Given in the box below are a set of 14 biological terms. Of these, 12 can be paired into 6 matching pairs. One has been done for you as an example. Identify the remaining five matching pairs. Example: Endosmosis – Turgid cell.
Cushing’s syndrome, Turgid cell, Iris, Free of rod and cone cells, Colour of eyes, Hypoglycemia, Active transport, Acrosome, Addison’s disease, Blind spot, Hyperglycemia, Spermatozoa, Endosmosis, Clotting of blood.
Topic: Matching pairs from a term box
Answer
The five remaining pairs are:
- Cushing’s syndrome – Hyperglycemia
- Addison’s disease – Hypoglycemia
- Iris – Colour of eyes
- Free of rod and cone cells – Blind spot
- Acrosome – Spermatozoa
(ACTIVE TRANSPORT and CLOTTING OF BLOOD are the two terms left over, as the question states that only 12 of the 14 can be paired.)
NOTE THE STRUCTURE FIRST: 14 terms, 12 of which pair up, so TWO are left over. Do not force them into pairs.
THE TWO ADRENAL DISORDERS are the hard pair, and they are OPPOSITES: CUSHING’S SYNDROME — HYPERsecretion of the adrenal cortex, raising blood sugar — HYPERglycemia ADDISON’S DISEASE — HYPOsecretion of the adrenal cortex, lowering blood sugar — HYPOglycemia The prefixes match across the pair, which is the quickest way to settle them: HYPER with HYPER, HYPO with HYPO.
The other three are straightforward once spotted: IRIS — the pigmented curtain that gives the eye its COLOUR BLIND SPOT — where the optic nerve leaves the eyeball, having NO rods or cones, so no image can form there ACROSOME — the enzyme-filled cap on the head of a SPERM (spermatozoa)
STRATEGY for a question of this shape: pair the terms you are certain of FIRST, strike them out, and the difficult ones become obvious by elimination.
