Jand k want to have a baby, but they are a little concerned because they both have the sickle cell trait. they want to know what the possibility is that their child may actually have the disease.

1. develop a punnett square depicting the possibility that their offspring will have the trait and/or the disease.

2.how would the nurse interpret this punnett square?

Sickle cell anemia is an autosomal recessive disorder. For the trait to occur, both of the alleles in an individual should be recessive. Parents who both have sickle cell anemia will have 100% results for their children to carry the disease. The results can be depicted from the following punnet square:

       s               s

s     ss              ss

s      ss             ss

The results will be interpreted by the nurse as having 100% chance for the parents to have the child born with sickle cell as both the parents carry the disease  which is autosomal recessive.

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.
