Answer:

Wheel and axles

Explanation:

Clocks run on a complex system of gear trains. This provides the energy to turn the hands of the clock. A high-ratio gear train gears the weight drum way up so that you don't have to rewind the clock very often. This somehow disengages, slips or ratchets the gear train so the clock can be rewound and set.

What color is a carrot
Amanda [17]

Answer: Many people assume the original carrot colour is orange, when in fact all the different carrot colours available nowadays come from one common, colourless ancestor, the wild carrot (Daucus carota).

The taste difference between different colored carrots like orange, purple, red, white, and yellow isn't extreme. It isn't even as wide a range as different colored tomatoes. Yet there is some bit of a change to the flavor. It's often slight and it's subtle, mainly showing up when eating carrots raw. You can also understand the taste difference in different colored carrots by cooking them up or roasting them.
