conditions needed for the growth of micro-organismsWeegy:
Growth Requirements/conditions for Microorganisms are chemical and physical requirements. Chemical requirements. [ In order to grow successfully, microorganisms must have a supply of water as well as numerous other substances including mineral elements, growth factors, and gas, such as oxygen. Virtually all chemical substances in microorganisms contain carbon in some form, whether they be proteins, fats, carbohydrates, or lipids. Perhaps 50 percent of a bacterium's dry weight is carbon. Carbon can be obtained from organic materials in the environment, or it may be derived from carbon dioxide. Both chemoautotrophic and photoautotrophic microorganisms obtain their energy and produce their nutrients from simple inorganic compounds such as carbon dioxide. Chemoautotrophs do so through chemical reactions, while photoautotrophs use photosynthesis.Physical requirements. Certain physical conditions affect the type and amount of microbial growth. For example, enzyme activity depends on the temperature of the environment, and microorganisms are classified in three groups according to their temperature preferences: psychrophilic organisms (psychrophiles) prefer cold temperatures of about 0?C to 20?C; mesophilic organisms (mesophiles) prefer temperatures at 20?C to 40?C; thermophilic organisms (thermophiles) prefer temperatures higher than 40?C (Figure 1 ). A minimum and a maximum growth temperature range exist for each species. The temperature at which best growth occurs is the optimum growth temperature. www.cliffsnotes.com/study_guide/Growth-Requirements-for-Microorganisms.topicArticleId-8524,articleId-8423.html

explain the ways an infective agent might enter the bodyWeegy:
They can enter the body in various ways. Mouth, nose, skin, ear, eyes, etc. Any entry way for bacteria is an entry way for disease- causing agents. [ Hand contact with someone who has those agents can cause one to
Once contact occurs, disease-causing agents, such as viruses and bacteria, may enter a person through breaks in the skin, or they may be inhaled or swallowed. Others may enter the body through the moist linings of the eyes, ears, nose, mouth, or other body openings. source: WikiAnswers ] Auto answered|Score .9118|sharpies|Points 7288|User:
common sources of infectionWeegy:
Hand washing is a simple habit, something most people do without thinking. Yet hand washing, when done properly, is one of the best ways to avoid getting sick. [ This simple habit requires only soap and warm water or an alcohol-based hand sanitizer — a cleanser that doesn't require water.
Proper hand washing with soap and water
Follow these instructions for washing with soap and water:
Wet your hands with warm, running water and apply liquid soap or use clean bar soap. Lather well.
Rub your hands vigorously together for at least 15 to 20 seconds.
Scrub all surfaces, including the backs of your hands, wrists, between your fingers and under your fingernails.
Dry your hands with a clean or disposable towel.
Use a towel to turn off the faucet.
Proper use of an alcohol-based hand sanitizer
Alcohol-based hand sanitizers — which don't require water — are an excellent alternative to hand washing, particularly when soap and water aren't available. They're actually more effective than soap and water in killing bacteria and viruses that cause disease. Commercially prepared hand sanitizers contain ingredients that help prevent skin dryness. Using these products can result in less skin dryness and irritation than hand washing.
Not all hand sanitizers are created equal, though. Some "waterless" hand sanitizers don't contain alcohol. Use only the alcohol-based products. The CDC recommends choosing products that contain at least 60 percent alcohol.
To use an alcohol-based hand sanitizer:
Apply about 1/2 teaspoon of the product to the palm of your hand.
Rub your hands together, covering all surfaces of your hands, until they're dry.
If your hands are visibly dirty, however, wash with soap and water, if available, rather than a sanitizer.
Preventing the spread of communicable diseases means blocking transmission, or "blocking the chain of infection." This can be done by removing one or more of the conditions that are necessary for a disease to spread. ] Auto answered|Score 1
