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:
stronger
Explanation:
A magnet can pull up a metal object because it is stronger than the gravitational force of the entire planet.
<h3>Answer</h3><h3>option B</h3><h3>38 N</h3><h3>Explanation</h3>
Given that,
mass of block A = 14kg
mass of block B = 12kg
angle alpha equals = 19°
<h3>Formula to find tension in the wire connecting blocks A and B</h3>
Tension in wire connecting weight of object A and B is due to weight of block B
= mgsin19
due to slope we will take horizontal components of weight, mg
= 12(9.81)sin(19)
= 38.3
Answer:
a) 4.98m/s²
b) 481.66N
Explanation:
a) Using the Newtons second law of motion
m is the mass of the object
g is the acceleration due to gravity
Fm is the moving force acting along the plane
Ff is the frictional force opposing the moving froce
a is the acceleration of the skier
Given
m = 60kg
g = 9.8m/s²
= 35°
Ff = 38.5N
Required
acceleration of the skier a
Substituting into the formula;
Hence the acceleration of the skier is 4.98m/s²
b) The normal force on the skier is expressed as;
N = Wcosθ
N = mgcosθ
N = 60(9.8)cos 35°
N = 588cos 35°
N = 481.66N
Hence the normal force on the skier is 481.66N
