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:

MissTica

Answer:

It is likely that the genomic sequences that were used did not enable to properly observe the evolutionary relationships among the species analyzed

Explanation:

The homology level between the genomic sequences may be too low to separate species that are phylogenetically related. In these cases, it is necessary to make a genetic analysis of the sequences that are used before the phylogenetic analysis

With reference to the induced fit model, describe how the tertiary structure of a named enzyme facilitates its function as a bio
Olenka [21]

The induced-fit model includes the change in the conformational site of the substrate and enzyme. It is done till the enzyme completely binds the substrate. This will then activates the enzyme to perform its work.

<h3>What is induced fit theory?</h3>

Induced fit theory or model suggest that the activation site of enzymes and the binding site of substrates undergo some conformational changes to fit into each other.

This binding results in activation of the enzyme and as the enzyme has a three-dimensional tertiary structure, this would help it to get fitted into the substrate.

Thus, with reference to the induced fit model tertiary structure of enzyme facilitates its function as a biological catalyst.
