They have well-developed and symmetrical gills over which drawn water flows. The flow of water carries the waste and reproductive products. Movement: Although abalones occur in the same place, they may use their muscular foot with its suction power to move, cling and stay tight with the substrate surfaces. Feeding habits: In nature, abalone eats marine algae with a particular preference to large brown algae such as giant kelp and other kelp species. While juvenile abalone grazes for algae, diatoms and bacterial films, adults rely on drift algae, and if food becomes scares, they move after their food.
Marine organisms are animals, plants, and other living things that live in the ocean. A Marine biologist is a scientist who studies marine organisms and studies the bodies, behavior, and the history of marine organisms. They also study how marine organisms interact with each other and their environment. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its surrounding environment. To start off, a Marine biologist might study coral, crabs, fish, microscopic marine organisms, sea stars, seaweed, squid, or whales.
GC can be used for the direct separation and analysis of gaseous samples, liquid solutions, and volatile solids. If the sample to be analyzed is non-volatile, the techniques of derivatization or pyrolysis GC can be utilized. Gas chromatography (GC) has been an indispensable analytical technique in the application of fatty acid determinations in oilseed plant breeding, biosynthesis, and human metabolism. As well as the characterization of complex mixtures of geometric isomers when combined with other chromatographic separations and spectroscopic identification. Plant cultivators utilize GC as a more accurate and fast method to evaluate the differences and inheritance of fatty acids in oilseed crops such as rapeseed.
Increasing the amount of nutrients, rise alga and the number of microorganisms; up in water body. More aquatic plants growing need more oxygen and it will continue until oxygen depletion or phosphorus limitation. If oxygen finishes the whole system convert to non-oxygen based system. Discoloration, odor, and fish kill follow by oxygen depletion. In fact alga sinks to the bottom of pond after they die.
However, it cannot be used for reliable identification of specific substances. The mass spectroscopy instrument provides specific results but produces uncertain qualitative results. When an analyst uses the gas chromatography instrument to separate compounds before analysis with a mass spectroscopy instrument, a complementary relationship exists. The technician has access to both the retention times and mass spectral data. Many scientists consider GC/MS analysis as a tool for conclusive proof of identity.
Pond Ecosystem Investigation Lab report By: Harshal Buradkar 9 grade Introduction A pond ecosystem consists of abiotic: light intensity of the water, depth of the water, and biotic: fish, plants, bacteria, algae, insects and etc. It also contains water and plants which is the most important part of the pond. Ponds are mostly shallow with the depth of 12-15 feet in which the sun rays can touch the bottom of the pond so that plants can grow. My aim is to find out how the plant cover affect the biodiversity of animal life in the pond. Experimental question How does the plant cover affect the biodiversity of animal life in the pond?
unirradiated CMCS and irradiated CMCS were screened in vitro for their antibactericidal activity (against Gram positive bacteria S. aureus and Gram negative bacteria E. coli) and antifungal activity (against Aspergillas flavus and Candida albicans). In this method, a standard 5 mm diameter sterilized filter paper disc impregnated with samples (1 mg/ml of DMF) was placed on an agar plate seeded with the test organism. The agar plates were then incubated for 24 h at 37 °C for bacteria and 28 °C for fungi. After incubation, the interrupted growth zone (zone of inhibition) around the test material was measured (mm/mg) and used as quantitative indicator of antibacterial and antifungal effectiveness of CMCS. The values obtained were the average of 5 measurements on the same plate at different zones.
His research focuses on the Ecology and systematics of freshwater zooplankton and limnology, including studies on invasive copepods, long-term limnological research, palaeolimnology, freshwater biodiversity and aquaculture impacts. Freshwater ecosystems are a subset of Earth's aquatic ecosystems. It is a unique and important component of global biodiversity, playing a fundamental role in support of the environment, society and the economy. Ecosystems like wetlands, rivers, aquifers, and lakes are indispensable for life on our planet and are vital for directly ensuring a range of benefits and services such as drinking water, water for food and energy, habitats for aquatic life forms, and natural solutions for water purification and climate resilience, among many others. Freshwater ecosystems comprise of 0.8% of the earth’s surface but contain 6% of all known species.
