Answer:
I think you should be creative about this.
Explanation:
Maybe you can get a big piece of paper then get another one and draw people dancing, then cut them out, draw them, then stick them on the other paper. Next, all you have to do is draw the back round. That is what I would do. If I am wrong or this is not really your thing, then ask your parents for help, or your teacher.
The correct answer is: Changes in policy and representation in Congress. Hope this helps.
Answer:
This influx of economic migrants has exacerbated ethnic tensions within Russia. Because regional governments cannot pay their energy bills, clashes over energy has caused even more tension.
Explanation: Economic collapse has produced social dislocation and extreme poverty. Widespread corruption and the entrenchment of aging leaders and their families have eroded support for central governments and constrained the development of a new generation of leaders.
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 the, Kinetic Molecular theory, temperature is directly proportional to average Kinetic energy of gas particle
Explanation:
At the level of molecule kinetic energy model helps to understand the gaseous physical properties. The kinetic energy model is based on several concepts.
In the constant random motion gases are made of molecules or atoms.
The particles of gases are are constantly colliding with each other.
The particles of gas are small and the complete volume taken by gaseous molecules are negligible in comparison to complete volume of container.
Between the gas particle their is no repulsion or attraction.
Gas particles average kinetic energy is proportional to the fixed temperature of the gas, and all gas at the equivalent temperature have the equivalent average kinetic energy.
