  • Eutrophication Lab Report

    to all lakes over time as the weathering of rocks and soils from the surrounding area that leads to an accumulation of nutrients in the water. It can also be caused by run-offs of fertilisers. Three of the key components of modern fertilisers are nitrogen, phosphorous and potassium. After a rainy season these nutrients that were not absorbed, run off into waterways such as dams, lakes, rivers, streams, ponds and even sometimes swimming pools. The fertiliser triggers the growth of plants that are…

  • Carbon Dioxide In Recirculating Aquaculture Systems

    The removal of carbon dioxide in Recirculating Aquaculture Systems (RAS) has been an important topic of research due to the increasing amount of recirculating aquaculture systems being employed in the aquaculture industry. Carbon dioxide, as well as ammonia, are excreted by the fish and can be present in high quantities. Elevated levels of CO2 accumulation within the recirculating water could have toxic effects on fish. The maximum level of CO2 and ammonia that can be present in the tanks…

  • Azolla Case Study

    tropical regions. 2. What is unique about this fern? Why is it called ‘Azolla Superorganism’? This fern is unique because it is a little fern and has massive potential, and its called superorganism because it is symbiotic that captures all the nitrogen fertilizer it needs to grow from the air around it. In Asia, they grow it along with…

  • Analysis Of Apricot

    Raw material: Two sweet varieties of Apricot (Prunus Armeniaca L.) namely Marghulam and Halman fully ripened fruits were collected from Gilgit Baltistan region in Northern Areas of Pakistan. Apricots were sun dried under open condition (26-34+4 C, RH 41-52%) for 16-19 days. The sun dried Apricots were packed in polyethylene bags containing 01Kg of dried fruit. Further The dried samples obtained were ground to a fine powder and stored at 5°C in air-tight containers prior to further analysis.…

  • Fertilizers As Water Pollutants Summary

    Her work supported by both first-hand and second-hand research. In her analysis, she describes the natural nitrogen and ammonium levels in soil, followed by an explanation on how synthetic fertilizers negatively manipulate these levels. She details how this manipulation negatively impacts the microbial ecosystems within soil, which continues to have harmful effects…

  • Redox Homeostasis Research Paper

    Anthony Alvarado Bio 1A Chronic oxidative stress via hydroxyl radical and imbalanced redox homeostasis Redox hemostasis has been shown to be an important factor in the overall aging and neurodegeneration processes in mammalian models; such as, Alzheimer’s and Parkinson’s. As a result, redox homeostasis has been a key point of interest in current research. Redox homeostasis is the balance between electrophiles and nucleophiles in a system, more importantly in a biological system. These…

  • Pollinators And Flower Relationships

    Pollinators, flowers, and their relationship play an essential role in ecosystems. Pollinators are responsible for facilitating fertilization in flowering plants, which provides seed production in fruits and vegetables. Pollination is important in agricultural communities with the fertilization of crops. It is estimated that pollinators contribute to the global economy by adding 217 billion dollars from pollinating a vast array of crops (Gallai et al., 2009). The pollinator-flower relationship…

  • Determining Soil Nutrient Levels

    detected, the most common reason for undertaking soil analysis is to detect the levels of essential nutrients (Guo, 2009). The commonly analysed nutrients in most samples submitted to the laboratory include macronutrients like potassium, phosphorus, and nitrogen as well as their pH levels. McGrath and Skotnikov (1996) pointed out that knowledge about soil nutrient levels, in addition to relative comprehension…

  • Why Is Ammonia Important

    Why is ammonia important? The primary use of ammonia (NH3) is to provide nitrogen atoms for plants so they are able to make amino acids, proteins, and other biologically important molecules. In order to provide the vast amount of food demanded by a growing industrialised population, more efficient agricultural techniques and larger scale farms must be employed. There exists some naturally occurring nitrogen fixing bacteria that are able to convert atmospheric N2 into the more useful form of NH3…

  • Lemna Case Study

    Lemna is a free- floating aquatic plant from the duckweed family, that consists of small, individual thalli (Tkalec et.al, 2001). Lemna are small, fast growing plants and they develop dense mats on ponds, especially when enough light and nutrients are available (Gérard et.al, 2014). Salt is the most toxic substance, as it causes an inhibition of plant growth and a decrease in nutrient uptake (Chang et.al, 2012). Salt stress induces the production of abscisic acid (ABA), a plant stress hormone,…
