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.
Helpful microorganisms. Here are some examples of useful microorganisms. When bread is made, a microorganisms called yeast is added to the dough to make the bread rise. Yoghurt is made by boiling milk and adding special bacteria to it.The bacteria turn the sugar in the milk into acid.The acid makes the milk go thick and stops any harmful bacteria growing.hen bread is made, a microorganisms called yeast is added to the dough to make the bread rise.
