Question

_______ are at a higher taxonomic level of organization than _______.

Which of the following completes the sentence above?

1. organ, organ system
2. cells, molecules
3. atoms, molecules
4. tissues, organs

Answer 1

The correct answer fills the blank with 'organisms' and 'organs,' illustrating that at a higher level of biological organization, an organism comprises multiple organ systems, each made from individual organs.

Step-by-step explanation:

The correct completion of the sentence is: Organisms are at a higher taxonomic level of organization than organs. This is because in the hierarchy of biological organization, an organism is composed of various organ systems, and each organ system is composed of individual organs. At each increasing level of organization, the complexity and coordination of structures and functions increase, leading to higher levels of biological organization.

Life processes of the human body are maintained at several levels of structural organization, such as chemical, cellular, tissue, organ, organ system, and organism levels. Atoms come together to form molecules, molecules come together to form cells, cells come together to form tissues, tissues come together to form organs, and organs come together to form organ systems, which collectively make up an organism.
