Answer:Their inferences are based on evidence that they collect during their investigations. Readers learn that scientists gather and interpret evidence and draw conclusions based on this evidence. Some scientists investigate things that they cannot observe directly.
Explanation:
I would go for B, because it is informing other scientists that could've been working on the same subject that here is a possible solution
Eukaryotes have nucleus and protaryotes have plant calls that’s the difference

of the Earth due to the Sun's rays causes convection currents of air
upwards. The warm air moves upwards, while cool air from nearby regions
fills in the lower areas.
Heating of the Earth can cause warm water currents that flow from hot
areas like near the equator and tropical areas, while cold water
currents flow from the arctic and antarctic regions and the temperate
regions.
Areas closer to water bodies have a moderating effect. In the morning
the cool sea breeze comes over the land and keeps the temperature lower
than it would have been as the Sun rises up. In the evening, the warm
sea breeze comes in over the land, and thus the night temperature is
higher than it would have been when the sun has set.
Mountains cause rain carrying heavy dark clouds to rise up, and pass
over it. As a result of this, the clouds tend to precipitate and shed
the water as rain on the Mountain slopes. These form streams and rivers,
and continue to flow usually throughout the year. </span>
