• Prophase > Prometaphase > Metaphase > Telophase

• Anaphase > Prometaphase > Prophase > Metaphase > Telophase

• Interphase > Prophase > Prometaphase > Metaphase > Telophase

• Prometaphase > Prophase > Metaphase > Anaphase > Telophase

What process do organisms use to import large macromolecules?

• Exocytosis

• Endocytosis

• Diffusion

• Active transport

All of the following describe features of biological membranes EXCEPT:

Which of the following represents the conditions of early Earth?

• Low levels of hydrogen; High levels of oxygen, methane, ammonia and water vapour

• Low levels of oxygen; High levels of hydrogen, methane, ammonia and water vapour

• Low levels of hydrogen, methane, ammonia and water vapour; High levels of oxygen

• High levels of hydrogen, methane, ammonia, water vapour and oxygen

RNA is a polymer made out of which of the following monomers?

• Amino acids

• Nucleotides

• Fatty acids

• Simple sugars

A study observed that a parent and its offspring all had blue eyes, as opposed to the brown coloured eyes commonly seen in the population. What feature of mutations does this study provide the best evidence for?

• The individuals acquired the blue-eye mutation due to errors in the proofreading of DNA

• The individuals acquired a beneficial mutation

• The mutation occurred in the gametes

• The mutation occurred in somatic cells

If a random mutation in one fruit fly results in resistance to a specific pesticide, how would this lead to resistance in the fruit fly population?

• The mutation makes the insect able to survive and reproduce, passing the mutation onto the next generation

• The mutation allows the insect to ingest more food, enabling it to be healthier than other insects

• The mutation allows the insect to avoid predation

• The mutation enables the insect to be better camouflaged than other insects

Which of the following is not a direct observational evidence for the Theory of Evolution?

• Galapagos Finches evolved different beak sizes and shapes to utilize different food resources

• 6 fish species contained the same intron 6 to LDH-A gene with slight modifications

• Artificial selection produced domestic dog species from the common wolf ancestors

• Antibiotics initially killed almost all bacteria, but survivors were resistant and passed on antibiotic resistance to successive generations

Palm trees have an average height of 7 metres. After several generations of disruptive selection, how tall will majority of the palm tree population be?

• 7 metres

• <7 metres AND >7 metres

• <7 metres OR >7 metres

• 3.5 metres

Which of the following correctly labels the cladograms?

• I – Monophyletic; II – Paraphyletic; III – Polyphyletic

• I – Monophyletic; II – Polyphyletic; III – Paraphyletic

• I – Paraphyletic; II – Monophyletic; III – Polyphyletic
