Answer:
17,190 years
Explanation:
Each isotope has a characteristic half-life, which is the time required for half of that isotope to decay. After one half-life has elapsed, 50% of the isotope has decayed and 50% remains. After two half-lives, 75% has decayed and 25% remains. After three half-lives, 87.5% has decayed and 12.5% remains. For carbon-14, which has a half-life of 5,730 years, three half-lives corresponds to 17,190 years.
I think one of the statement here is erroneously written since A and B is the same statement. It should be that one choice is that "<span>Saltwater freezes at a lower temperature" and this is the correct answer. Saltwater experiences a freezing point depression due to the salt in the solution.</span>
The correct option is LOESS.
Loess refers to a compacted yellowish deposit of wind blown sediments which is usually found extensively in the mid latitudes. Loess is formed by the accumulation of dust that had been blown by the wind. Scientists believed that about 10% of the earth's land area is covered by loess.<span />

<h2>i HOPE IT'S HELP </h2>
You put this in the wrong category, but I will still help...
Number 1: 20 centimeters( just look at the graph)
Number 2: I am guessing 40 centimeters. I think you are calculating how long it took your bug to reach point B...
Hope this Helped!
