<span>The anterior end of an earthworm contains an organ that detects smells. Evidence of this is the way the earthworms responded to the ammonia. The earthworms backed away from the ammonia when it was waved near their anterior end, but they did not respond at all when the ammonia was waved near their posterior end.</span>
<span>Suffocation is a most leading reason of death in grain storage
bins. Grain handling industry is a high hazard industry where workers can be
exposed to numerous serious and life threatening hazards. These hazards
include: fires and explosions from grain dust accumulation, suffocation from
engulfment and entrapment in grain bins, falls from heights and crushing
injuries and amputations from grain handling equipment. </span>
Multiply 5730 years by 2 since two half-lives have gone by for carbon.
<u>Explanation</u>:
The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years
The half-life of carbon-14 is 5730 years.
In this manner, after
1 half-life there is 50 % = 1/2 of the first amount left.
2 half-lives there is 25 % = 1/4 of the first amount left.
25% is two half-lives.
Every 50% of life requires 5730 years.
So two half-lives require 2 × 5730
