which sequence of biological structures within the human body is organized from simplest to most complex?
A. bone cells, bone tissue, bone, skeletal system
B. bone tissue, bone cells, bone, skeletal system
C. skeletal system, bone, bone cells, bone tissue
D. skeletal system, bone, bone tissue, bone cells
bone cells, bone tissue, bone, skeletal system
The correct answer is D. skeletal system, bone, bone tissue, bone cells.
To determine which sequence of biological structures within the human body is organized from simplest to most complex, we need to understand the hierarchy of organization in the human body.
The human body is organized in a hierarchical manner, from the simplest level to the most complex level. This hierarchy is as follows:
1. Cells: Cells are the building blocks of all living organisms and are the simplest level of organization in the human body. Cells perform specific functions and come together to form tissues.
2. Tissues: Tissues are groups of cells with similar structures and functions that work together to perform a specific task. There are four main types of tissues in the human body: epithelial, connective, muscle, and nervous tissues.
3. Organs: Organs are composed of different types of tissues that work together to perform a specific function. Examples of organs in the human body include the heart, lungs, liver, and kidneys.
4. Systems: Systems are groups of organs that work together to perform specific functions in the body. Examples of systems in the human body include the skeletal system, muscular system, cardiovascular system, and respiratory system.
Now, let's analyze the sequence options:
A. bone cells, bone tissue, bone, skeletal system: This sequence starts with bone cells, which are cells (the simplest level of organization). It then progresses to bone tissue, which is a type of tissue (a higher level of organization). Next is bone, which is an organ (an even higher level of organization). Finally, it ends with the skeletal system, which is a system (the highest level of organization). This option is organized from simplest to most complex.
B. bone tissue, bone cells, bone, skeletal system: This sequence starts with bone tissue, which is a type of tissue. It then progresses to bone cells, which are cells. Next is bone, which is an organ. Finally, it ends with the skeletal system, which is a system. This option is also organized from simplest to most complex.
C. skeletal system, bone, bone cells, bone tissue: This sequence starts with the skeletal system, which is a system (the highest level of organization). It then progresses to bone, which is an organ. Next are bone cells, which are cells (a lower level of organization). Finally, it ends with bone tissue, which is a type of tissue (the lowest level of organization). This option is organized from most complex to simplest.
D. skeletal system, bone, bone tissue, bone cells: This sequence starts with the skeletal system, which is a system. It then progresses to bone, which is an organ. Next is bone tissue, which is a type of tissue. Finally, it ends with bone cells, which are cells. This option is also organized from most complex to simplest.
Based on the hierarchy of organization in the human body, the correct sequence, organized from simplest to most complex, is:
A. bone cells, bone tissue, bone, skeletal system.
