Which of the following is the minimum level of structure needed to perform the function of waste removal?

A. body system
B. tissue
C. cell
D. organ

C or A

C I should know because i had this on my quiz.

it is a because a cell makes you.

To determine the minimum level of structure needed to perform the function of waste removal, let's analyze each option:

A. Body system: This refers to a group of organs that work together to perform a specific function. While waste removal is a function performed by some body systems, such as the urinary system and the digestive system, it is not the minimum level of structure needed.

B. Tissue: Tissues are groups of similar cells that work together to perform a specific function. Some tissues, like epithelial and connective tissues, are involved in waste removal, but again, it is not the minimum level required.

C. Cell: Cells are the basic building blocks of living organisms. They have specialized structures and functions. In the context of waste removal, certain cells, like epithelial cells in the kidneys and liver cells, play a role in eliminating waste from the body. Hence, cells are the correct answer in terms of the minimum level of structure needed to perform the function of waste removal.

D. Organ: Organs are made up of different tissues working together to perform a specific function. While organs like the kidneys, liver, and intestines are involved in waste removal, they are not the minimum level required.

Therefore, the correct answer is C. cell.
