Answers:
The need for a variety of services
The disposable income of elderly population
Labor shortages
Explanation:
global aging refers to the change in economic, social, and political situation in a country after one generation grows older.
When people grow older, they will increase the need for healthcare services. The inability to produce as much output will resulted in lower disposable income for elderly population and labor shortages that make it harder for companies to fulfill the demand from the mark
1. Samples of a microbial colony obtained from the natural environment are not pure culture. They are mixed cultures because the environment consists of an array of microorganisms and not one specific organism. A sample obtained from the natural environment such as water or soil may contain several species of microbes that need to be further isolated to obtain a pure culture.
2. Isolation streak plate technique involves the dilution of the sample several folds and then streaking a small amount using a sterile inoculation loop on an agar plate in a zig-zag manner. This is done to obtain a pure culture of bacteria from a mixed population by separating the microprocessor. When the sample is diluted into a small concentration and is streaked onto agar placed, widely spaced, discrete colonies of bacteria can be observed. These isolated colonies can be further cultured to obtain pure cultures by picking and re-streaking them on fresh agar plates.
3. A microbial colony is considered a pure culture because it consists of single species. A single species of bacteria cluster and form an isolated colony on an agar plate which can be further plated on fresh medium.
3-1 - If your agar plate shows discrete uncluttered colonies then you have obtained an isolated colony. The following picture might help you to understand.
3-2. If you subculture isolated microbes into a sterile nutrient broth without any contamination, it will still be considered pure culture because it is single isolated species in a sterile aseptic environment of the nutrient broth.
3.3. A pure culture can become a mixed culture due to contamination. This could be caused by airborne bacteria if your conditions are not aseptic. Contamination is possible if the work area is not clean and sterile or if the glassware is not sterile. The contamination can transform your pure culture into a mixed culture and is hence problematic. So, it is very important to maintain a sterile and aseptic environment, glassware, and instruments.

According to Stephen Covey, when you use a win paradigm, parties in potential conflict work together to develop new solutions that make them all winners.
Explanation:
Paradigm is a philosophical model that contains set of concept and patterns, methodology etc. It has instinct of impress anyone's self confidence. When someone use win paradigm parties who are in conflict work they together develop new solutions that make them all winners.
That means it develops self esteem, confidence which lead them towards success. As paradigm contains models, self concept so anyone can put forward his views about certain thing. That's why Stephen Covey emphasized win paradigm.
