SECTION A
QUESTION 1
1.1 Answer the following multiple-choice questions by choosing the most
appropriate answer. Write down only the letter of your choice. Example
1.1.11 A
1.1.1 Which one of the following will be ABSENT during asexual reproduction?
A Propagation of new plants.
B Formation of a zygote.
C Formation of spores.
D All of the above.
1.1.2 The diagram below represents two species of bacteria grown on Petri
dishes. The strip in the middle of the dishes contains the antibiotic
penicillin applied to the strip in a gradient of concentrations, i.e. from high
to low concentration.
Which one of the following statements is TRUE?
A The minimum concentration of penicillin required to inhibit the growth
of species X is approximately 800 units.
B If 900 units of penicillin was applied to a Petri dish containing both
Species X and Y, eventually Species X would occupy all of the Petri
dish.
C Species X is less resistant to penicillin than Species Y.
D Species X replicates faster than Species Y, thus occupies a greater
area than species Y in the presence of penicillin.

, 1.1.7 Structure that transports fats away from the intestines:
A Capillaries
B Lacteal
C Arteries
D Veins
1.1.8 Seed producing plants are...
A spermatophytes
B angiosperms only
C gymnosperms only
D gymnosperms and pterophytes.
1.1.9 Which of the following characteristics is unique to the Arthropoda phylum?
A Segmentation
B Closed circulatory system
C Exoskeleton
D Radial symmetry
1.1.10 When an infection was treated with a new drug, the inflammation
decreased. In a few patients the inflammation increased after one week.
A probable reason for this could be that …
A the patients developed an allergic reaction to the drug.
B the decrease in inflammation allowed the pathogens to become
resistant to the drug.
C the white blood cells were not functioning properly and therefore the
inflammation returned.
D a few pathogens resistant to the drug were present at the start of
treatment, the drug could not kill them and so they reproduced.
