Answer:
A question is developed from some observations and the hypothesis is a tentative explanation for that
Explanation:
First they don't use oxygen, plants use the CO2 in the air and release oxygen out into the air after the plant used up the CO2
Answer:
Increase in biomass
Explanation:
All the other choices have attributes that influence the density property of water except biomass. Biomass is organic material/ matter that is mainly carbon-based – mainly derived from plants and animals. This has no relationship to water density even when the biomass is in the water because it's only gets suspended like sediment and does not get dissolved in the water.
There is no such thing as pure water, when you buy bottled water you think you're buying pure water but it's the same water.
I'm not going into the scientific facts here but the truth is 'pure' water does not exist because that means the water will have NOTHING in it which means they will have to remove the natural minerals and then the water will interact with any organic materials the water encounters, including air and plastic.
<em>But the water is clean and healthy to drink. Just not pure.</em>
