B)Life existed on earth from the beginning and we do not know where it came from C)Simple chemicals combined during early stages of earth and evolved into ancestral life form. D)Superhuman powers created life as they exist now and their diversity E) Aliens brought some simple life forms several million...

BIO 311C FINAL EXAM QUESTIONS AND ANSWERS A+ GRADED Define monomers, polymers and macromolecules What reactions happen in condensation synthesis and hydrolysis? 1) condensation synthesis: MAKES polymers by releasing water molecules, condensation synthesis is important in anabolic processes (builds complex from simple) 2) hydrolysis BREAKS DOWN polymers into monomers by adding -H to one molecule and -OH to another (uses n-1 water molecules) while hydrolysis is important in catabolic proc...

BIO 311C QUESTIONS AND ANSWERS A+ GRADED What are the two laws of inheritance? 1. Law of Segregation- Allele pairs segregate during gamete formation and the paired condition is restored by the random fusion of gametes at fertilization. Example: **Monohybrid Cross-(pPxpp) 3:1 ratio after crossing pure bred pea varieties with either spherical seeds or dented seeds. Found that 3/4th of the F2 progenies had spherical seeds and 1/4th had dented seeds. 2. Law of independent assortment- the ...

Bio 311C Unit 3 QUESTIONS AND ANSWERS A+ GRADED How did experiments on transformed pneumonia-causing bacteria and radioactively-labeled bacterial viruses (Hershey & Chase) inform scientists that the genetic material was indeed DNA and not protein? By using certain enzymes that would break down protein, DNA, or RNA, they saw that the genetic make-up would only be altered with DNA Describe the double helix model of DNA, reviewing the evidence that supports this model. What were some speci...
