Answer to Problem 1MC
Correct answer:
The terms gastrointestinal tract, digestive tract, and the alimentary canal are the synonyms.
Explanation of Solution
Explanation for correct answers:
Option (a) is given as gastrointestinal tract. The alimentary canal is one of the main parts of the digestive tract. It is a coiled and hollow muscular tube that continues from the mouth to the anus. The gastrointestinal tract or gut is its synonym. Hence, option (a) is correct.
Option (c) is given as digestive tract. The alimentary canal that continues from the mouth to the anus plays the major role in the digestion of the food material. It is also called the digestive tract. Hence, option (c) is correct.
Option (d) is given as alimentary canal. The alimentary canal is a pathway, through which the food moves from the mouth to the anus during the process of digestion. The terms gastrointestinal tract, digestive tract, and the alimentary canal are the synonyms. Hence, option (d) is correct.
Explanation for the incorrect answer:
Option (b) is given as digestive system. The digestive system is the organ system that consists of digestive tract and the accessory digestive organs. It is not the synonym of the gastrointestinal tract, digestive tract, or the alimentary canal. So, it is an incorrect option.
Hence, option (b) is incorrect.
The alimentary canal that continues from the mouth to the anus plays the major role in the digestion of the food material. The terms gastrointestinal tract, digestive tract, and the alimentary canal are the synonyms.

- PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population?

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_forward
