Spherocytosis is a human blood disorder associated with a defective cytoskeletal protein in the red blood cells (rbcs). what do
Alex17521 [72]
In spherocytosis, there is a defect in the membrane proteins of the red blood cells, specifically ankyrin and spectrin. These membrane proteins contribute to the biconcave shape of red blood cells therefore the loss of these proteins will lead the red blood cells to lose its biconcave shape--leading to abnormally shaped red blood cells (spheres) hence the name. This can lead to premature destruction of red blood cells and jaundice due to hyperbilirubinemia. Spherocytes do not hold oxygen and carbon dioxide well as spherocytes have a decreased surface area.

vladimir1956 [14]

Answer;

Atomic number Tc = 43 , which is equivalent to the number of protons in nucleus.

Number neutrons = mass number - number of protons = 99 - 43 = 56 neutrons .

Number of electrons = number of protons - charge = 43 - (+7) = 36 electrons

Explanation;

-Atomic number is the number of proton in the nucleus of an atom of a given element. Mass number is the total number of protons and neutrons in the nucleus of an atom. A neutral atom has equal number of protons and neutrons.

-Isotopes are atoms of the same element with the same atomic number but different mass number.
