*BIOLOGY JAMB CBT QUESTIONS – ANSWERS & EXPLANATIONS 📚🧠🔥🔥*

*1) B – Mosquito transmitting malaria*
👉 Mosquito acts as a vector, carrying the disease-causing organism.

*2) A – Ability to respond to stimuli*
👉 Irritability means responding to changes in the environment.

*3) C – Tonoplast*
👉 Tonoplast is the membrane surrounding the vacuole.

*4) A – All of the above*
👉 Fossils, homologous structures, and embryos all support evolution.

*5) C – Formation of complex caste systems*
👉 Social insects like ants and bees survive through division of labour.

*6) C – Liver*
👉 The liver aids digestion but is not part of the alimentary canal.

*7) C – Increased genetic diversity within populations*
👉 Evolution increases variation for better adaptation.

*8) A – Presence of chloroplasts*
👉 Plant cells contain chloroplasts for photosynthesis.

*9) C – Savannah grassland*
👉 Savannah has hot summers, warm winters, and scattered trees.

*10) A – Variation in blood pressure among individuals*
👉 Physiological variation affects body functions, not structure.

*11) D – Bones and joints*
👉 These form the framework of the skeletal system.

*12) D – Establishment of marine protected areas*
👉 This helps conserve biodiversity naturally.

*13) A – Robert Hooke*
👉 He discovered cells while observing cork.

*14) C – Lungs*
👉 Gas exchange occurs in the alveoli of the lungs.

*15) C – Pancreas*
👉 The pancreas produces insulin.

*16) B – I and II are correct*
👉 Swim bladder (air bladder) helps fishes float.

*17) C – Heterozygous*
👉 Having two different alleles for a gene.

*18) A – Xylem*
👉 Xylem transports water and minerals.

*19) A – Temperature*
👉 Abiotic factors are non-living components.

*20) C – Fertilization*
👉 It leads to the formation of a zygote.

*21) A – Hibernating during the hottest part of the day*
👉 This reduces heat stress (behavioural adaptation).

*22) D – Habitat*
👉 Habitat is the natural home of an organism.

*23) B – Nitrogen fixation*
👉 Converts atmospheric nitrogen to usable forms.

*24) A – Regulation of body temperature*
👉 Skin helps control heat via sweating.

*25) B – Laterite soil*
👉 Heavy rainfall washes away nutrients.

*26) A – Sexual reproduction*
👉 Involves fusion of male and female gametes.

*27) C – Nitrogen fixation, denitrification, and ammonification*
👉 These recycle nutrients in ecosystems.

*28) D – Organisms produce their own food*
👉 Example: green plants.

*29) C – Species change over time through natural processes*
👉 Core idea of evolution.

*30) C – Testis*
👉 Produces sperm cells.

*31) B – Migration*
👉 A behavioural survival strategy.

*32) B – High muscle tone*
👉 Down syndrome is associated with low muscle tone.

*33) D – Distribution and abundance of individuals within a species*
👉 Focus of population ecology.

*34) C – Carrying capacity*
👉 Maximum population an environment can sustain.

*35) D – Muscular organ that circulates blood*
👉 Main function of the heart.

*36) B – Mutation*
👉 Source of new genetic variation.

*37) C – Red blood cells*
👉 They contain haemoglobin for oxygen transport.

*38) B – Glucose and oxygen*
👉 Products of photosynthesis.

*39) D – Allele*
👉 Alternate form of a gene.

*40) B – Large intestine, appendix, and rectum*
👉 All are part of the alimentary canal.

*41) D – Presence of a segmented body*
👉 Arthropods have segmented bodies and jointed limbs.

*42) C – Implementing sustainable fishing practices*
👉 Prevents over-exploitation.

*43) D – Cells → tissues → organs → organisms → populations → communities → ecosystems*
👉 Correct biological hierarchy.

*44) A – Arteries*
👉 Carry oxygenated blood away from the heart.

*45) C – Genetics*
👉 Study of inheritance.

*46) C – Temperature*
👉 Major factor affecting organism distribution.

*47) D – Sporulation*
👉 Common in plants and fungi, not animals.

*48) A – Fungi absorb organic matter*
👉 They are heterotrophic.

*49) C – Offspring develop inside the female*
👉 Example: humans.

*50) C – Domain*
👉 Highest and most inclusive level of classification.
