Draw these things in a Punnett Squares for biology.

1. A black mouse with a short tail (BBll) is mated with a brown mouse with a short tail (bbll). What proportion of there offspring will be black with short tails?

2. A tall, purple-flowered pea plant (TTPP) is crossed with a short, purple-flowered pea plant (ttPp). What proportion of the offspring will be heterozygous fort flower colour? What proportion of the offspring will be tall with wight flowers?

Explanation:

the dark variety, as they are not visible on the dark tree barks

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.
