In the atmosphere we see significant thermal disturbances that change density of gases and add water vapor, a low density gas. Gases tend to redistribute because of their varying densities. so we will not find deep layers of one gas above deep layers of another gas. We do have Brownian movement that cause accumulation, but the nature of a gas overrules any tendency to completely stratify based on density.
Answer:
(18+ Adulthood)
Explanation:
They might be in a relationship since they are both male and female and the fact they share private thoughts and disclose personal information. Also the fact that they are being intimate sums it all up.
We can actually deduce here that with the current neuroimaging techniques, all the following things can be measured non-invasively except: Neuronal firing rates.
<h3>What is neuroimaging techniques?</h3>
Neuroimaging or brain scanning technique is actually known as the use of various techniques to produce the image of the structure, function of the brain. It can be done directly or indirectly.
This neuroimaging makes it possible for neuroscientists to see the inside of the brain.
The options that complete the question are:
1.oxygen content.
2. blood flow.
3. neuronal firing rates.
4. physical structures.
Thus, neuronal firing rates is the correct answer.
