Answer:
A stream in a bedrock valley located 5000 feet above ultimate base level that is draining a mountainous region in the headwater of a stream system would have a _____.
high gradient, and a narrow and shallow channel with no floodplain
Explanation:
A bedrock valley has no alluvium mantling the bedrock over which it flows. Alluvium (consists of sand, gravel, silt, clay, and gravel, as well as other organic matters) mantlings or coverings are usually developed in the lower part of the river with the formation of floodplains and deltas. They may also be deposited at lakes or river banks. Headwater streams deliver nutrients and other organic materials (e.g. fallen leaves) to downstream regions to sustain downstream aquatic life.
Answer:
A feature of the reduction in death rates has been the increased excess mortality of males. There have also been big and rapid reductions in death rates in many developing countries, even in the absence of important improvements in living standards. Antibiotics and insecticides have made a major contribution to this movement in the last twenty years. It is unlikely that death rates will fall as rapidly in the next few decades as in the recent past in either developed or developing countries.
It doesn't sound important
B is the best answer.
I hope this helps! :)
