In the blood of an infant there are about `1.3 xx 10^(12)` red blood cells, which contain a total of 0.15gm of iron ions. On an average, how many iron ions are present, in each red blood cell of an infant? [Fe = 56]

Number of red blood cells present in 1 ml of blood

Mammal which contains nucleated red blood cell is:

Red blood cells contain (0.9% salt) which of the following solutions would be hypotonic to the blood?

The following simplified diagram refers to the outline plan of the circulation of blood in a mammal, Study the diagram and write the number and the name of the blood vessel in each case as mentioned under. Which vessel will contain the smallest number of red blood cells per unit volume of blood ?

Human blood contains three primary cell types: red blood cells (RBC), white blood cells (WBC), and platelets. In an adult male, a single microliter (1xx10^(-3) milliliters) of blood contains approximately 5.4 xx 10^(6)RBC, 7.5 xx10^(3) WBC, and 3.5xx10^(5) platelets on average. What percentage of an adult male's total blood cell count is compresed of red blood cells ?

Which of the following three statements is correct about RBC in mammals? I.Red blood cells circulating in the blood have nucleus. II. Red blood cells have similar function to white blood cells. III. Red blood cells are produced by the bone marrow.

The red colour of blood is due to a compound called "haemoglobin". It contains 0.335 % of iron. Four atoms of iron are present in one molecule of haemoglobin. What is its molecular weight? (At. mass : Fe 55.84)

If 10 centimeters of blood contains 1.2 grams of hemoglobin, how many grams of hemoglobin are contained in 35 cubic centimeters of same blood?

Iron (II) oxide has a cubic structure and each unit cell has a size of 5 Å . If density of this oxide is 4 g cm^(-3) , calculate the number of Fe^(2+) and O^(2-) ions present in each unit cell. (Atomic mass of Fe = 56, O = 16, N_(A) = 6.023 xx 10^(23) and 1 Å = 10^(-8) cm)
