Answer:
The five levels of organization are:
- Cells
- Tissues
- Organs
- Organ Systems
- Organism
Explanation:
Five Levels of Organization:
Cells:
Cells are the fundamental levels of organization of living organisms. They are the basic structural and functional units of life. Cells are composed of different organelles that perform various functions and through division of labor, accomplish different cellular tasks. E.g, muscle cell, neuron (nervous system cells), nephron (specialized kidney cells) etc.
Tissues:
Cells that perform similar functions combine together to form tissues. For example, skeletal muscle tissue, cardiac muscle, vascular tissue etc.
Organs:
Organs are complex structures formed by the combination pf two or more types of tissues that perform specific but related functions. E.g, heart (pumps blood, contains cardiac muscle tissue), brain (conducts nerve impulses, contains neural tissue).
Organ Systems:
Organ systems are a combination of organs that perform related functions and work together to perform specific physiological functions. E.g, circulatory system (contains heart and circulatory system).
Organism:
This is the highest level of organization. An organism is a combination of cells, tissues, organs and organ systems that all work together to perform specific physiological functions.
Answer:
A. Archaea have DNA that is not in a nucleus.
Explanation:
Eukaryotes are the organisms that have well defined membrane bound nucleus and other membrane bound organelles in their cells. The domain eukarya include both unicellular and multicellular organisms. Archaea include the unicellular prokaryotic organisms that lack the membrane bound nucleus and membrane bound organelles.

No, he is not correct. Xenon is not very reactive since it is located in the group of noble gases.
