Question

  1. which statement represents a correct organizational relationship in living things?

a. organs make up cells and cell make up atoms
b. atoms make up tissues and tissues make up cells.
c. cells make up organs and organs make up tissues.
d. cells make up tissues and tissues make up organs.

  1. an organ system is a group of organs that work together to support which of the following?

a. ecosystem
b. molecule
c. organism
d. tissue

Explanation:

Response
Question 3
Brief Explanations

To determine the correct organizational relationship in living things, we recall the biological hierarchy of organization: atoms make up molecules, molecules make up cells, cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make up organisms.

  • Option A: Organs do not make up cells, and cells do not make up atoms. This is incorrect.
  • Option B: Atoms do not make up tissues directly (they make up molecules first, then cells, then tissues), and tissues do not make up cells (cells make up tissues). This is incorrect.
  • Option C: Cells make up tissues (not organs directly), and organs are made up of tissues (not the other way around). This is incorrect.
  • Option D: Cells group together to form tissues, and tissues group together to form organs. This follows the correct biological hierarchy.
Brief Explanations

An organ system is a group of organs that work together to perform a specific function. The level of biological organization above organ systems is the organism.

  • Option A: An ecosystem consists of multiple organisms and their environment, so organ systems do not support ecosystems directly.
  • Option B: A molecule is a much lower level of organization (below cells), so organ systems do not support molecules.
  • Option C: Organ systems work together to support the survival and functioning of the entire organism. This is correct.
  • Option D: Tissues are made up of cells and are at a lower level of organization than organs (and organ systems), so organ systems do not support tissues.

Answer:

D. Cells make up tissues and tissues make up organs.
