How can culture society and politics be likened to the parts of human body

sveticcg [70]

The correct answer to this open question is the following.

Culture, society, and politics can be likened to the parts of the human body in that they are closely related and are key components of the structure in a society. Culture, society, and politics play a key role in the development of societies, as the body systems are necessary for the human body to live in healthy conditions.

Culture, society, and politics are very particular for every country, the same way that every human body has specific characteristics that make it unique. When one of those aspects fails, society feels it and there are moments of chaos. The same way when somebody system fails, the whole body is affected.

A spoonful of dry baking powder is added to a glass of cold water and identical quantity is added to a glass of hot water which

Mashcka [7]

Answer:

Bubbles will form first in the hot water.*

A general rule in chemistry is that reactions proceed faster

at higher temperatures. Thus, the acid/base reaction which

produces the carbon dioxide bubbles you see, will happen

faster at a higher temperature.

*These results may depend upon the type of baking powder

you are using. There are actually three types: fast acting, slow

acting, and double-action. Fast acting works at room temperature,

as soon as the powder gets wet. Slow acting only works at oven

temperatures, and would probably not do much even in hot water.

And double-action works a little at both high and low temperatures.
