Answer: <span>95 to 133 bpm</span>
The equation for maximum heart rate would be:
max HR= 220- age
max HR= 220-30= 190
The equation to find the target for heart beat in medium intensity exercise would be:
target HR= max HR * 50-70%= 190 * 50-70%= <span>95 to 133 bpm</span>
Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the
H+ concentration in acidity/basicity. The more H
+ ions found in solution, the more acidic the substance is as acids donate H
+ ions.
You can calculate the concentration of H
+ from the pH and the equation
p
H =
−
log
[
H

arrange again
[

] = 10

So for a pH of 8, we get [
H
+
] =
10
^−
8
For a pH of 5, we get [
H

]
=
10^

= 1000
The correct answer is D: the adrenal glands. More specifically, the adrenal medulla<span> produces </span>catecholamines<span>, in particular especially </span>norepinephrine<span> and </span>epinephrine. Estrogen<span>, </span>testosterone<span>, </span>cortisol<span>, </span>dopamine<span> and </span>serotonin also play a role in the response.
No... I am pretty sure that is unlikely... you might on it, or you might just poop it out, but that about it.. XD
