Why study cellular and molecular biology? - Answer The connecting basis of all life is at the cellular and molecular level. DNA, RNA, proteins and the cellular mechanisms behind each of these form the fundamental basis of life. Many biological phenomena are better understood at the biochemical and molecular level. What are the 8 emergent properties of life? - Answer Reproduction Growth and Development Order and Structure Metabolism Respiration Response to environmental stimuli Ada...

BIO 311C FINAL QUESTIONS AND ANSWERS A+ GRADED Two black guinea pigs were mated and they produced 14 black and 6 white offspring. Based on the results what are the genotypes of the parent pigs? A) Homozygous dominant B)Heterozygous dominant C) Homozygous recessive D) Heterozygous recessive E) Hemizygous dominant B)Heterozygous dominant almost 3/4 of offspring were black so this is the dominant trait and since white offspring occurred (~25%) we know that the parents must both h...

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 ...
