During exhalation, your respiratory muscles contract to push air out of your lungs.
Your respiratory muscles contract each time you exhale.
When you exhale, the primary muscle responsible for this action is the diaphragm, which contracts and moves upwards, reducing the volume of the lungs and forcing air out. Additionally, the intercostal muscles, located between the ribs, also contract and help in the process of exhalation.
In summary, your respiratory muscles contract during exhalation to push air out of your lungs.

b. examples are mountains, lakes, or oceans
c. over time, the isolated population can become very different from the original population
d. all of the above
Answer:
d. all of the above
Explanation:
Geographic means anything to do with the terrain or land. Isolation can happen for any amount of time, so you never know what the new population might be.
The reactant side of the given chemical equation C2H5OH + 3O2 → 2CO2 + 3H2O contains six hydrogen atoms.
The chemical equation in question is C2H5OH + 3O2 → 2CO2 + 3H2O. This refers to the reaction of ethanol (C2H5OH) with oxygen (O2), producing carbon dioxide (CO2) and water (H2O). From the chemical equation, the reactants side contains one ethanol molecule containing six hydrogen atoms. Hence, in terms of reactants, the number of hydrogen atoms involved in the equation is 6.

To count the rate of beating. For instance, if the heartbeat is 70 beats per minute and the stroke volume is 70 cm 3, the cardiac output is 70 70 cm 3 per minute, or 4900 cm 3 per minute.
The heart's left ventricle is the chamber that pumps blood to all the arteries. The left ventricle is the name for the lower left chamber of the heart. The heart's left ventricle serves as its primary pumping chamber. Left ventricular hypertrophy can cause stiffening of the thicker heart wall.
Because the pressure at which this chamber pumps blood is the same as that in all arteries, you can compute beating by measuring the pulse in the radial artery in your wrist. This artery is easier to discover beating because it is closer to the surface.
Therefore, to count the rate of the beating of the left ventricle, cover SV with your finger, and you are left with CO/HR.
