Five groups of students in mr. walker's science class performed an experiment to determine the effect of salt on the boiling point of water. each group dissolved 5g of salt in 100ml of distilled water, heated the solution and recorded the boiling point with a thermometer that had divisions of 0.1â°c.
each group obtained exactly same boiling point for the salt solution, 100.8â°c. are the results valid?
a) no, because too little salt was used.
b)no, because it was not a controlled experiment.
c)yes, because each group obtained the same results.
d)yes, because the thermometer had divisions of 0.1â°c.

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles
