A group of organs working together to perform a specific function is know as a/an:
- A.
Cell
- B.
Tissue
- C.
Organ
- D.
Organ System
Correct Answer
D. Organ SystemExplanation
An organ system is a group of organs that work together to perform a specific function. Each organ within the system has a specific role, and they collaborate to carry out a particular task or process in the body. For example, the respiratory system includes organs such as the lungs, trachea, and bronchi, which work together to facilitate the exchange of gases. Therefore, an organ system best describes a group of organs working together to perform a specific function.Rate this question:

Cells that are similar in structure and function join together to form
- A.
Cells
- B.
Tissue
- C.
Organ
- D.
Organ Systen
Correct Answer
B. TissueExplanation
Cells that are similar in structure and function join together to form tissue. Tissues are groups of cells that work together to perform a specific function in the body. They can be categorized into four main types: epithelial, connective, muscle, and nervous tissue. Epithelial tissue covers and protects body surfaces, connective tissue provides support and structure, muscle tissue allows for movement, and nervous tissue transmits and processes information. By joining together, cells form tissues that enable specialized functions and contribute to the overall functioning of organs and organ systems.Rate this question:

Cells, tissue, and organs work together to form a/an
- A.
Cells
- B.
Tissue
- C.
Organ
- D.
Organ System
Correct Answer
D. Organ SystemExplanation
Cells, tissues, and organs work together to form an organ system. An organ system is a group of organs that work together to perform a specific function in the body. Each organ within the system has a specific role, and they collaborate to maintain homeostasis and carry out vital processes. Examples of organ systems include the respiratory system, circulatory system, and digestive system. Therefore, the correct answer is Organ System.Rate this question:

The basic unit of structure and function in all living things:
- A.
Cells
- B.
Tissue
- C.
Organ
- D.
Organ System
Correct Answer
A. CellsExplanation
Cells are the basic unit of structure and function in all living things. They are the smallest building blocks of life and are responsible for carrying out all the essential processes necessary for an organism's survival. Cells can exist as single-celled organisms or work together to form tissues, organs, and organ systems. They are responsible for carrying out functions such as reproduction, metabolism, and response to stimuli. Without cells, living organisms would not be able to carry out the complex processes required for life.Rate this question:

The brain, kidneys and lungs are all examples of:
- A.
Cells
- B.
Tissue
- C.
Organs
- D.
Organ System
Correct Answer
C. OrgansExplanation
The brain, kidneys, and lungs are all examples of organs. Organs are composed of different types of tissues that work together to perform specific functions in the body. Each organ has a unique structure and function, and they are part of larger organ systems that work together to maintain homeostasis and carry out essential bodily functions.Rate this question:

Cells that are ______________________ in structure and fuction join together to form tissues.
Correct Answer
similar, the sameExplanation
Cells that are similar in structure and function join together to form tissues. This means that the cells have comparable characteristics and perform similar tasks. When cells with similar properties come together, they can collaborate and work in harmony to carry out specific functions within the body. This organization at the cellular level allows for the efficient functioning of tissues and ultimately contributes to the overall functioning of organs and systems in the body.Rate this question:
- 7.
Tissues are the __________ (number) level of organization.
Correct Answer
2nd, 2, two, secondExplanation
Tissues are the second level of organization in living organisms. This means that after cells, tissues are formed by a group of similar cells working together to perform a specific function. This organization allows for more complex structures and functions to develop in multicellular organisms.Rate this question:
- 8.
Within a multicellular organism there is a _________________ _________ _____________ among the different parts of the body.
Correct Answer
division of laborExplanation
In a multicellular organism, there is a division of labor among the different parts of the body. This means that each cell or group of cells has a specific role or function to perform in order to ensure the proper functioning of the organism as a whole. This division of labor allows for specialization and efficiency, as different cells can focus on specific tasks such as digestion, respiration, or reproduction. By dividing the workload among different parts, the organism can function more effectively and efficiently.Rate this question:
- 9.
Cells are what level of organization
Correct Answer
1st , first, 1, 3, third, 3rdExplanation
The given correct answer is "1st, first, 1, 3, third, 3rd". This answer suggests that cells are the first level of organization. This is because cells are the basic structural and functional units of all living organisms. They are the building blocks of tissues, organs, and ultimately, entire organisms. Therefore, cells can be considered as the foundational level of organization in biological systems.Rate this question:

Digestive system, respiratory system and integumentary system are examples of:
Correct Answer
organ systems, organ systemExplanation
The digestive system, respiratory system, and integumentary system are examples of organ systems. An organ system is a group of organs that work together to perform a specific function in the body. Each system has its own set of organs that contribute to the overall function of the system. Therefore, the correct answer is organ systems, referring to the multiple systems in the body, and organ system, referring to each individual system.Rate this question:
