Paleoclimatologists study ice cores to investigate Earth’s past climate. They use methods such as oxygen isotope analysis. Which feature inside the ice are the scientists interested in analyzing and why? A.
They search for the geological layer at which ice turns to water, which is an indicator of past precipitation data.
B.
They seek single-celled microorganisms deep within the ice to assess the efficiency with which they processed oxygen.
C.
They study air bubbles trapped in the ice, comparing their chemical composition between past and present.
D.
They build a temperature and albedo profile of ice and water samples to predict when and where climate change is eminent.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'

elements make up everything, and they combine to make compounds.

the answer is c

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
