Question

Which of the following sequences of terms moves nicely from less complex to more complex?

a. organs -individuals - organ systems - populations
b. cells - organelles - tissues - organs
c. macro-molecular complexes - biomolecules - cells - organelles
d. atoms -- cells - organs - organelles
e. atoms - biomolecules - macro-molecular complexes - organelles

Answer 1

E is correct

Step-by-step explanation:

We can check them 1 by 1.

a lists individuals as less complex than organ systems. Assuming individuals means individual organisms, individuals are made of organ systems, so they are more complex so it's incorrect.

b lists cells as less complex than organelles, so it's incorrect. Cells are made of organelles, so they are more complex.

c has the same error as b, listing organelles as more complex than cells.

d lists organelles above organs and cells, so it's incorrect.

Logically it would only leave e, but we can check. Atoms make biomolecules, or molecules with carbon, Those make monomers, which further make macromolecules. Skipping a lot of steps, the organelles are the most complex of all of these. So e is the answer.

Answer 2

The correct sequence that moves nicely from less complex to more complex is cells - organelles - tissues - organs. This sequence follows the hierarchical organization of living things, starting from the smallest unit of life (cells) and progressing to larger structures (organelles, tissues, and organs) that are composed of cells.

Step-by-step explanation:

The correct sequence that moves nicely from less complex to more complex is b. cells - organelles - tissues - organs. This sequence follows the hierarchical organization of living things, starting from the smallest unit of life (cells) and progressing to larger structures (organelles, tissues, and organs) that are composed of cells. Here is a step-by-step breakdown of the sequence:

1. Cells: Cells are the basic structural and functional units of living organisms. They are capable of carrying out essential life processes.
2. Organelles: Organelles are specialized structures within cells that perform specific functions. Examples of organelles include the nucleus, mitochondria, and chloroplasts.
3. Tissues: Tissues are groups of similar cells that work together to perform a specific function. Examples of tissues include muscle tissue, nervous tissue, and epithelial tissue.
4. Organs: Organs are composed of different tissues working together to carry out a particular function. Examples of organs include the heart, liver, and lungs.

This sequence demonstrates the increasing complexity and organization of living things as you move from cells to organelles to tissues and finally to organs.
