nova: origins part II- how life began
if earth was into 24 hours how long would humans have been around
30 seconds
how are ancient rocks tested to see if life existed at that time
a piece of the rock is extracted and analyzed to look for carbon
what was found in the meteorite that hit australia
amino acids
snotties
bacteria formed into snotty/gooey drips
how did the moon form
because of the crash between it and earth
four elements that make up life
carbon, nitrogen, hydrogen, oxygen
what element is so important and why
carbon- because of its bonds
found in the volcanic vents were what
creatures of all types (microbes)
recipe for creating life
dirty garment and wheat in a vessel
stanley miller experiment
filled up tubes with gas, water, electric charge and amino acids were produced
what happened to waste gas after ocean absorbed it
formed with iron to make iron ore
gas present in cueva de villa luz (cave)
hydrogen sulfide
if life excited during the collusion of the "moon" and earth what would have happened to the building blocks of life
it would have been destroyed
peptides make what
make up the cells in our body
cyanobacteria
microscopic blue green bacteria using photosynthesis to provide nutrients
in the outer atmosphere whats found in the space dust
organic molecules
waste gas produced by what bacteria
oxygen
bacteria and oxygen were so important because of what
oxygen protected life by creating a layer of ozone & bacteria was important to be able to breathe
amino acids are the building block of what
proteins and cells
gas in cueva de villa luz (cave) smells like what
rotten eggs
stromatolites
solid structure created by single-celled microbes called cyanobacteria
earth today
stronger sun, thiner atmosphere, green blue color
hydrogen sulfide and water form into what
sulfuric acid
simulated collusion experiment
the amino acids transformed into peptides and changed from a clear color to a brown color
composition of atmosphere change as the bacteria grew how.
there was an growth in oxygen.
what are bacteria underground using as energy
water and other chemicals
ancient earth
weaker sun, thicker atmosphere, red brown color
heavy bombardment
when comets and meteoroids kept pounding the earth
