But now the parallel force is the mass of the object * g * sin (theta), where g is the acceleration due to gravity (9.8 m/s^2) and theta is the angle of the inclined plane. For the perpendicular vector, the magnitude is the mass of the object * g * cos (theta). Let's give this a try.
Microorganisms in food production Nature uses microorganisms to carry out fermentation processes, and for thousands of years mankind has used yeasts, moulds and bacteria to make food products such as bread, beer, wine, vinegar, yoghurt and cheese, as well as fermented fish, meat and vegetables.
Microorganisms are used in brewing, baking and other food-making processes. The lactobacilli and yeasts in sourdough bread are especially useful. To make bread, one uses a small amount (20-25%) of starter dough which has the yeast culture, and mixes it with flour and water.owever, many eukaryotes are also microorganisms. Eukaryotes are characterised by the presence of organelles in the cells; these structures are absent in bacteria and archaea. The nucleus is an organelle which houses the DNA. A mitochondrion is vital in production and conversion of energy inside a cell.
