Q2a
The solar system consists of a central star, the Sun, and all
of the smaller celestial bodies that
continuously travel around it. The smaller bodies include eight planets: Mercury,Venus, Earth, Mars, Jupiter, Saturn, Uranus,
and Neptune, which are themselves orbited by more than 140 moons.
2b
First off, we humans can only survive on earth
Most other planets also have volcanoes, mountains, and some are said to have had rivers
It is the only planet that can support life, the only one that has liquid water and the only planet that life can survive on.

(1) Departing boats gradually sink below the horizon, as do buildings on the shore from the viewpoint of the sailors.
Admittedly this only proves the earth is round right where you are--the frisbee hypothesis.
(2) "The sphericity of the earth is proved by the evidence of ... lunar eclipses,"
Aristotle says. "For whereas in the monthly phases of the moon the segments are of all sorts--
straight, gibbous [convex],
crescent--in eclipses the dividing line is always rounded.
Consequently, if the eclipse is due to the interposition of the earth, the rounded line results from its
spherical shape" Of course a frisbee, properly angled, would make a round shadow too. But if the Frisbee rotated while the eclipse was in progress, the
curvature of its shadow would change.
The earth's does not.
Q3

Q4a
A geographic information system ( GIS ) is a computer system designed to capture, store, manipulate, analyze, manage,
transform, and present all types of
geographical data .
4b
H a r d w a r e
Hardware is the computer on
which a GIS operates. Today,
GIS runs on a wide range of
hardware types, from
centralized computer servers
to desktop computers used in stand-alone or networked
configurations.
S o f t w a r e
GIS software provides the functions and tools needed to
store, analyze, and display geographic information.
D a t a
Maybe the most important element of a GIS is the data. Geographic data and
related tabular data can be collected in- house or bought from a commercial data
provider
M e t h o d s
A successful GIS operates according to a well-designed
plan and business rules, which are the models and operating practices unique to each organization.
4c
i Perform geographic queries
ii Improve organizational integration
iii GIS help in Making better decisions.
iv it also help in Making maps easly.

The father of two of the abducted girls in Chibok reveals about the last call he received from his daughter when the school was attacked by Boko Haram.
Correspondent of CNN, Isha Sesay, reveals that she had the most difficult conversation with a father that has two daughters kidnapped by Boko Haram, and 4 other women in his family were kidnapped by this radical Islamist organization.
In total his family misses 6 members that were kidnapped, they do not know where they are.
That father revealed about the disturbing phone call he got the night of the kidnap, when one of his daughters said that she believed there was something wrong and that school was under the attack of Boko Haram.
The father went from door to door to his neighbours asking whether they had any calls from their daughters and they said they heard the same. The whole neighbourhood was in panic.
One of the fathers in that area said he received a call from his daughter that said:
��Daddy, Boko Haram are here, they are taking us away they are loading us in a vehicles. Please tell mommy that she may not see me again. Please tell Mommy to pray for me.��
That father never heard from his daughter again

When Samuel was old, he made his sons Judges over Israel. The first-born was Joel and the second Abiah. They were Judges in Beersheba. But Samuel sons walked not in his ways. They turned aside after gains,took bribes and perverted Judgement. Due to this maladministration, all the elders of Israel went together to meet samuel in Ramala to complain.
The complaints centered on the perverted activities of his sons. The people then demanded for a king to judge them like other nations. The subject displeased Samuel when the people said, "give us a king to judge us". and Samuel cried to the Lord in prayer. The lord answered Samuel to listen to the voice of people in all that they say, for they have not rejected Samuel but rejected him, God,that he should reign over them.
(2b)

1 mole of B contaoins 6.00*10(^23) ions of OH(-)

WHY STUDENTS FAIL
Have you ever wondered how you failed your exams(waec/neco/nabteb)?
Do you think you got fake runz?
Answer;
(1) Most of the students dont have anything in their brain, all they know is facebook,2go. twitter, play games etc.
even if you pass your exam eventually, how do you tink you can cope in theuniversity or polytechnic
without knowing something.
(2) As a standard, astudent is expected to know 60-80% of the entire syllabus.
how many can you topics can you boast of
(3) Most students are not serious. imagine the following:
most student will just write it the way they see it
tabulate
X:1,2,3
Y:3,5,7
instead of interpreting it asother examples
tita-?
pie-?
sqr rut- ?
So how do you want to pass if you can interpret our symbols correctly.
(4)Bad center/ black listed center:
some of you dont make research on the center you are writing exams, you just register anywhere you and when you fail you want to push the blame on someone else. What you dont know is that some center result have been bad since 3years ago.
(5) Student caught in the exam hall:
Once a student is caugth cheating or involved in any malpractice, such a student sthould neverd expect his/her results.
(6) Cheap/fake runz
Alot of website are out there gving free or fake runz. imagine such a site not considering the results of students, compose fake answer or give the students fake runz. Most of the fault goes to students risking their own exams for cheap runz.
(7)Waiting to get free runz when we post it:
Normally, we do post answer late on the site for those that can pay for the runz,
obj posted 5mins to the end,
theory posted 20mins to the end.
Tell me how do you want to pass by waiting for free answers when those that paid for the runz has finished, you are just starting.
What you dont know is that nothing is free, even in freetown. Learn how to pay for what you need most. Be wise and try harder to pass

