Which of the following situations are occurring when a red flower (rr) and a white flower (ww) produce a pink flower? a. multiple alleles b. incomplete dominance c. codominance

B. Incomplete dominance

The flower has a pattern of inheritance in which the heterozygous offspring show a phenotype between the phenotypes of the parents (in the middle) which is why the flower is pink.

The best way to tell its true color is to look at the minerals streak

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
