c removing salt and minerals
the process of desalination removes salt and minerals so water is safe to drink
A Biomass
This is because it is easily replenished naturally and over a short period of time but only if there is a large quantity of biomass available. If there is little biomass than it will be nonrenewable.
Answer:
By evaluating opposing arguments, scientific claims can be examined and strengthened.
Explanation:
The purpose of argument is to establish a better, more accurate conclusion. This is demonstrated in the given scenario: because there is disagreement, scientists work hard to find conclusive evidence towards one point or another.
Why not B: It doesn't really depend on conflicting data, though a bigger sample size and more groups helps to get a wider representation. You want your results to gradually converge.
Why not C: This is so untrue! Disagreement is key to healthy discussion and honing down scientific points.
Why not D: Two scientists can disagree; this doesn't flat-out disprove hypotheses. What it does is cast light on their discrepancy and lead them to improve their conclusions or do more research.
Answer:
The atmospheric oxygen initially came from the water molecule
Explanation:
Condition on the primitive Earth , about 4 billion year ago were such which favored chemical evolution. . When the temperature of the Earth was less than 100 degree Celsius. Its atmosphere had nitrogen in the form of ammonia, carbon in the form of carbon dioxide and oxygen in the form of water vapour. There was no free oxygen available and so the atmosphere was reducing.
Then spontaneously biomolecules originated which further gave rise to protobionts. These protobionts evolved into several unicellular organisms among which one was cyanobacteria.
Cyanobacteria are considered as the organisms which added the first molecule of free atmospheric oxygen into the atmosphere. They carried out photosynthesis and split the water molecules to release oxygen as the bye product of the process.
Answer:
its good
Explanation:
the can evaporate and make clouds which cause rain which can water plants
