Which property of argon makes it useful for potassium argon dating

Biology
2 answers:
Kruka [31]2 years ago

Potassium-Argon dating has the advantage that the argon is an inert gas that does not react chemically and would not be expected to be included in the solidification of a rock, so any found inside a rock is very likely the result of radioactive decay of potassium. Since the argon will escape if the rock is melted, the dates obtained are to the last molten time for the rock. Since potassium is a constituent of many common minerals and occurs with a tiny fraction of radioactive potassium-40, it finds wide application in the dating of mineral deposits. The feldspars are the most abundant minerals on the Earth, and potassium is a constituent of orthoclase, one common form of feldspar.

Answer: Inert substance

Explanation:

Potassium and argon makes it useful for potassium-argon dating, which is a method that is used to determine the time of origin of a rock.

This is done by measuring the ration of radioactive argon to ratio of radioactive potassium in the rock.

As argon is an inert element so it does not disappear from the rock and remains in it.

What are 2 suffixes that the scientific sugar names end with?
leonid [27]
The two suffixes that scientific sugar names end with would be -ose and -saccharide. Most often, when chemicals are sugars their names end in -ose, such as glucose and fructose. However, -saccharide is a Greek term which means sugar. Given that their scientific nomenclature are complex, monosaccharides and disaccharides often end in the suffix -ose.

Which one of the following best describes the functions of carbohydrates with living things?
kozerog [31]

It’s between b and d. I would go with b based on the information below.

The four primary functions of carbohydrates in the body are to provide energy, store energy, build macromolecules, and spare protein and fat for other uses. Simple carbohydrates are quick energy sources, but they do not usually supply any other nutrients or fiber. One of the most important functions of carbohydrates is to form a structure called the glycocalyx. This is a coat around the cell.

What Earth science concept explains the process of the cooling of magma into porous rock? Explain your answer. plz answer correc
Zolol [24]
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).
