6. Based on the information provided in this reading, what is the best conclusion that can be reached?
A. Human activity is the cause of increasing global temperatures.
B. Increased CO, concentrations are the only cause of increasing global temperatures.
C. Past and present data show a trend in increasing Co, concentrations.
D. There is nothing that can be done to reduce global temperatures.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

i would say b

explanation:

but i think i would need more information than that

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
