Sample JAMB UTME Biology 2007 questions

1. Which tissue is chiefly responsible for transporting water and dissolved mineral salts from the roots to the leaves of a flowering plant?
  1. Xylem
  2. Phloem
  3. Cambium
  4. Epidermis

Answer: A. Xylem

Xylem vessels conduct water and mineral salts mainly upward from the roots.

2. In which part of a cell does glycolysis take place?
  1. Nucleus
  2. Cytoplasm
  3. Mitochondrial matrix
  4. Chloroplast stroma

Answer: B. Cytoplasm

Glycolysis is the first stage of respiration and occurs in the cytoplasm.

3. Blood filtration at the beginning of a mammalian nephron occurs primarily in the
  1. Loop of Henle
  2. Collecting duct
  3. Glomerulus
  4. Ureter

Answer: C. Glomerulus

High pressure in the glomerulus forces water and small solutes into the Bowman's capsule.

4. Which sequence correctly shows the pathway of an impulse in a simple reflex arc?
  1. Motor neuron, receptor, sensory neuron, effector
  2. Receptor, motor neuron, sensory neuron, effector
  3. Effector, sensory neuron, relay neuron, receptor
  4. Receptor, sensory neuron, relay neuron, motor neuron, effector

Answer: D. Receptor, sensory neuron, relay neuron, motor neuron, effector

A reflex impulse travels from a receptor through sensory and relay neurons to a motor neuron and then an effector.

5. For red-cell transfusion in the ABO and Rh systems, which blood group is generally considered the universal donor?
  1. O negative
