Health advocates advise that men drink about 13 cups of water daily and women drink about 9 cups daily—with adjustments for activity level. however, they strongly advise against drinking salt water. based on what you have learned about passive transport, explain why they recommend this.

Passive transport is when substances will flow from high to low concentration.  Salt water has a higher concentration than the fluids inside a human.  Therefore, drinking salt water would cause fluids to leave human cells to achieve equilibrium.  As a result, salt water will actually make a person thirstier.

Hope this helps!

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
