Answer:
Explanation:Following are the techniques or methods or approaches we can say that were used by the scientists to determine the geologic age:
1. Relative age dating
2. Absolute age dating.
3. Radiation measurement.
4. Stratigraphic superposition.
5. The fossil record.
The scientists used the method of relative dating to divide Earth's past in different chunks of time when alike organisms were on Earth. After that, to discover the actual number of years ago that events occurred, the scientists used the method of absolute dating.
So basically water is a polar molicule. So when it comes to the structure, water is able to form many hydrogen bonds and the way the atoms are able to bond together adds to the water's special properties.
It can be a heat insulator, which means it can trap heat in and reduce heat loss to keep us warm.
it can also protect organs, it can act as a shock absorber
None of the provided choices provide a completely correct answer. In fact, 75% of humidification takes place in the nose and mouth, with the rest taking place in the trachea. When you breath in, mucous
membranes inside the nose and mouth release
moisture to air. It is estimated that the average adult evaporates 200 to
300 ml of water per day during this process. The process is very efficient: while breathing in through
nose or mouth, the mucous membranes are cooled down. During breathing out, this cooling effect causes condensation of some of the moisture in the air coming from the
lungs, thereby moisturizing the mucous membranes
