OBJECTIVES SOLUTIONS

• Most plants respond to stimulus slowly

. Growth in plants continues as long as the plant lives. In animals however, growth is limited. An animal grows for a while and then growth ceases. • Carbon (IV) oxide is not a raw material for respiration. Instead, it is a product of respiration.

2. C: • Waterleaf plant is Organism level • Kidney is Organ level • Spermatozoon is Cell level • Virus is at the borderline between living and non-living things

3. D: • X represents a dicotyledonous root while Y represents a monocotyiedonous root

NB The presence of root hairs is enough to inform us that the diagrams do not represent stems.

4. A: The part lebelled I’ is xylem. It is re- sponsible for the conduction of water and mineral salts.

5. A: I Xylem II pith III cortex

6. B: The organelles which are referred to as suicidal bags are the lysosomes. They earn this name due to the fact that they can destroy other cell components.

7. C: Plasmolysis is simply the loss of water from a cell when the cell is placed in a hypertonic solution. This loss of water causes shrinking.

8. A: Cambium contains meristematic cells. These cells are capable of active

9. D: Human has 4 caudal vertebrae, rabbit has 16 while rat has 27-30

10. B: The haemoglobin in erythrocytes transports oxygen to individual body cells for tissue respiration. Also, carbondioxide which is a by-product of this energy generating process is transported by haemoglobin to the lungs for elimination.

11. A: I and III are associated with inhalation/inspiration while II and IV are associated with exhalation/expiration.

12. A: The contraction of the intercostal muscles causes the ribs to move upwards and outwards. This then causes an increase in the volume of the thoracic cage, enabling more air to rush into the lungs (as the pressure drops).

13. D: The process by which the amount of water and solutes in the blood are controlled is known as osmoregulation. 14. D: I is Adrenaline II is Antidiuretic hormone (ADH) IIl is 0estrogen IV is Glucagon

15. A: Adrenaline is the hormone responsible for anxiety.

16. B: I refers to the ear ossicles. These bones are reputed as the smallest bones in the body. They are three in number: . Malleus (Hammer) • Incus (Anvil) • Stapes (Stirrup)

17. D: The outer ear comprises the pinna and the auditory canal. The ear drum is at the junction of the outer ear and the middle ear. The middle ear comprises the ear ossicles and the Eustachian tube. The inner ear comprises the cochlea, the semi- circular canals and the nerves.

18. C: The middle ear is connected to the pharynx by the Eustachian tube (labelled as III). This explains why the Eustachian tube is also known as Pha- ryngotympanic tube.

19. A: The process of fertilization involves the fusion of the nuclei of the male and female gametes.

20. D: • Union of male and female gametes occurs in sexual reproduction, not asexual reproduction. The male gamete will be from the male individual while the female gamete will be from the female in- dividual.

21. A: The skin cell is a somatic cell. The number of chromosomes in the sex cell is always half of that in the somatic cell for a given species. Since P and are sex cells, number of chromosomes in each of them will be ½x 46=23

22. C: The chloroplast is the organelle where photosynthesis occurs. Thus, it can be said that simple sugar is produced in the chloroplast.

23. B: Oxygen is a by-product of photosynthesis. Thus, its release is an evidence for the occurrence of photosynthesis

24. A: The sources of vitamin A include egg, palm oil, carrot sweet potatoes, mango, papaya etc.

25. B: It is food substance L’ that would form a reaction with protease. The shapes of the enzyme and the food substance conform to the lock and key hypothesis.

26. B: Enzymes are specific in their ac- tion.

27. C: Since the enzyme is a protease, the food class it acts on is protein. The end product of digestion of protein is amino acid.

28. C: Clayey soil has a very high ten- dency of becoming water-logged. 45. This blocks root absorption and consequently limit the access to necessary nutrients.

29. C: Leaving the soil bare does not help soil fertility in any way. Instead, it favours soil erosion.

30. D: A group of organisms of the same species living in a particular place is termed population. A collection of organisms of different species living together constitutes a community.

31. A: The part labelled T is the humus. The humus is the organic component of the soil.

32. B: The bottom-most part comprises stones while the penultimate part (IV) comprises sand.

33. D: We have pyramids of energy, numbers and biomass. There is no such thing as pyramid of organisms.

35. D: K is the primary consumer, L is the secondary consumer while M is the tertiary consumer.

36. B: The position occupied by each organism in a food chain is known as the trophic level. NB The position of an organism in its habitat and the role of the organism constitutes the ecological niche of the organisnm.

