AP Biology Final Exam Review emergent properties - new properties that emerge with each step upward in the hierarchy of life, owing to the arrangement and interactions of parts as complexity increases negative feedback - a mechanism of response in which a stimulus initiates reactions that reduce the stimulus positive feedback - a physiological control mechanism in which a change in a variable triggers mechanisms that amplify the change inductive reasoning - reasoning based on observe...

My document provides a complete summary of the A2 Topic of Cellular control for OCR A level Biology. Within this document, you will find the following subtopics; Mutations, Transcriptional Regulation, Splicing, Post Translational Modification, Hox/ Homeobox Genes, Apoptosis.

28) Humans have 23 pairs of chromosomes, and chimps have 24 pairs of chromosomes. What is the most likely explanation for these differences in human and chimp genomes? A) The common ancestor of humans and chimps had 24 pairs of chromosomes. During human evolution, two human chromosomes fused end to end. B) In the evolution of chimps, new adaptations resulted from additional chromosomal material. C) At some point in evolution, human and chimp ancestors reproduced with each other. D) Errors in...
