Using mendel's flower color purpple is dominant, white is recessive, if two heterozygous plants are crossed, what is the probability that the first two offspring will have purple

The answer is 50%.

Explanation:

According to the question, using mendel's flower color, if two heterozygous flowers one with the dominant color purple and one with the recessive color white, the probability that the first two offspring to have purple flowers is 50% because both parent flowers are heterozygous.

I hope this answer helps.

b. heterotroph

explanation:

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.
