Answer and explanation;

-Common-vehicle exposure is an outbreak occurs in the group of people who have eaten the food. single exposure is when food may be served only once, for example, at a catered luncheon.

-Properties of a single-exposure, common-vehicle food borne outbreak includes;

-Such outbreaks are explosive; there is a sudden and rapid increase in the number of cases of a disease in a population.

-The cases are limited to people who share the common exposure. This is self-evident, because in the first wave of cases we would not expect the disease to develop in people who were not exposed unless there were another source of the disease in the community.

-In a food-borne outbreak, cases rarely occur in persons who acquire the disease from a primary case. The reason for the relative rarity of such secondary cases in this type of outbreak is not well understood.

Explanation:

Any blow with mechanical damage, change in temperature or pressure, UV radiation, plutonium, strontium, X-rays, electricity, loud noises is considered physical noxa.

Examples of this can be: Physical hazards: noise, radiation (ultraviolet, x-rays), electricity, blows, breaks, burns, cuts.

Chemical noxa is toxic and poisons, mostly of exogenous origin, that enter the body accidentally.

Examples of this can be: Chemical noxes: insecticides, pesticides, poisons, toxic gases, co2, co.

Biological noxas are living beings or viruses recognized as pathogenic agents, since they cause diseases of varying symptoms, evolution and severity, but which are called infectious diseases.

Examples of this can be: bacteria, protozoa, fungi and non-cellular entities, such as viruses.

Psychosocial noxas are actions or lack of actions that can cause mental disorders and that can lead to physical problems. Its impact is often negative on general well-being, particularly for young people.

What is the function of monomers and polymers in protein

IRINA_888 [86]

Answer:

They are the monomers of the proteins.

Explanation:

When hundreds or thousands of amino acids join together, they create proteins, which are then used for many tasks in organisms, such as doing work in cells, help with DNA replication, etc. So, the monomer will be the amino acids, and the polymer will be the proteins themselves.
