1.05 assessment by ??????? 1) What does it mean when scientists say that living organisms share a universal genetic code? Genetic code means DNA and when organisms share a univeral genetic code they share a structure of DNA. 2) How does a universal genetic code relate to the hypotheses about the origin of life on Earth?Universal Genetic code would indicate that all organisms descended from a common ancestor‚ seeing how all organsims share a

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

Osmosis Case study You are a veterinarian working in Indooroopilly and return from lunch to find a nurse treating a six year old kelpie‚ Baxter. Baxter is very lethargic‚ has an increased heart rate‚ and when you pinch his skin the fold remains visible. The owner tells you that they knew something was wrong when‚ upon returning to the outdoor car park from a three hour shopping trip‚ they saw Baxter passed out on the back seat. The temperature in the car would have been very high and Baxter

Activities 5. Why do you think stop and start codon signals are necessary for protein synthesis? These are necessary because start codons tells the tRNA to begin translating the codons into proteins and stop codons tell the tRNA to stop translating codons into proteins. They are essential in the process of producing proteins. 6. Describe the processes of transcription and translation in your own words‚ based on what you have observed in the Gizmo. Transcription: Protein synthesis process starts

Biology Midterm Outline Topics: * Topic One: Chemistry of Living Things (p2-4) * Topic Two: The Cell (p5-6) * Topic Seven: Evolution (p23-27) * Topic Ten: State Labs (37-40) Topic One: Chemistry of Living Things I. All living things must maintain homeostasis in order to stay alive. A) Homeostasis: A balanced state in an organism’s body. B) Failure to maintain homeostasis results in disease or death. C) Homeostasis is often maintained using feedback mechanisms. 1. Feedback mechanisms

I am very good at Biology as it is the main subject required for this course and have a good understanding on a cellular level of organisms (plants and animals). I am a negotiator and prefer to work in teams‚ paying close attention to everyone’s opinion and making decisions accordingly. I have studied all three sciences at school level and because Biology was the subject I was very much interested in is what has compelled me to pursue a career in a Biology related field. At level 3 I am
