The <u>brachial artery</u> is located in each upper limb, therefore it supplies the upper limb and the lower limb's main arterial vessel is called the <u>femoral artery</u>.
<h3>What is brachial artery?</h3>
It is the main blood vessel that is responsible for transporting oxygenated blood to supplies the upper limb from where the arm begins until it divides into two branches (radial and ulnar), and culminates in the hand and fingers.
<h3>What is femoral artery?</h3>
The femoral artery is located in each lower limb, specifically in the anterior and internal part of the thigh, to later become the popliteal and tibial arteries, it transports the blood with oxygen that comes from the left ventricle.
Therefore, we can conclude that the femoral artery is a pathway that belongs to the vascular system, which supplies the lower limb's, and the brachial artery is a prominent blood vessel that is responsible for irrigating the tissues located in the upper limb.

The answer is B., Natural Selection.
Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.
So, the only answer left is natural selection, and it makes sense too!
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.

If there are respiring organisms within that sample of air, the partial pressure of oxygen decreases because the organisms utilize it for respiration activities.
