State the difference between a genotype and phenotype, and then state how you would identify each. that is, where would you look for a genotype or a phenotype

Genotype versus phenotype.

An organism's genotype is the set of genes that it carries. An organism's phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment

to identify the difference

Genotype: take a cat for an example a straight ears or curly ears  its because they have different genos reproducing

Phenotype: A change in the environment also can affect the phenotype. Although we often think of flamingos as being pink, pinkness is not encoded into their genotype. The food they eat makes their phenotype white or pink.

The difference between a genotype and phenotype is that genotype has to do with the gene present in the DNA which is passed from parents to offspring while phenotype deals with phenotypic characteristics which are expressed in physical forms.  

Genotype lies within the DNA and could only be extracted through rigorous experiment while phenotype is easily seen through expression of traits such as skin color, heights among others

Explanation:

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.
