Concept explainers
a.
To determine: The possible method to handle the scenario in which an individual should contact the proband beforehand to explain the results and the implications of the results.
Introduction: A couple has undergone a prenatal test in which the young woman (proband) is found to have the sickle cell trait (Ss), and her partner does not have the sickle cell anemia (SS). The woman’s family has a family history of sickle cell anemia. Their prenatal tests indicate that the fetus is affected with sickle cell anemia (ss) and the only way it is possible is when the woman’s partner is not the father of the fetus.
b.
To determine: Whether it is appropriate to keep the information from the partner as he believes he is the father of the baby and the other problems related to this case.

- magine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
