Answer 1

Hint: Anionic detergent is defined as a detergent in which the lipophilic part of molecules is an anion. For example: - soaps etc.
Antibiotics are a group of medicines that are used to treat infections caused by germs (bacteria and certain bacteria).

Complete step by step answer:
a)Anionic detergent is defined as a detergent in which the lipophilic part of a molecule is an anion and are the sodium salts of long chain sulfonated alcohol or hydrocarbon.
For example: - Soaps, synthetic long chain sulphate and sulfonate (sodium n-dodecyl benzene sulfonate and sodium lauryl sulphate).
b) Chemical has special importance in various fields of daily life as - in food, soaps and detergent. Chemical substances which are added to the food material to prevent their spoilage and retain nutritive value for a long time are called food preservatives. Chemical are used in food material for several other reasons like:
It is used in food for preservation.
To enhance the appeal of food.
To increase the nutritive quality of food.
c) Broad spectrum antibiotics act against the multiple stains and forms of different bacteria which share common structures and metabolic functions which can be attacked and affected to kill them.
Narrow spectrum antibiotics are more specific in their course and can act against only certain bacteria as a more targeted approach. It is used for the specific infection when the causative organism is known and not kills as many of normal microorganisms in the body.

Note:
Antibiotics are used to treat or prevent some types of bacterial infection. They are not effective against viral infection, such as the common cold, whooping cough or flu. Antibiotics should only be prescribed to treat health problems.
