Answer: 200 feet
Explanation: Making a U turn is making a turn of 180 degrees to an opposite direction.
their are rules in making a U turn while driving and they are:
1. Make sure there is no sign prohibiting you from making a u turn.
2. There must be a U turn only sign at the point.
3. There must be a 200 feet in each direction before the U turn is made.
4. Keep the vehicle on the right side of the lane in preparation to make the U turn.
Answer:
A common form of fossilization is permineralization. This occurs when the pores of plant materials, bones, and shells are impregnated by mineral matter from the ground, lakes, or oceans. ... Sometimes the mineral substance of the fossils will completely dissolve and other minerals replace them.
The first description of the DNA (deoxyribonucleic acid)chain was done by Watson and Crick in 1953, the nucleotides that constitute the DNA are four: cytosine (C), guanine (G), timine (T) and adenine (A). When doing a model is essential to remember that cytosine ONLY joins guanine and timine only link adenine, this is due to the size and chemical properties of each molecule. Later, another related and similar and molecule was discovered, the ribonucleic acid or RNA, which also is constructed by nucleotides.
In both cases, the nucleotides are compound of 3 main components: a nitrogen base, a pentose and a phosphate. When the molecule lacks the phosphate group, is called nucleoside. Depending on the chain ( DNA or RNA) the nitrogen base derives from purine (adenine and guanine) or pyrimidine (cytosine or timine) just in the RNA instead of timine is uracil (U)
The union is established between adjacent molecules through the phosphate, while among each other through the nitrogen base-remember C=G and T or U=A. The core of each molecule is the pentose. Therefore the best representation of the molecule is attached

I believe the answer is: Stop
The message 'stop !!' is usually used in a distressful situation where it is necessary to grab the attention of people near you.
For most people, it is easy to get the attention because our voice tend to rise in volume when we say 'stop'. For those who use hand signal, the sign must be really obvious and easy to understand by other people near them.
