Answer: Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point. All known liquids, except helium, freeze when the temperature is low enough.
The answer is C buddy. Hope this helps :)
Answer: Plant trees or vegetation
Explanation: They help keep the soil in place.
Answer: The common ancestor of humans and chimpanzees had 24 pairs of chromosomes, and at some point in the human lineage, two chromosomes fused end to end, providing some selective advantage.
Explanation: Humans evolved in a different way due to external factors and at some point in the human lineage, two chromosomes blended giving humans a selective lead.
Answer:
The correct answer is -
- 5,730 Approximately
- carbon-12 isotopes
- carbon-14 decays at this steady rate
Explanation:
Half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years so the Carbon-14 has a half-life of 5,730 Approximately
.
As Carbon-14 unstable it is considered a radioactive isotope of carbon, carbon-14 will inevitably decay back to carbon-12 isotopes.
Radiocarbon dating is a method utilized by researchers to learn the ages of organic examples. It very well may be utilized on objects as old as around 62,000 years.
Radiocarbon decays gradually in a living being, and the amount lost is ceaselessly renewed as long as the living being takes in air or food. Since carbon-14 decays at this steady rate, an estimate of the date at which an organism died can be made by estimating the measure of its residual radiocarbon.
