PLEAASE PLEASE HELP ME!!! I'm failing science and he gave us this test to do. PLEASE HELP. I'll give lots of points You are tasked with investigating the sudden die-off of salmon in a river in Washington State. The salmon were trying to swim upstream to spawn but died near or just past a dam about halfway along the river's path.

You observe that numerous area farms apply atrazine to their crops at this time of year and that the one dam does employ methods for allowing salmon to move upstream past it.

The water quality data you collected include:

- high levels of sediment at one location near the middle of the river's path by the dam

- low levels of the toxin atrazine at some of the upstream testing locations along the river

- very low levels of dissolved oxygen along the entire downstream half of the river due to recent algae buildup

Which type of water pollution seems MOST LIKELY to have contributed to the sudden death of the salmon and why? Include a description of your chosen type of water pollution.

integrated circuit (ic) is defined as a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. a functional electronic circuit requires transistors, resistors, capacitors, inductors, etc., and the connections between them.

allowed for the prediction of the properties of missing elements.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
