of maize plants, • To detect the phosphate-solubilizing ability, • To characterize the microorganisms at the phenotypic and genotypic level, • To study the diversity of phosphate solubilizing bacteria, • To examine the production of organic acids, • In addition, this study was to examine the effect of phosphate-solubilizing bacteria as inoculants on plant growth and yield and may be used as biofertilizer. • We also hypothesize that the combined effect of microbial strain can also give better result as compared to the single
The question of interest is the following: what is the effect of nitrogen solution on duckweed growth? We want to know whether nitrogen will increase or decrease duckweed growth. In past experiments of the effects of nitrogen on plants, nitrogen was found to decrease plant growth when there was a deficit amount of nitrogen. An experiment was set up where plants were given 0%, 20% , and 100% nitrogen concentrations and were left for 58 days (Zhaoa, Reddya, Gopal, Reddyb, “Nitrogen deficiency effects on plant growth, leaf photosynthesis, and hyperspectral reflectance properties of sorghum”). They found, as a result, that the higher the nitrogen concentration the more growth in the plant sorghum.
Not only that, but only about 25 new medicines are released each year, which is absolutely nothing compared to the amount of medicines they test and the amount of animals they test upon, and that creates a pointless waste of innocent lives. Animal testing is wrong and should
Bean Beetle Methods draft Writeup Would different beans, other then mug bean make the bean beetles produce less offspring. In this group project we conducted a hypothesis that argues, If using different beans for reproduction other then the mug bean, then they will produce less offspring. the dependent vearable is number of offspring and the independent veraible is the different type of beans. when conducting this experiements we used method of division, replication, and messureing. In this experiment, we devided each of the different beans.
The purpose of this lab was to measure the amount of CO2 gas given off by germinated peas under certain conditions of light. We conjectured that the more amount of light the peas are exposed to, the higher the respiration rate they will have. Our data supported this because it showed that the germinated peas that were exposed to light 24 hours before the experiment had a steeper slope (as seen in table 1), therefore having a greater respiration rate. The peas that were not exposed to any light 24 hours before the experiment had a reduced rate because of its lack of exposure to light. Both pea’s respiration rates showed that the more light the peas were exposed to, the greater respiration rate they would have (Figure 1).
