Massachusetts Comprehensive Assessment System

2015, High School Biology

  Question 32: Open-Response  
An apple contains sugar and starch, which are used by the body when they are digested.
Parts of the digestive system include the following:
  • esophagus
  • large intestine
  • mouth
  • rectum
  • small intestine
  • stomach
  1. List the parts of the digestive system in the order in which the apple passes through them.
  1. Identify one part of the digestive system listed above where mechanical digestion takes place. Explain how the apple is mechanically digested.
  1. Identify one part of the digestive system listed above where chemical digestion takes place. Explain how the apple is chemically digested.
  1. Identify the final product of starch digestion and describe how it is delivered to body cells.

Scoring Guide and Sample Student Work
Select a score point in the table below to view the sample student response.

ScoreDescription
4 The response demonstrates a thorough understanding of how the digestive system converts macromolecules from food into smaller molecules that can be used by cells. The response correctly lists the parts of the digestive system and clearly describes the mechanical digestion and chemical digestion of the apple. The response also correctly identifies the final product of starch digestion and clearly describes how it is delivered to body cells.
4
3 The response demonstrates a general understanding of how the digestive system converts macromolecules from food into smaller molecules that can be used by cells.
2 The response demonstrates a limited understanding of how the digestive system converts macromolecules from food into smaller molecules that can be used by cells.
1 The response demonstrates a minimal understanding of how the digestive system converts macromolecules from food into smaller molecules that can be used by cells.
0 The response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.

Note: There are 2 sample student responses for Score Point 4.
