(2a) Dentition pertains to the development of teeth and their arrangement in the mouth. … The dentition of animals with two successions of teeth (deciduous, permanent) is referred to as diphyodont, while the dentition of animals with only one set of teeth throughout life is monophyodont.

(2b) A tooth consists of enamel, dentin, cementum and pulp tissue. The portion of a tooth exposed to the oral cavity is known as the dental crown, and the portion below the dental crown is known as the tooth root. The dental pulp cavity exists in the center of the tooth, through which the dental pulp, called the nerve, runs. In order to receive an impact on the tooth and to absorb and alleviate the force on the jaw, the surface of the tooth root area (cementum) and the alveolar bone are connected by a fibrous tissue called the periodontal ligament. The tooth is supported by the tissue consisting of the alveolar bone, gums and the periodontal ligament.

(i) Enamel: The hardest bodily tissue covering the surface of the dental crown. It is as hard as crystal (7 on the Mohs scale of mineral hardness). (ii) Dentin: The tissue that forms the tooth from the dental crown to the tooth root, situated inside the enamel and cementum. It is softer than the enamel. A small tube filled with tissue fluid, called the dentinal tubule, runs inside the dentin. (iii) Cementum: The tissue covering the surface of the tooth root. It connects the alveolar bone with the tooth by the periodontal ligament. Its hardness is similar to bone. (iv) Dental pulp: The tissue is called the nerve. Blood vessels and the lymph vessels, as well as nerve fibers, are located in the dental pulp, supplying nutrients to the dentin.

(2c) (i) cellulose (ii) Starch (iii) Sugar

If you’re not interested in reading other essential information on this page, then click this link to quickly navigate to the WAEC Biology Past question papers section you want to visit.

Brief Information About The WASSCE

The West African Senior School Certificate Examination (WASSCE) is a standardised test taken in West Africa, mostly by students who wish to proceed to the higher institution. It is administered by the West African Examination Council (WAEC).

It is only offered to candidates living in Anglophone West African countries namely: Ghana, Gambia, Nigeria, Liberia and Sierra Leone and is written 3 times a year ( January/ February, May/June and Nov/Dec).

The WASSCE tests candidates according to the topics on the  WAEC syllabus .

The contents in each WASSCE Biology question paper (for a specific year) is usually similar from one country to another. Questions on the WASSCE Biology theory section may be specified to be answered by candidates from a particular country and this happens mostly in the theory section.

A WASSCE question paper on a particular subject may be entirely cancelled and changed in a region when the West African Examination Council (WAEC) heading that region suspects a leakage of examination papers before the start of the exam.

Benefits Of Regular WAEC Biology Past Questions Practise

Speed: Regular practise of WASSCE Biology past questions can go a long way in increasing your speed on the WAEC Biology exam day. It’s no secret that questions on the WASSCE for each subject are usually similar to questions in previous years since they’re from the same WAEC syllabus . WAEC also sometimes repeats questions  word-for-word.

Exposure: Regular practice exposes you to your weaknesses and gives you a chance to better yourself before the exam.

Decreases chances of anxiety: Regular and efficient practice improves your confidence before the exam.

These and many more are some beautiful benefits of practising WASSCE Biology past questions.

So it’s important you make it a habit to practise with WASSCE past question papers. There’s no doubt that this would help you achieve the grades you desire on the WASSCE on the long run.

Don’t just focus only on the WAEC past questions we provide on this page. We also have other WASSCE related resources that will be of great help to you.

Below this section are the Biology WASSCE past questions we have for now. Use them in accordance to the rules stated on this page and our Terms of Service.

WAEC Biology Past Question

Here is collection of Biology past examination questions to assist you with your studies for the West African Senior School Certificate Examination (WASSCE) for both School and GCE candidates.

If you are in your last stage of Secondary School Education (May/June) or not in the School system (GCE), the importance of using old exam papers in preparing for your West African Senior School Certificate Examination (WASSCE), cannot be over emphasised. By using past exam papers as part of your preparation, you can find out what you already know. By the same token you also find out what you do not know well enough or don’t know at all.

See: WAEC Timetable for May/June Candidates and WAEC Timetable for GCE Candidates .

What is more, the WAEC past questions for Biology can also be used as an organisational tool to manage your time better, as you can plan according to each section of the paper.

As a matter of fact, revision is more better than memorising facts and going over notes. You can practise for your Biology WAEC Exam by answering real questions from past papers. This will give you a better chance of passing.

General WAEC Biology Expos 2020

  • When you notice that your time is far spent and you are about to submit while you still have so many Difficult Questions to attempt, then you may have to stop cracking your brain and use our prediction method as explained above. BUT,
  • Don’t ever leave any Answers space blank. Don’t fail to answer any questions. Just choose an option if you don’t know the correct answers. That is better than leaving a question blank.
  • Ask your neighbor for an answer if possible.
  • Read and Understand what each Question is asking for before making an attempt of giving an answer.
  • Evaluate each answer option: After you might have finished reading and understanding a question, make an attempt of identifying the right type of answer that will answer the question even before looking at the options.
  • Eliminate each clearly wrong Answers. If you’re asked Questions like “what gender Is your father”? You don’t need an Oracle to tell you that the correct option will be “male”.
  • If every other option here fails, then guess like a magician. You may guess and get it correct.
