Academic Questions in Basic Science

The ultimate source of energy is _____.

  1. plants
  2. sun
  3. food
  4. water
  5. air
  6. earth

ANSWER is sun

Without the sun, there will be no life on earth. Even plants require the sun to manufacture their food. The mode of nutrition through which organisms manufacture their own food is termed autotrophic nutrition. Please read on autotrophic nutrition here.

Note: Every other form of energy directly or indirectly comes from the sun.

The speed of wind is measured with a wind vane.


ANSWER is false

The speed of wind is measured with an anemometer  while the direction of wind is measured with a wind vane

Meaning of Man's Uniqueness:

The uniqueness of man can be defined as that which makes man distinct from every other animal and living organism. Humans are higher animals when compared to other animals. They belong to the order primates and thus share the following characteristics:

  • They have their eyes in front on their head (stereoscopic vision)

  • They have a flexible shoulder joint

  • They have opposable thumbs and toes

  • They can stand erect 

  • They have bigger brains


The possession of a highly developed brain is the major attribute of man's uniqueness. This has enable man to reason, solve problems and advance in technology. Below are the effects of man's developed brain.

  1. Ability to advance language communication and speech

  2. Ability to know what's right and wrong

  3. Ability to create advanced technology like phones and automobiles.

  4. Ability to think and remember

  5. Ability to manipulate things with their fingers and toes


The Brain

The brain is one part of the central nervous system (the other part been the spinal cord). It is located in a part of the skull called the cranium. Human brains are highly folded and is generally divided into three regions:

  • Forebrain: It is the largest part of the brain and is composed of two halves of cerebral hemispheres. The cerebrum is responsible for the initiation and coordination of voluntary activity in the body.

  • Midbrain: It connects the fore brain to the hind brain. It serves important functions in movements of the eye, and in auditory and visual processing. It is also called mesencephalon

  • Hindbrain: It's composed of 2 lobes of cerebellum and the medulla oblongata. The medulla oblongata controls involuntary activities like breathing and swallowing while the cerebellum is responsible for voluntary movements.


Note: Intelligence may be defined as general cognitive problem-solving skills. It changes over time with age and can be inherited.

An intelligence quotient (IQ) is a score derived from a set of standardized tests developed to measure a person's cognitive abilities in relation to their age group. 

IQ may also be defined as the ratio of mental age (MA) to chronological age (CA) multiplied by 100

IQ = MA x 100 ÷ CA

MA = Mental age

CA = Chronological age

IQ above 100 = Brilliance

IQ that equals 100 = Average

IQ below 100 = Below Average

Amazing facts in Basic Science


All fruits have seeds. There is nothing like a naturally occurring seedless fruit. Even banana, coconut and pineapple have all got seeds.

Weight can be defined as the force of gravity acting on an object. If you traveled to space, you would be weightless because there isn't any force of gravity acting there. We all have weight on earth becasue the force of gravity acts here. Weight is measured in Newton

Massis the amount or quantity of matter/material contained in a body, For instance, everything you are composed of, both from within and outside will make up your mass. Mass is constant throughout the universe. You will have the same mass on earth and moon. Mass is measured in gram or kilogram. Mass is quite different from weight.

Matter is anything that has mass and occupy space. Matter can exist in four states namely:

  • Solid
  • Liquid
  • Gas
  • Plasma
