|
Whats the difference between Biogenesis vs. Spontaneous generation? |

|

What expierment did Francesco Redi design to try to settle the argument of Biogenesis vs. Spontaneous generation? |
He put a slice of meat in a jar and left it there for a couple of days in which maggots appeared. But not everyone was convinced that this proved vital force because some believed flys flew in layed there eggs in the decaying meat and thats what caused maggots to appear. So he ran the experiment again but this time he covered the jar couple days later no maggots appeared. Some people argued that it was because vital force couldn't get in. End result biogensis and spontaneous generation was nethier proved nor disproved. |

|
Who disproved vital force? And what was the experiment performed to do so? |
Louis Pasteur His experment was first he'd started with sterilized broth than he attached a swam neck flask to the beaker so if vital force exsisted it could get in. A few days later there was no microorganisms because they were unable to reach the broth ultimately proving biogenesis. But to futher prove his theory he broke the top off of the beaker and a few days later microorganisms appeared than he tilted the beaker laying it on its side with the swam neck flask and a few days later microorganisms appeared. Showing that life comes from life not death. |

Who was the first to discover handwashing? And how was it discovered? |
Iganz Semmelweis Discovered more pregnant women we're dying in the hospital than by midwife. Turned out most med students handled cadavers right before. So he instructed his students to wash their hands and the death rates of pregnant women in the hospital dropped dramatically. |

Who invented the first vaccine and how? |
Edward Jenner He found that milk-maids who contracted cow-pox were resistant to small pox. So he used cow-pox lesions and injected them into people to innoculate them. |
Vacca=cow |
|
|
Who gave birth to the study of virology and how was it discovered? |
Walter Reed Was the first to discover yellow fever was caused by a virus, not the liquid itself. |
|
|
|
Who could not grow organisms that caused tobacco mosaic disease even when using Koch's postulates? |
Dimitri Ivanowsky Concluded it was a contagious, living, poison (=virus) liquid |
|
|
|
Eukaryotes vs. Prokaryotes |
Eukaryotes: Nucleus, contain organelles, precursor to organisms that eventually formed multicellular animals, majority macroscopic (plants, animals, fungi & protozoa) Prokaryotes: No Nucleus, lack organelles, all microorganisms, older than eukaryotes and also can engage in nearly every activity that eurkaryotes can & many can function in ways eukaryotes cannot |
|
|
