Earthworm is one of the most common annelids that we come across. It is a deposit feeder and shows extracellular digestive system consisting of a digestive tract along with the digestive organs. The digestive tract is a specialized tube in which the digestive contents move in one direction from the mouth to the anus. The esophagus, crop, gizzard, and intestine are the common digestive organs found in Annelids, such as the earthworm, insects, such as grasshopper, and birds, such as pigeon (refer Figure 47.4 (A), (B), and (C)).

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

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.
