Happiness could be anything. It could be the every day things you do that makes you grateful. It could be the fact the you have shelter over your head when you go home or the shoes you have on. Happiness is how you feel towards something and how it makes you feel.
They were equal as men in all aspects except occupation. Egyptian women often went about their business in the city including shopping for jewelry (a very popular activity for women from 3000 BC - Present Day lol) They basically didn't have to work (unless they were servants) and raised children. In return they were grateful to their husbands for providing money.
A standing ovation is <span>a period of prolonged applause during which those in the crowd or audience rise to their feet.
Please give me brainliest I only need one more</span>
I would say the following:
1) access to food and water. This means that they should be next to water sources (rivers) and fertile ground
2) construction material: wood and/or stones
I would say that a location on a trade route would also be beneficial (and rivers were trade routes: this explains why so many cities were on rivers!)
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.
