Protozoa is a unicellular organism, which is made
up of Eucaryotic cells in which the cell structure
is complex with a well-defined nucleus. Protozoa
belongs to the kingdom Protista. Protozoa are
animal like Protista because they feed on ready-
made food and have no cellulose cell walls.
Amoeba and Paramecium are examples of
Protozoa. Below are some protozoa diseases of
human beings÷ TRYPANOSOMA GAMBIENSE÷

Bacteria is a procaryotic cells that belongs to the
kingdom Monera,bacteria is a simple living
organism that is enclosed with rigid cell walls.
Bacteria is a microscopic organism that can only
be seen through the high power of a light
microscope. They are found in air,soil,inside living
organisms and water. Bacteria can be motile or
non-motile some motile ones have whip-like
structures called Flagella which enable them to
move about in water. Below are some diseases of
human beings. SHIGELLA DYSENTERIAE÷ causes
Bacterial dysentery. Can be contracted by food

Today I shall list some diseases of human beings
that are virus. Virus as we all know is not
classified as living or non-living thing, because
when it is not on the host body it acts as a non-
living thing but once it enters the body of the
host, it start behaving as a living thing. Below are
some virus diseases of human being. VIRUS

Today I will write on, types of skeletons Found in animals. There are three types which are Hydrostatic skeleton, Exoskeleton and Endoskeleton Hydrostatic skeleton÷ earthworms are soft-bodied animals that uses fluid pressure to provide support. Tubular animals like earthworms have a muscular body wall. Fluid is secreted to fill the spaces in the body. The fluid presses against the muscular body wall, which causes the muscles to contract, exerting a force against the fluid. This.....

In our last post on materials found on the
skeleton we talked about Bone. Today I shall talk
on cartilage Cartilage÷ cartilage tissues are found
in the skeletons of complex vertebrates. It
consists of living cells called CHONDROBLASTS,
PROTEIN FIBRES and CARBOHYDRATE. Cartilage is
a very flexible and tough tissue with a great
tensile strength. Cartilage also acts as a shock
absorber by cushioning the effect of bones
moving against bones when we move. It forms
the entire skeletal system of sharks and rays.
Types of cartilage in mammals÷ there are three
types such are Hyaline cartilage, Fibro-cartilage
and elastic cartilage The Hyaline cartilage make
up the rings which support the trachea and
bronchi and keep them open. It also supports the
protruding part.... More click here >>> www.rowlandokonko.com/2016/01/materials-found-in-skeleton-continuation.html?m=0

As we all know that Cell is the functioning unit of life, cells are made of seven types of substances such as Water, Nucleic Acids,Minerals,Vitamins,Proteins,Fat and Oil and Carbohydrate. The properties and functions of a multicellular organism are the sum total of the properties and functions of its constituents cells. Cells are essential for the growth and reproduction of Plants and Animals. Cells contain protoplasm and cell membrane, that means the nutrients they need for their activities, growth and repoduction are similar. Cellular Respiration (catabolism) As we...

Silicon as we all know belong to group 4 and

In 1772 and 1774 oxygen was discovered by
Scheele and Priestley. Lavoisier was the one that
first described oxygen as the essential for the
combustion of substances. Oxygen means Acid-
producer Oxygen is the must abundant element
on earth. Free oxygen constitutes about 21% by
volume of atmospheric air and 33% by volume of
dissolved air. Combined oxygen make up about
50% by mass of the earth's crust Laboratory

The chloroplasts contain the green pigment
chlorophyll, which absorbs light energy from
sunlight. This energy is used for the splitting or
photolysis of water molecules to give hydrogen

All vertebrate classes exhibit reproductive
methods ranging from external fertilization/
internal fertilization, Oviparity / Viviparity /
Ovoviviparity During External Fertilization, the
female vertebrate lays eggs into the surround
water and the male ejects sperms over them.
When the eggs are fertilized by the sperms, the
sperms develop into young outside the mother's
body. The developing young ones feeds on
stored food in the eggs for fast development.
While in Internal Fertilization. Fertilization occurs
inside the body of the female. The male places
the sperms inside the body of the female
through the reproductive opening. The eggs
some things remains in the female's body. In
Oviparity, eggs are shed into the external
environment where the embryos complete....more click here. >>> www.rowlandokonko.com/2015/12/types-of-fertilization-in-vertebrate.html?m=0

.In our last lesson I talked about the first twenty
element and their symbol/nickname and atomic
number, today I shall discus About Hydrogen and
its property. Hydrogen was discovered by
Cavendish in 1766. Lavoiser named it hydrogen,
meaning water-former. Hydrogen is found free
only in very small amounts about 0.01% in the
atmosphere and in volcanic gases. Hydrogen can
be preparated in the laboratory by the following÷
when certain metals react with dilute mineral
acids, water or steam Hydrogen is liberated.
Hydrogen is also liberated when Tin,Zinc or
Aluminium reacts with hot concentrated

Topic : Benefit of Giving Thanks
Text : Deut. 28:47, 48 ; Psalms 103:1


The Bible also encourage us also to give thanks in everything. One of the things that brings provocation is failure to say thank you especially when you shouls say it. This season is a season of saying to God thank you for preserving our lives.

Thankful ness should occur because of the goodness of God, not because of perfect circumstances. In Psalms 100:4,5- Enter his... Continue here >>> www.rowlandokonko..nl/2015/12/spiritual-alert-today_12.html?m=0
