(02.03 LC) How has the discovery of 5,300-year-old Ötzi, the Iceman, helped scientists in their knowledge? (4 points)
Ötzi, the Iceman, was as old as previously thought.
Ötzi, the Iceman, existed at a time when the climate was warm.
Precise knowledge about his food and clothing is available.
Humans from that period are exactly same as modern humans.

the denominator has a very specific role.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
