Below are Genetic causes of Sickle cell disease •MUTATION: sickle cell gene mutation probably arose spontaneously in different geographic areas, as suggested by restriction endonuclease analysis. These variants are known as Cameroon, Senegal, Benin Republic, Bantu and Saudi- Asian. Their clinical importance springs from the fact that some of them are associated with higher HBF level, e.g; Senegal and Saudi-Asian variants, and tend to have milder disease. •HETEROZYGOUS: in people heterozygous for Hgbs (carriers of sickling Haemoglobin), the polymerization problems are minor, be because the normal allele is able to produce over 50% of the haemoglobin. HOMOZYGOUS: in people homozygous for Hgbs, the presence of long chain polymers of Hbs distort the shape of the red blood cell from a smooth doughnut-like shape to ragged and full of spikes, making it fragile and susceptible to......continue >>> www.rowlandokonko.com/2016/02/Biology- Sickle-cell-anamia-genetics-diseases.html?m=0

Good day my awesome readers of Rowland Okonko's Education Arena. Today I will write on Colloids, Suspension, Solvents. COLLOIDS Colloid can be also refers as False solution or colloidal solution. In colloid the individual solute particles are larger than the particles of the true solution. True solution is when solute particles dissolve such that they are able to get in between the solvent particles, usually the resultant mixture in true solution is Homogeneous. Example is the aqueous solutions of sodium chloride. Colloid and true solution particles are not large enough to be seen by the naked eye. In a colloidal or false solution, the liquid solvent is more appropriately known as the Dispersion Medium and the solid solute particles constitute the Dispersed substance.....

Below are tips on How to Be a Gentleman. To be
a gentleman isn't easy at all.
•For that final bit of added flair, use a
pocket square to add a dash of colour.
•Always make sure you are as clean as you can
get! If you are on the run all day long, use a
deodorant that lasts more!
•Respect other people. When you don't like
someone or don't agree with them, say nothing
or just say ¿I hear what you say, but don't agree
with you!
•Always be punctual and try not to cancel your
appointments! Unless you have a good reason,
there is no excuse!
•Many stains can be..... Continue >>>www.rowlandokonko.com/2016/01/tips-on-how-to-be-gentleman.html?m=0

An acid is a substance which produces hydrogen ions (or protons) as the only positive. Ion when dissolved in water. There are two classes of acids • Organic Acids, Examples ÷ • Ethanoic acid (from vinegar) • Fatty acid (from fats and oil) • Citric acid(from lime and lemon) • Ascorbic acid (vitamin C)(from oranges) • Lactic acid (from milk) • Amino acids (From proteins). • Inorganic Acids, Examples ÷ Tetraoxosulphate (vi) acid ( H2SO4) • Trioxonitrate(v) acid ( HNO3) • Hydrochloric acid (HCl). Ionization is when an acid dissolve in water to produce hydrogen ions, as the only positive ions, together with the corresponding negative ions. Strong acids ionize completely in water to give. Hydrogen ions and anions. The concentration of hydrogen ions is very high in such acid solutions. Examples.

• The arrangement of their atoms or molecules in
crystal lattices when in the solid state. Below are

Welcome, today I shall write on respiration. Air
enters the body either through the mouth or the
nostrils (external openings leading to the nasal
cavity). The mouth and the naval cavity opens
into the pharynx. Pharynx is a short passageway,
which branches at the end in two directions. One
leads to the digestive tract, and the other to the
larrynx (voice box) and the lower air pathways.
Glottis is the entrance to the larynx. During
swallowing, a flap (epiglottis) covers the glottis to
prevent food and liquid from entering the air
pathways. When the glottis opens, air enters the
larynx. The larynx leads to the trachea (wind
pipe) which branches into two bronchi (singular:
bronchus), the air tubes that enter the lungs.
Each bronchus branches repeatedly within the
lungs to form smaller air tubes. All these air tubes
are kept open by incomplete rings of cartilage to
allow air flow. The smaller air tubes are called
bronchioles. Very fine branches of the

Today I shall write on Genes. Genes are discrete units of inheritance which determine hereditary characteristics. They are found on chromosomes in the nuclei of all cells. All the information for the inheritable characteristics of an individual are contained in these genes. When a cell divides, the genes duplicate themselves, so that each daughter cell has an identical set of genes as the ...More click >>>www.rowlandokonko.com/2016/01/gene-definition.html?m=0

Sickle-cell anaemia is usually a fatal disease
caused by the formation of abnormal
haemoglobin S instead of the normal
haemoglobin A. Haemoglobin is a protein, a
complex molecule made up of amino acids.
Both
haemoglobin A and S molecules are alike except
in one amino acid. This difference in structure is
due to a mutation in the gene for haemoglobin.
In
the mutated gene, one of the base codes on
the
DNA that should read as the amino acid,
glutamic
acid, has changed to read as another amino
acid,
valine, instead. As a result of this change in
structure, haemoglobin S is less soluble than
the
normal haemoglobin A. The haemoglobin S
molecules tend to clump causing the red blood
cells to become 'sickle-shaped'. This results in

Today I shall write on the care of our skin. The skin is in direct contact with our surroundings and gets dirty easily. We should therefore take proper care of the skin and keep it clean. A balance diet containing vitamins A and B2 (riboflavin), and regular exercise are especially important in maintaining a healthy and supple skin. We can maintain a healthy skin by taking sufficient vitamin A in our daily diet. In the tropics (like Nigeria) we sweat a a lot. Sweat and oily secretions from the skin make dirt and dust stick to the skin. The stale sweat gives off an unpleasant smell. Such a dirty skin becomes an ideal breeding ground for micro-organisms and.....continue here >>> www.rowlandokonko.com/2016/01/care-of-skin.html?m=0
