Are Foods that allow microorganisms to grow are called parasites?
No. A parasite is an organism that lives at the expense to and causes harm to another organism. Foods that allow microorganisms to grow are media (singular medium).No. If the foods might allow pathogenic microorganisms to grow, they are called potentially hazardous.
How does sugar preserve food?
Sugar preserves food by lowering the water activity (aw). If the aw is 85 or less, spoilage and pathogenic microorganisms can't grow. Microorganisms all need proper food, water, temperature and acidity to grow and adding sugar to appropriate levels can prevent bacterial growth.
What is the stage in which microorganisms grow and reproduce?
The stage in which microorganisms grow and reproduce is called the log or exponential phase. During this stage, microorganisms rapidly multiply and increase in number.
Can microorganisms grow?
Yes, microorganisms can grow and multiply under favorable conditions such as temperature, pH, nutrients, and moisture. They reproduce by a variety of methods including binary fission, budding, and spore formation.
What does microorganisms that cause food to spoil need?
Food spoilage microorganisms all need these things, but the specifics may be different* Food * Water * Proper Temperature * pH * OxygenNot all spoilage organisms prefer the same conditions.Thermophiles like it hot. Psychrophiles like it cold. Most pathogens are Mesophiles - they like what we like.Yeasts and molds will grow under acid conditions.Clostridia will form toxins only under anaerobic conditions. Some bacteria can grow both with or without air.
What are the effects of micro-organisms on food?
Microorganisms help break down and decompose food. These microorganisms are what cause food to spoil and grow mold on it.
What illness food characteristics affects the ability of microorganisms to grow in food?
density
Food that allow microorganisms to grow are called parasites true or false?
True
What substance can microorganisms grow on?
Microorganisms will grow on almost anything organic. Microorganisms need 6 thing to live and reproduce. remember them with the acronym FATTOM Food, the right Acidity, Time, Temperature (40-135 degrees Fahrenheit), Oxygen, and Moisture

How do microorganisms on food grow and spread so quickly?
Because they try to get away from your mom Because they try to get away from your mom
Why can a dried food be keep longer?
Spoilage and pathogenic microorganisms need moisture to grow. When you remove the moisture to below the level that they need, the food will last longer.
What is the stage in which microorganisms grow and reproduce?
The stage in which microorganisms grow and reproduce is called the log or exponential phase. During this stage, microorganisms rapidly multiply and increase in number.
Can microorganisms grow?
Yes, microorganisms can grow and multiply under favorable conditions such as temperature, pH, nutrients, and moisture. They reproduce by a variety of methods including binary fission, budding, and spore formation.
What bactirea needs to grow?
What Microorganisms Need to Grow (FAT TOM): FOOD - Proteins and Carbohydrates ACIDITY: Pathogenic bacteria grow best in foods that are slightly acidic (pH of 4.6-7.5) TEMPERATURE: Pathogenic bacteria grow best between 41°F and 135°F (the danger zone). This is why leaving food at room temperature for several hours is very dangerous. Note: Foods left outside the danger zone doesn't necessary kill microorganisms, for example, refrigeration temperature doesn't necessary kill microorganisms but just slow their growth. TIME: When organisms are given favorable temperatures, proper nutrients and water they can double in population as quickly as every 20 minutes. If foods are left in the danger zone for 4 hours or more microorganisms can grow enough to make someone ill. OXYGEN: Some microorganisms need oxygen to grow and some can grow in the absence of oxygen. MOISTURE: Most microorganisms require water to grow therefore they grow well in moist food. Potentially hazardous foods grow best with a .85 or higher water activity level.
What Four factors which affect the growth of microorganisms?
Four factors which affect the growth of microorganisms are: temperature food source for microorganisms (ie. sugar, protein, fat) the amount of microorganisms introduced to the food source ph of the food source
