E. It takes a picture of the brain according to oxygen levels. More oxygen in an area indicates more activity in that area.
Explanation:
Haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated. This distinction in magnetic characteristics leads to tiny variations in the blood MR signal. Since blood oxygenation differs, these variations can be used to identify brain activity depending on the concentrations of neural activity.
Answer: Independent Variable
Explanation: Already explained this one in another post.
Answer:
large grain sizes, more precipitation, warmer temperatures.
Explanation:
Soil is the thin layer of material covering the earth's surface and they are usually formed through the process of weathering of rocks. The soil consists of mainly mineral particles, organic materials, air, water and living organisms and they interact with each other.
Large grain sizes, more precipitation, warmer temperatures are the factors that increase the rate of soil formation.
This is true. it is called origin.
