Answer:
I would personally recommend taking AP courses for any medical degree. Many colleges or universities consider AP and IB classes to be equal, and unless you are planning to go to college/university out of the US, Advanced Placement classes will be more accepted. Another reason why I would advise against IB classes is that it is not worth it to only take specific classes and is more beneficial to take the full diploma course. Some places will allow you to take individual classes instead of the full program like you would in AP, but it is not a guarantee. AP classes allow you to specialize more and avoid any classes you feel particularly weak in.
Land and water differ into the absorption and releasing of heat, the land heats up quicker than the water, and the land also cools off quicker than the water. So when the air is hotter over the land (during the day), then the air masses are moving from the sea to the land cause they are cooler and heavier. When the air is cooler over the land (during the night), then the air masses move from the land towards the water.