37. D: An aquatic plant should not have any compelling need for water conservation. Availability of water is not a problem to such a plant.

38. A: The biological association that contributes directly to succession in a community is competition.

39. C: Poaching does not encourage conservation in any way. Instead, it favours the disappearance of the species.

40. A: The burning of farmlands should be discouraged because it destroys the organic components of the soil.

41. B: Since use is made of wood in the manufacture of match sticks, substituting lighter for match sticks is a way of conserving forest.

42. C: Even though AB’ can receive from any blood group, it can only donate to a fellow AB’.

43. C: Skin colour, fingerprint and height are morphological variations while tongue rolling is a physiological variation.

44. A: Blood 0′ has no antigens but it has antibodies ‘A’ and ‘B’.

45. D: The original plants must be or genotypes TT and Tt. Let us check by crossing

46. A: Test cross involves crossing a homo- zygous recessive individual with an organism of unknown genotype to ascertain the genotype.

47. A: Males can only inherit sex-linked traits from the mothers (since the traits are borne on the X-chromosome and a male inherits his only copy of X-chromosome from the mother).

AS = Carrier AA = Normal SS = Sickler. Therefore, Sickler= one out of four = 1/4

49. B: Chameleon exhibits adaptive colouration. Its adaptive colouration is specifically known as camouflage.

50. A: Schizophyte < Thallophyte < Bryophyte < Pteridophyte < Spermatophyte.

NB • Algae (& fungi) are thallophytes • Liverwort is a bryophyte • Fern is a pteridophyte • Angiosperms (and gymnosperms) are spernmatophytes.

THEORY SOLUTIONS

2022 WAEC BIOLOGY (THEORY) 1a (i)The cell is the basic, structural and functional unit of life. (ii) -Theodor Schwann – Matthias Schleiden – Rudolf Virchow

NB: The key organelle responsible for cell reproduction is the nucleus (i) The blood cell that lacks nucleus is the red blood cell/erythrocyte (ii) The absence of a nucleus allows the red blood cell to contain more haemoglobin and, therefore, carry more Oxygen molecules. However, without a nucleus, they cannot divide to make new red blood cells.

– Nucleus – Mitochondria – Chloroplast – Vacuole – Endoplasmic reticulum – Golgi apparatus – Lysosome -Cell wall

c. Milk teeth are the first set of teeth in the growth and development of humans. These teeth are twenty in number. They are later replaced by the permanent teeth.

3a (i) The ecological niche is the position or function of an organism in a habitat. It describes how a species interacts within an ecosystem.

– It provides fruit – It provides firewood – It provides organic matter for soil replenishment – It enhances soil conservation – it has many medicinal applications

– It saves time – It is usually impossible to go and count each species present. Hence, the need for sampling techniques

– Random sampling – Systematic sampling – Convenience sampling – Cluster sampling Stratified sampling

– Arch – loop – Whorl – Compound

4a(i)A conservation law states that a particular parameter of a system does not change as the system evolves over time. (ii)

– Law of conservation of matter – Law of conservation of energy

– Food requirement – For adventure – Medicinal values of some animal parts -Cultural and religion’s views

-Tigers – Rhinos – Gorillas – Elephants – Sea turtles – Amur leopard – African pangolins

– Habitat destruction of wild animals -Climate change – Desertification – Soil – erosion -Flooding

d(i) Blood transfusion is the transfer of blood or a blood component from one healthy person (a donor) toa sick person (a recipient).

(ii) An antigen is a molecule that initiates the production of an antibody and causes an immune response.

– They both have gizzard – They both have pharynx – They both have oesophagus

b(i) Water cycle

-Plants contribute to the water cycle via transpiration – Animals release water into the water cycle when they exhale – Water is also a product of respiration in plants – Animals also contribute to the wate cycle through excretion of waste.

– Xrepresents condensation – Y represents respiration -Zrepresents evaporation.

d(i) Decay is the breaking down of organic matter through the action of some organisms.

– Bacteria – Fungi

– Temperature – Oxygen (aeration)

(iv) Nitrogen cycle

(e) Just like other green plants, carnivorous plants are able to obtain their food through photosynthesis. However, these plants usually grow in areas that are deficient in nitrogen. This is why they trap insects (and other small animals) for nitrogen.

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.

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.

WAEC Biology Past Questions | FREE DOWNLOAD

WAEC Biology Questions – Free WASSCE past questions for Biology.

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.
