Resource overview
This question paper is listed under Biology in the 2005 examination archive. Its catalogue level is HL. The catalogue session is May. The information below helps you identify the document before opening the complete PDF. Subject, year and session labels come from the archive catalogue; the original cover remains the reference if a label differs. A file is not automatically suitable for your current syllabus simply because its subject name matches.
For revision, choose a manageable section and attempt it before consulting the matching markscheme. Keep a short error log separating knowledge gaps, method choices and unclear explanation. Compare the paper number, level and examination zone before pairing files. Older papers can be useful practice, but their topic coverage and format may differ from the course you are taking now.

Option D Evolution
D1. The water snake (Nerodia sipedon) lives on the mainland surrounding Lake Erie and on the islands
in the lake. The snakes vary in their app earance from banded through intermediate to unbanded.
Recent research has shown that snakes from th e mainland migrate to the islands every year.
Mark-recapture studies on the islands indicate that young snakes which are unbanded have a higher
rate of survival on the islands than do banded snak es. However, banded snakes have a higher rate
of survival than unbanded snakes on the mainland.
Five different populations were studied and the frequency of banded, intermediate, and unbanded
snakes were determined for the two mainland areas (Ontario and Ohio) and the islands of Lake
Erie.
The histograms below show the variation in colour pattern within and between populations.
Category A snakes are unbanded, category B and C snakes are intermediate, category D snakes are
strongly banded.
