Answer:
Before the end of the war allowed photographs of the camps, the evidence was anecdotal at best. There was hopes of people to bomb the camps but it would change nothing.
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.

When the supply of loanable funds shifts its position to the left, interest rates will rise because loanable funds will be more scarce.
Keeping demand constant, a shift to the left in the supply of loanable funds raises interest rates while decreasing the total quantity of loanable funds available.
The demand curve for loanable funds is sloping downward, indicating that when interest rates are low, borrowers will demand more funds for investment. The supply curve for loanable funds is upward sloping, indicating that lenders are willing to lend more funds to investors at higher interest rates.
Deficits reduce the supply of loanable funds; surpluses increase the supply of loanable funds; and surpluses shift the supply of loanable funds.

Answer:
1. Driving above the speed limit
2. Hit and run
Explanation:
John was speeding, he was moving above the speed limit, crossed the centerline and hit another car into the ditch.
A case can be filed against him for not obeying traffic laws.
The second case could be manslaughter (if the driver in the other car died) or at the very least he could be charged with careless driving, intent to harm or disregard for human life (by fleeing)
