ACID RAIN
When sulfur dioxide (SO2) and nitrogen oxides (NOx) are
released into the atmosphere, they react with water, oxygen,
and other substances to form mild solutions of sulfuric and
nitric acid called acid rain. The solutions can be spread
across the atmosphere over hundreds of miles. When acid
rain reaches Earth, it flows across the surface in runoff
water, enters water systems, and sinks into the soil.
5. Which of the following is NOT an effect of acid rain?
A. essential nutrients that are needed by organisms are eliminated from soil
B. aluminum released into the soil increases the trees ability to take in water
C. plants are less able to withstand cold temperatures, insects, and disease
D. increased toxicity of the water that is used by aquatic animals and organisms.

Cold case files recently began re-investigating an old murder case. the murder took place in the park; a young man, james, was hit over the head with a brick and killed. police suspected the jealous former boyfriend of james' wife, karen. whoever killed james may have washed their hands in a near-by bird bath as detectives found blood in the bird bath. since the murder took place before dna fingerprinting was available, the suspected killer, ronnie, went free. detectives are now reviewing the blood evidence using dna fingerprinting. based on the dna fingerprints of all possible suspects, who is james' killer?
