Which stable element is used to determine the age of volcanic rock? argon O carbon-14 O O potassium carbon-12 Which stable eleme

Verdich [7]

Answer:

Argon

Explanation:

Argon is actually used to determine the age. It's called potassium-argon dating b/c when volcano erupts the rocks in it contain potassium. The potassium slowly decays and produces argon. Scientists measure how much argon is in a given volcanic rock and do math backwards to figure out how many potassium atoms were needed to produce the given amount of argon. We already know the rate at which potassium decays so then they put two and two together to find the age.

Here's a link with some cool info on it:

<h2>Importance of Archaea And Bacteria </h2>

Explanation:

Microscopic organisms contain peptidoglycan in the cell divider.
Archaea do not.Explain the explanation that the <em>two kinds, microbes and archaea</em>, have a similar essential structures, yet worked from various synthetic parts.
The archaea and two microbes have cell films and the two of them contain a hydrophobic bit.
The two microorganisms and archaea have a cell divider that ensures them. it is made out of peptidoglycan, though on account of archaea.
The two microscopic organisms and archaea have diverse Ribosomal RNAs (rRNA).
Archea have three RNA polymerases like eukaryotes, yet microorganisms have just one. Archaea have cell dividers that need peptidoglycan and have films that encase lipids with hydrocarbons as opposed to unsaturated fats.
The two microscopic organisms and archaea have diverse Ribosomal RNAs (rRNA).
