Which of the following is true of fuel used by the brain? brain cells are able to use several fuels other than glucose. the brain is always the last in line for new fuel. the flow of blood to the brain can be suspended for at least 5 minutes. interruption of blood flow for even a few seconds impairs brain function. the body can modulate blood flow to meet the energy needs of the brain.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
