Problem 10 - Biology: The Dynamic Science

Question

An example of a digestive specialization is seen in: a. the long intestines characteristic of herbivores. b. the incisors being the dominant teeth in wolves. c. the canine teeth being the dominant teeth in deer. d. salivary lipase being made by humans. e. cellulose being made by humans.

Step-by-Step Solution

Answer

The correct answer is: 'the long intestines characteristic of herbivores'.

Step 1: Analysis of Choices and Comparison with Digestive Specializations

Each option needs to be analyzed in the context of 'digestive specialization'. Digestive specialization refers to adaptations in the digestive system that allow different species to digest their specific diets effectively. a. Long intestines are a digestive specialization in herbivores, enabling them to break down plant material and extract important nutrients. b. Incisors being the dominant teeth in wolves are not specifically related to digestion but more to food acquisition, they use these teeth primarily to catch and kill prey.c. The canine teeth being the dominant teeth in deer is incorrect, as deer are herbivores and do not have dominant canine teeth. d. Salivary lipase being made by humans is not a digestive specialization, it's a common feature in many animals for the digestion of lipids. e. Humans making cellulose is incorrect, as humans do not produce cellulose, it is a complex carbohydrate found in plant cells.

Step 2: Selection of the correct choice

Based on the analysis of choices, it can be concluded that the correct answer is the one that correctly illustrates a true 'digestive specialization'. From the given options, the 'long intestines characteristic of herbivores' signifies such an adaptation. This length allows for extended digestion time, enabling the breakdown and absorption of nutrients from plant matter.
