The affinity of hemoglobin for oxygen is <u>increased</u> as the partial pressure of oxygen is raised.
Hemoglobin is the most vital constituent of red blood cells.
It is a kind of protein found in red blood cells that transfers oxygen to all parts of your body.
Hemoglobin is made up of proteins called 'heme' to which oxygen molecules become attached and travel throughout the body.
The blood carrying oxygen is called oxygenated blood and when it reaches the lungs, oxygen molecules detach and brings carbon dioxide along to remove it from the body through respiration.

Answer:
0.9904 m/s
Explanation:
To solve this problem we need to use the conservation of momentum:
m1v1 + m2v2 = m1'v1' + m2'v2'
Using this equation, we have:
m_bullet*v_bullet = m_bullet_after*v_bullet_after + m_block*v_block
0.00425 * 375 = 0.00425 * 114 + 1.12 * v_block
1.12 * v_block = 1.5938 - 0.4845
1.12 * v_block = 1.1093
v_block = 1.1093 / 1.12
v_block = 0.9904 m/s
Scientific Method: Because, they use their method which the scientific one to solve investigations.
<span>Even in space, there is still presence of gravity. The
cause of weightlessness is not how far above the earth the space shuttle is but
rather how fast it is travelling. The shuttle is in free fall causing
weightlessness, but it is travelling fast enough to miss the earth as it falls.
Similarly, the airplane could also provide weightlessness if it went free fall
as well. However, that ends as the plane hits the ground. </span>
