Answer:

Ice cores are cylinders of ice drilled from ice sheets/glaciers. ice cores tell scientists about temperature, volcanic activity, atmospheric composition, precipitation, and wind patterns.

Explanation:

the thickness of each layer in the core allow scientists to determine how much snow fell in the area during a particular year. the layers are formed by layers of different types of snow. During the summer, when it is light for 24 hours, the snow on the top layer changes texture. When winter arrives, it turns dark and cold again and more snow falls on top of the summer snow, creating distinct layers.

Hope this helps!

Answer:

The correct answer is C. helps process explicit memories for storage.

Explanation:

The hippocampus is an structure of the brain and is located inside the temporal lobe. The main function of the hippocampus is to mediate the generation and recovery of memories in conjunction with many areas spread across the cortex and with other areas of the limbic system. It helps to process and recover the episodic memory (those related to events) and spatial memory (mode in which we perceive space or dimensions). This organ is also where short-term memories become long-term memories, that is, it acts as a mediator of memories, acting as an activation node that allows different memories distributed across different parts of the brain to be activated.

iVinArrow [24]
Well everyone's needs for love and attention are different. It can depend on how you were raised, if you received a lot of attention as a kid, etc. Humans are social creatures so we already crave human interaction. and, going back to how you were raised, even if you were raised quite well and you got enough attention as a kid, it really depends on how people treated you and maybe how many times you've had your heart broken or something along those lines. That need honestly varies from person to person. But I know how it feels, you'll get through it, you'll be okay.
