What is the process of chemotaxis?
What is the process of chemotaxis?
Chemotaxis is a fundamental biological process in which a cell migrates following the direction of a spatial cue. The cells of higher organisms develop more sophisticated machineries to sense and process the information conveyed by the chemical gradient.
What is the meaning of chemostat?
A chemostat (from chemical environment is static) is a bioreactor to which fresh medium is continuously added, while culture liquid containing left over nutrients, metabolic end products and microorganisms are continuously removed at the same rate to keep the culture volume constant.
What is chemostat biotechnology?
A chemostat is defined as a steady-state bioprocess, where a microbial culture is continuously supplied with nutrients at a fixed rate and concomitantly harvested to keep the culture volume constant.
What is the purpose of chemotaxis?
Chemotaxis allows a bacterium to adjust its swimming behaviour so that it can sense and migrate toward increasing levels of an attractant chemical or away from a repellent one.
What is the introduction to the theory of plates?
Introduction to the Theory of Plates. Charles R. Steele and Chad D. Balch Division of Mechanics and Computation Department of Mecanical Engineering Stanford University. Stretching and Bending of Plates – Fundamentals. Introduction. A plate is a structural element which is thin and flat.
What is the chemiosmotic hypothesis?
In 1961, Mitchell proposed what would be called the chemiosmotic hypothesis. It is a theory which states that adenosine triphosphate, or ATP, synthesis in a respiring cell comes from the electromechanical gradient that is found across the inner membrane of mitochondria.
What is the theory of plate tectonics Quizlet?
The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
How did the Tharp Heezen map support the theory of plate tectonics?
The data and observations represented by the Tharp-Heezen map became crucial factors in the acceptance of the theories of plate tectonics and continental drift. The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle.
