EXPECTED QUESTIONS FROM THE ENTIRE 2024 IJMB BIOLOGY SPECIMENS

I. Identification of specimens with or without reasons (it will be stated) take note.

II. classification of the specimen

III. characteristics of the specimen (class characteristics) take note:

IV. T.S, L.S or lateral view of the specimen (drawing of possible specimens) takes note.

V. Materials consumed by specimens (mode of feeding)

VI. adaptive features of the specimens

VII. economic / uses of the specimen

VIII. pest of the specimens

IX. Method of propagation of specimen (plants specimens only) takes note.

X. types of morphological modification (plants only)

XI. pigmentation found on a specimen (plants only)

 

Adaptive features of specimen E

  2. Hollow and light bone
  3. High metabolic rate for rapid energy
  4. production
  5. A keen vision for efficiency
  6. Possessions of highly body weight to ease flight.
  7. Presence of air sac
  8. Streamline body shape

Types of flight in specimen E.

  • Gliding
  • Hopping
  • Steering

 

Functions of feathers in specimen E.

  1. For flight
  2. Regulation of body temperature
  3. Acts as insulation

Materials specimen E feed on.

  • Smaller insects
  • Grains e.g. millet
  • Cereals
  • Grasshoppers

Functions of beaks in specimens E

  1. For feeding
  2. Killing the prey
  3. Feeding young once

 

Class characteristics of species E.

  • Absence of teeth
  • Fore limbs are modified into feather
  • Respiration is by lungs

ECONOMIC IMPORTANCE OF SPECIMEN G

  1. Wood is extensively used for low-cost furniture, floor, ceiling boards, window frames, heavy packing cases, match splints, brush backs, oar blades, agricultural implements etc.
  2. Also suitable for tea chest plywood. A hard charcoal of high calorific value is obtained from mango wood.
  3. After preservative treatment, it can be used as a substitute for teak as beams, rafters, trusses, and door and window frames.
  4. Suitable for slate frames, ammunition boxes, bobbins, carving and turnery work.
  5. The bark possesses 16% to 20% tannin l and has been employed for tanning hides.
  6. It yields a yellow dye, or, with turmeric and lime, a bright rose-pink.
  7. The bark contains mangiferine and is astringent and employed against rheumatism and diphtheria in India.
  8. The resinous gum from the trunk is applied on cracks in the skin of the feet and on scabies, and is believed helpful in cases of syphilis.
  9. Mango kernel decoction and powder (not tannin-free) are used as vermifuges and as astringents in diarrhoea, hemorrhages and bleeding hemorrhoids.
  10. The fat is administered in cases of stomatitis.

 

ECONOMIC IMPORTANCE OF SPECIMEN I

  1. Its nut, also known as cashew, is commonly eaten as food.
  2. People also use the nut to make medicine.
  3. Cashew is used for stomach and intestinal (gastrointestinal) ailments.
  4. Some people apply cashew directly to the skin as a skin stimulant and to seal (cauterize) ulcers, warts, and corns.
  5. Cashew contains chemicals that might work against certain bacteria.

 

Classification of specimen J

Kingdom = plantae

Subkingdom = tracheophata (vascular plants)

Division = spermatophata ( seed plants)

subdivision = angiosperm ( flowering plants)

Class = magnoliopsida or dicotyledonous.

 

BOTANICAL NAME OF SPECIMEN J: Abelmoschus esculentus.

MODE OF PROPAGATION OF SPECIMEN J : mainly by seed

TYPE OF PLACENTATION IN SPECIMEN J: Axile placentation.

DIFFERENCES BETWEEN SPECIMEN J AND SPECIMEN H

  • Tomato’s seeds are numerous while mango has only one seed.
  • The endocarp of tomato is edible while that of mango isn’t.
  • The mesocarp and endocarp of tomato are fused together while that of mango aren’t.SPECIMEN K(clayey soil).

PROPERTIES OF SPECIMEN K

  1. It have a great affinity for water,i.e it retain water better than other materials.
  2. It have small particle sizes .
  3. They are denser than other soil types.
  4. It can be molded into different shapes when wet.

NB. There is no time, read on clayed and sandy soil. I will send the full manual to my 2024 ijmb Biology specimens Group.
