Biology Introduction

My name is Chiara Miani and i am looking to find someone who can write a Biology introduction of 1000 words. In this introduction i would like to talk about different proteins and what they do ( Transferrin, hemoglobin, cytochrome c, Myoglobin, CD4, Serotonin receptor and Tubulin alpha 1B chain) as well as a definition on what vertibrates are. I would also like the molecular clock to be explained as well the different uses for the molecular clock and time periods.
