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 ...

How long ago did life start on Earth? What does the timeline look like? - Answer -Life started 500 million years after Earth's formation Bacteria -> Archaea -> Protists (unicellular) -> Protists (unicellular) -> Plantae -> Fungi -> Animalia Miller and Urey's experiment and basic results... - Answer -Experiment: used basic molecules (H, H2O, methane, ammonia) in a setup w/ high power electrodes to stimulate energy. Noticed that simple sugars, amino acids, and ...

BIO 311C QUESTIONS AND ANSWERS A+ GRADED Reconstruct the major timelines in the origin and evolution of life on earth in a logical sequence but no need to memorize the specific times. earth formation (4.5 bya) - bacterial fossils (4.0 - 3.5 bya) - cyanobacteria (2.5 bya) - unicellular eukaryotes (1.5 bya) - multicellular eukaryotes (1.0 bya) - humans Interpret Miller and Urey's experimental setup They used H. H20, methane, and NH4+ in a setup with high power electrodes to simulate ligh...

Bio 311C Final QUESTIONS AND ANSWERS A+ GRADED A suspension of algae is incubated in a flask in the presence of both light and CO2. When it is transferred to the dark, the reduction of 3-phosphoglycerate (3PG) to glyceraldehyde 3-phosphate (G3P) is blocked, and the concentration of ribulose 1,5-bisphosphate (RuBP) declines. Why does the RuBP concentration decline? A) RuBP is synthesized from G3P. B) G3P is converted to glucose. C) RuBP is used to fix CO2. D) Both a and b E) Both a an...

BIO 311C ICAS QUESTIONS AND ANSWERS A+ GRADED 1) Which of the following in an anabolic process that is endergonic and endothermic? A) ATP + H 2 O à ADP + Pi B) C 6 H 12 O 6 + 6O 2 à 6CO 2 + 6H 2 O C) CO 2 + H 2 O à CH 2 O + O 2 D) FADH 2 à FAD + H 2 E) CH 4 + 2O 2 à CO 2 + 2H 2 O C) CO₂ + H₂O → CH₂O + O₂ This is an anabolic process (building complex molecules from simpler ones) that is also endergonic (requires an input of energy) and endothermic (absorbs heat). ...

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...
