How well do you understand living things and their vital processes? Whether you are preparing for JAMB, WAEC, NECO and Post-UTME, these Biology past questions and answers cover such subjects as the chemistry of life, botany, evolution, genetics, ecology etc to help you know what to expect, improve your speed and confidence and be really prepared for the actual aptitude test.
Fishes survive in water mainly because they possess
streamlined body
scales
paired fins
gills
Correct answer is D
Gills are specialized respiratory organs found in fish that allow them to extract oxygen from water. While a streamlined body, scales, and paired fins are all essential adaptations for fish to navigate and survive in water, none of them directly relate to the process of oxygen extraction and respiration like gills do. However, without gills, fish would not be able to respire efficiently underwater and would not survive in their aquatic habitats.
The diagram below is an illustration of a cell in which photosynthesis takes place. Study it and answer the question.
In which of the labeled parts would molecules of water and carbon (IV) oxide combine to form sugar?
I
III
II
IV
Correct answer is D
No explanation has been provided for this answer.
Which of the following processes does not occur during photosynthesis?
Energy from sunlight is absorbed
Carbon (IV) oxide is evolved
oxygen is evolved
water is split
Correct answer is B
During photosynthesis, carbon dioxide is taken in by the plant, and water is split to produce glucose and oxygen in the presence of sunlight and chlorophyll.
Growth in animals differs from that in plants because growth in
plants is indefinite
plants is intercalary
animals is apical
plants is from within
Correct answer is A
Growth in plants is indefinite: Unlike animals, which typically have a determinate growth, many plants exhibit indeterminate growth, especially in their early stages of life. Indeterminate growth means that plants can continue to grow throughout their lives, adding new tissues and expanding in size as long as favorable conditions are present.
