Maria and Sam are studying about cells, tissues, organs, and organ systems in the human body. This is a picture of the human digestive system. Each part is a different color. Each part does something different during the process of digestion.
Even though each part of the digestive system is different, each part is also alike. What is one thing that each part shares with the others?
A) Each part contains organs.
B) Each part of the system is made of cells. *my answer*
C) Each part breaks down food into smaller pieces.
D) Each part of the digestive system is made of exactly the same cells.
agree
oki ty. :p
@Anvil is correct trust them
The correct answer is B) Each part of the system is made of cells.
To arrive at this answer, let's analyze the given options:
Option A) Each part contains organs. While it is true that each part of the digestive system includes organs, not all parts of the digestive system are the same. For example, the mouth contains the tongue and teeth, while the stomach contains the gastric glands. Therefore, this option does not fit the statement that each part is alike.
Option B) Each part of the system is made of cells. This option is the correct answer. Cells are the building blocks of all living organisms, including humans. Each part of the digestive system, such as the mouth, esophagus, stomach, and intestines, is composed of cells.
Option C) Each part breaks down food into smaller pieces. While it is true that each part of the digestive system plays a role in breaking down food during the process of digestion, not all parts specifically share this characteristic. For example, the mouth breaks down food mechanically by chewing, while the stomach breaks it down chemically using enzymes. Hence, this statement is not accurate for all parts of the digestive system.
Option D) Each part of the digestive system is made of exactly the same cells. This option is not correct. While all parts of the digestive system are made up of cells, these cells are not exactly the same. The cells in different parts of the digestive system have specialized functions and structures that enable them to carry out their specific roles, such as absorbing nutrients or secreting digestive enzymes.
Therefore, option B) Each part of the system is made of cells is the most accurate and suitable answer to the question.