Minister of
Education write your
Address, Address of Adressie
then salute Dear sir here is the
body of the latter Firstly, rising
teacher's social status is a
more
convincing way than
increasing the salary. Because
nowadays the
teachers are not short of
salary, they are actually lacking of
the social values.
If people treats them not just
being teachers, moreover, as
honorable educators to
respect, that would have a better
effect than just
rising their incomes. If
people respect the teacher, that
means people
consider the education as a more
important business, which is
the teacher's
really demanded.
Therefore, increasing the
teacher's social
values,which is a satisfication
spiritually, would play a more
significant role than
just adding their salaries.
Furthermore, improving the
"hardware" of school is
another one of the
best ways to solve the problem.
Students do not
only acquire
knowledge from their teachers
and textbooks. They could learn
from
the curious things all the time so
that the hardware
is gradually play as
a key. "hardware" means the
equipment of school
such as Gym center,
swimming pool, Chemistry labs,
etc, which students could
acquire
education practically. I think
those are the high-
quality educations
because students actually
sdtruggle or fight for the
answers. According
to the labs or the swim practices,
students can truly learnt
from them.
For example, I used to feel hard
to remember all
sorts of the principles
of the chemical reactions,
indicating that they are
difficult to keep in
memory. However, after I did the
labs, the reactions were even
hard for
me to forget because I really saw
how the reactions
happened and truly
learnt from those labs. So with
the better hardware
in school, the higher
quality the education will be.
Therefore, I am firmly conviced
that there are
certainly several ways to
increase the education quality
more efficiently than
increase the
teacher's income, such as
increasing their social
attention or spending money on
the school equipments. your

What is wrong with Boko Haram and their sponsors: why are they making human life worthless?
As you read this, scores of students travelling to write JAMB exam in Borno State have been reportedly killed by the dreaded Boko Haram sect. They were among several persons that lost their lives in multiple attacks that were unleashed by the sect in four communities.
A senator from the area said:”What happened in Borno was beyond understanding. It is a must for me to speak since the people lives are involved and they are my people. All these are happening in my constituency and it will be wrong to keep quiet. I feel so much pained and would not have spoken but definitely my conscience will not let me do that.”
The Senator who is representing Borno Central in the Senate, Zannah Ahmed, on Friday accused the military of complicity in the latest attack where he said that 210 people were killed in attacks on four towns.
The towns included Dikwa, Kala Balge, Gambulga and Gwoza.
The senator claimed that the attackers were all dressed in military uniforms and spoke English language. This was a departure from the Hausa and Kanuri language spoken by the Boko Haram insurgents.
He even lamented that authorities of the military post in Gamboru, which purportedly received a distressed call from the people of Kala Balge avoided the town, claiming that it was not in its area of command.

SPECIMEN A: YOUNG MAIZE PLANT
SOIL REQUIREMENT: well drained loam and silt loam with fine tilth.
METHOD OF PROPAGATION: It is propagated by seed
planted manually, mechanically
VARIETIES/TYPES: dent,flint,sweet,flour,pop corn
CLIMATIC REQUIRMENT: (20degreec-30degreec)
RAINFALL OF 760mm- 1520mm per annum is used.
==============
SPECIMEN B:MALE FLOWERS OF MAIZE PLANT
It's also called:"TASSEL",is failrly compact and much branched. the main axis carries spikelets and these
consist of one SESSILE and PEDICEL.
each flower is composed of an oval,concave lemma enclosing a membranous palea with the three stamens and two lodicules. when the flower matures, the anthers are exposed. the anthers may be purple,pink or yellow.
===============
SPECIMEN C: FEMALE FLOWERS OF MAIZE PLANT
It's also known as the COB or EAR. Is has a modified lateral branch derived from an auxilliary bud of the main stem. the husk of the female inflorescence is formed from modified leaves and
this gives protection to the flowers and the developing seeds. the ovary is surmounted by a long style, the silk of which emerges from the top of
the husk. pollination is by means of wind and
gravity,the grains are more pointed at the end where it is attached to the cob. they are made up of
ovary, style and stigma.
