Paramecium

Cells are very important because they are assumed to be the basics of life. There are two types of cells that exist: Prokaryotes and Eukaryotes. The interesting thing is that, even though the prokaryotes seem to be very different from the eukaryotes. For example, humans look very different from the bacteria, but they still do share some characteristics. No matter at which cell you are looking at: bacteria’s`, plants`, animals`, protists`, etc., they all will be bounded by a plasma membrane…

Ancient Greek debated whether living organisms were composed of endlessly divisible fluid or indivisible subunits. However, this debate was settled and closed with the invention of the microscope which is the required material to understand and observe cells. Let us begin with the ABC’s of the Cell Theory which splits into 3 major parts: All living beings are made up of cells Cells are the basic unit of structure in all organisms All cells come from preexisting cells. To have a deeper…

• Bacteria, are single-cell microorganism with no nucleus that had a sphere, rod, and spiral shape and branching threads. Ranges in diameter between (0.5- 1) µm and in length between (2-4) µm however, they are either a parasite or live independently they are found in all living things and in all environments. Some bacteria in drinking water can cause disease such as salmonella, total coliform (including fecal coliform and E.coli), Shigella, Legionella, and Campylobacter and “their presence…

unicellular or multicellular. (2) The cell is the basic unit of life. (3) Cells form from preexisting cells. (They are not derived from spontaneous generation.) These principles can be proven by multiple existing organisms in our world, such as Paramecium, a unicellular organism which still completes all the function of a living organism. It nutrition is based on smaller organisms and taking them in through endocytosis, a process in which a cell allows molecules/organism inside of it’s outer…

The second section of this paper discusses teaching strategies that use students’ first language, Spanish, to scaffold learning of the second language, English. It also discusses certain areas of the English language where teachers can support Latino students, such as phonology, phonics, vocabulary, sentence structure and writing. Spanish-speaking students enter the classroom with pre-existing knowledge of Spanish, or “linguistic capital” which improves their ability to master a second language…

Application of Biofloc technology in aquaculture systems; a viewpoint Anjali P. Thilakan1*,Manju Lekshmi. N2.,Sreekanth.G.B2, N. P. Singh2 1Central Institute of Fisheries Education, Andheri (W), Mumbai 2ICAR Central Coastal Agricultural Research Institute, Ela, Old Goa . Abstract Bioflocs are aggregates (flocs) of algae, bacteria, proto¬zoans, and other kinds of particulate organic matter such as feces and uneaten feed and it normally contains 35-40% of protein. Biofloc technology ensures…

As a rule, the gill area is greater in fast-moving crabs (Portunids) than in sluggish bottom dwellers; decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water…
