Answer:
66986.51 g/mol
Explanation:
According to this question, Hemoglobin- an oxygen carrying compound in the blood, is found to contain 0.3335% iron (Fe) by mass.
* One molecule of hemoglobin contains four atoms of iron
If 1 atom of Fe = 55.85g/mol
Then 4 atoms = 4 × 55.85 = 223.4g/mol
So there are 223.4g/mol of Fe in one molecule of hemoglobin
If hemoglobin contains 0.3335% iron by mass, this mathematically means that:
223.4g/mol of Fe ÷ molar mass of hemoglobin = 0.3335%
That is;
223.4/M.M = 0.3335/100
Cross multiply
0.3335 M.M = 22340
M.M = 22340 ÷ 0.3335
M.M = 66986.51
Hence, the molar mass of hemoglobin is 66986.51g/mol.
I'd have said the lungs as it's responsible for gas/particle exchange
Answer:
The epididymis is the tube which moves the sperm from the testicles. Vas deferens. This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac. The vas deferens is between the epididymis and the urethra and connects these together.
Explanation:
Cohesive and adhesive properties of water are involved in essential biological properties such as nutrients intake.
<h3>What is the cohesive property of water?</h3>
This describes the tendency of water to create strong bonds between molecules.
<h3>What is the adhesive property of water?</h3>
This describes the tendency of water to create strong bonds with other molecules.
<h3>How are these properties related to life processes?</h3>
- Cohesion makes it possible for plants to move water from their roots to other parts of the plants.
- Cohesion causes it is easier to regulate the inner body temperature.
