Answer:
Explanation:The Biosphere-Atmosphere Interactions focuses on the sources and sinks of greenhouse gases (GHGs), air pollutants, particulate matter, water, and energy between the Earth's surface and the atmosphere.
The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
<u>Canadians</u>
- Sample size = 50
- Mean = 4.6
- Standard deviation = 2.9
<u>Americans</u>
- Sample size = 60
- Mean = 5.2
- Standard deviation = 1.3
The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:

The standard error of the Canadian sample is:

So, we have:

The standard error of the American sample is:

So, we have:

The standard error of the difference of sample means is then calculated as:

This gives


Take square roots

Hence, the standard error of the difference of sample means is 0.444

The answers are hyper cortisol response and higher levels of physical aggression.
<h3>What is hyper cortisol?</h3>
When the body is exposed to excessive quantities of the hormone cortisol for an extended period of time, hypercortisolism, also known as Cushing syndrome, develops.
Mike lives in the northern united states (in minnesota) and nick lives in the southern united states (louisiana). when they both feel insulted by the same individual, nick will be more likely to have a(n) hyper cortisol response and show higher levels of physical aggression.
Cortisol is a stress-inducing hormone, according to research on hormones in the human body. Now, it has been proved that when it is hot in the summer, the cortisol hormone circulates in the blood in a very significant amount. This can result in frustration as well as physical hostility.
Thus, the answers are hyper cortisol response and higher levels of physical aggression.
