One of the traits Gregor Mendel studied was flower color in pea plants. Mendel found that purple color factor was dominant to white color factor. Now, we know that Mendel’s factors are genes, or alleles.

An illustration of two generations of plants labeled the F1 and F2 with all purple flowers in the F1 and ¾ purple and ¼ white in the F2 generation.

Look at the F1 generation produced when two parent plants are crossed. Then, look at the F2 generation produced when two F1 plants are crossed. What can you infer about the original parents’ genotype and phenotype? Choose the 2 statements that apply.

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
