What does a blue or pink color in thioglycollate mean?
A blue color in thioglycollate indicates the presence of oxygen in the growth medium, as oxygenated environments turn the indicator dye blue. In contrast, a pink color signifies that the medium is anaerobic, as the dye is reduced in the absence of oxygen, turning pink.
What flag is blue with an orange circle in the middle?

Why do flags wave in the wind?
Once there is any instability, a high pressure zone on one side of the flag moves the fabric, and the wind interacts with the fabric to translate the bumped out region in the downweb direction. Meanwhile the fabric interacts with the wind to increase the flow into the high pressure area and make the bumping out effect stronger. The displacement of the fabric travels toward the free end of the flag as a moving wave, and the free end flops back and forth, approximately following an arc around a point near the end of the flag. This travel in an arc creates a tension in the end of the flag (from the point of view of a coordinate system based on the flag, this would be centrifugal force). The coupling of wind energy into this traveling wave is what powers the fabric motion, much as it powers surf energy by coupling into ocean waves.
I'd consider this a problem from the field of mechanical engineering, more specifically an example of fluid-structure interaction (fsi). To model it effectively would require coupled models, one of them a computational fluid dynamics (CFD) model, and the other a mechanical model including the tension, mass, velocity, and possibly stiffness of the points in the flag. This is somewhat hard work.
Seems totally out of place in a chemistry exam, unless they want some sort of trick answer like solar energy driving the cycle of winds on Earth.
You dont. On a 220 circuit, the black is 110 hot, the red is 110 hot, the white is neutral, and the green is ground. You have to have 4 wires to get 220. If your appliance has only three wires, black, white, and green, it is not 220, but 110. You may have 220, with the white being the other hot. The only way to know is to trace the wire or check it with a meter. Either way, if you only have 3 wires there is no safe way to install a 4-prong outlet onto this wiring! Don't try it. Rerun the wire or call an electrician. Do it fight or don't do it at all, your negligence could kill someone. The person above is wrong. There are safe, and UL certified ways to do this assuming your heater is like most 220v appliances.
Many large appliances offer the capability to use either a 3-prong or 4-prong plug. In fact, most appliances nowadays don't even come with the cord, because they expect you to buy the one that matches your house wiring (be it 3 or 4 prong). Look near where the cord goes into your heater. Is there an access panel you can remove to see where the cord is wired into it ? Open that panel and look inside, you should see a block with 4 screws, three of which go to the three wires in the cord, the other will have a small metal strip connecting the middle screw to the 4th screw that has no wires screwed into it. At any hardware store, you can buy a new 4-prong cord for your appliance. They typically cost under (US)$20 . To install that cord onto your appliance, you simply unscrew each of the 4 screws in your heater, remove the metal strip between the middle and 4th screws, then install your new cord by connecting the center Neutral wire (typically white), the two 110v hot wires (typically red and black) on each side of the neutral, then the ground wire (typically green, or bare copper) to the 4th ground screw. Once you have your new cord installed, plug it in and enjoy your new heater ! Additional Info: That chord has improper coloring for 3-wire 220 hookup. White should always be ground. Technically, the copper doesn't care and a copper wire covered in white carries current as well as one in red. In your case green is ground and black and white should go to power. The bad part is that white is always assumed to be a safe (ground potential) wire for 110 circuits and should be red (or blue) for the other hot side of a 220 circuit.

The Pan-African flag, also referred to as the UNIA flag, Afro-American flag or Black Liberation Flag, is a tri-color flag consisting of three equal horizontal bands colored red, black and green. It was originally created as an official banner to represent an international community for all African people. Influenced by the members of the Universal Negro Improvement Association and African Communities League (UNIA). The organization formally adopted it in article 39 of the Declaration of Rights of the Negro Peoples of the World [1] on August 13, 1920, during its month-long convention held at Madison Square Garden in New York City, United States.[2][3]The flag can and has been used to represent African or African American unity or pride.

- black: black people whose existence as a nation, though not a nation-state, is affirmed by the existence of the flag; and
- green: the abundant natural wealth of Africa.
