Textbook Question
Chapter 10, Problem 42RQ
The relationship between focal length (F) of a lens, object distance (P), and image distance or focal point (Q) is 1/F = 1/P + 1/Q. Assume the distance from lens to retina is 20 mm.
- (a) For a distant object, P = infinity (∞) and 1/∞ = 0. If Pavi sees a distant object in focus, what is the focal length of her lens in meters?
- (b) If the object moves to 1 foot in front of Pavi’s lens and the lens does not change shape, what is the image distance (1 in. = 2.54 cm)? What must happen to Pavi’s lens for the closer image to come into focus?

Svp je voulais demander l aide pour mon exercice
Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer.
Write a 1,050- to 1,225-word memo to your colleague.
Include the following in your memo:
An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences
A description of the processes of transcription and translation
An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand
Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder:
Does AML run in families?
What genes are tested for?
Respond to the following in a minimum of 175 words:
What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly?
Provide an example of how you might explain these consequences in terms that patients might understand.
