Answer:
Osmosis
Explanation:
Osmosis is the process of movement of water molecules from the region of its higher concentration (hypotonic) to that of the lower concentration (hypertonic).
Here, two solutions of different solute concentration are separated by a membrane that allows the movement of water molecules through it. Osmosis is a passive movement and does not require an input of energy as it is driven by the concentration gradient.
Answer:
The correct answer is "chloroplasts and mitochondria".
Explanation:
Chloroplasts and mitochondria are two essential organelles because of its function of producing Adenosine triphosphate (ATP), the "molecular unit of currency". Chloroplasts are organelles that are found in plants and work in light conditions, whereas mitochondria could produce ATP in the dark. Since the biologist found that the heavier fraction could produce ATP in light it is very likely that it will have chloroplasts, while the light fraction that produces ATP in the dark would likely have mitochondria.
So the answer is evaporation or vaporization. Water vapor can in turn be cooled to form liquid water.
