Which city shown in the climate graphs here, is most likely in the southern hemisphere?

Explanation:

One of the most common ways of showing an area's climate is a climate graph summarising its monthly temperatures and precipitation. The pattern of temperature gives clues about continentality, latitude and hemisphere whilst the pattern of precipitation gives clues about the nature of rainfall, flood risk, drought risk and agricultural possibilities

what bodys are there orbiting?

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
