Textbook Question
Chapter 26, Problem 9TYU
FOCUS ON INTERACTIONS
Giant lycophyte trees of Earth’s early forests (see Figure 26.30) had microphylls, whereas ferns and seed plants have megaphylls. Write a short essay (100-150 words) describing how a forest of lycophyte trees may have differed from a forest of large ferns or seed plants. In your answer, consider how the type of forest in which they grew may have affected interactions among small plants growing beneath the tall ones.

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.
