Determine whether the following statements about sympatric speciation are true or false. a. Sympatric speciation only occurs in areas where there is local variation in environmental resources. b. A dam dividing a fish population could lead to sympatric speciation.

The true statement is - Sympatric speciation only occurs in areas where there is local variation in environmental resources

Explanation:

Sympatric speciation means the evolution of new species from an ancestor species which are occupying in the same area and no geographical barrier takes place. Overlapping of ranges takes place to the organism and old and new        species are living i the same geographical region.A dam diving a fish population could lead to allopatric speciation where geographical barrier causes formation of new species which are completely different from their ancestor species.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
