  • 2. 

    Cells, tissue, and organs work together to form a/an

    • Cells

    • Tissue

    • Organ

    • Organ System

    Correct Answer
    A. Organ System
    Explanation
    Cells, tissues, and organs are all components of living organisms. Cells are the basic building blocks of life, while tissues are groups of cells that work together to perform a specific function. Organs, on the other hand, are composed of different types of tissues and have specialized functions. An organ system is a group of organs that work together to perform a specific function for the organism as a whole. Therefore, the correct answer is organ system, as it encompasses the collaboration of cells, tissues, and organs to carry out specific physiological processes.

    The brain, kidneys and lungs are all examples of:

    • Cells

    • Tissue

    • Organs

    • Organ System

    Correct Answer
    A. Organs
    Explanation
    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 specific role and is made up of multiple tissues that are specialized for that function. The brain is responsible for controlling and coordinating various bodily activities, the kidneys filter waste products from the blood, and the lungs facilitate the exchange of oxygen and carbon dioxide. Therefore, organs are the correct answer as they are the higher level of organization in the body compared to cells and tissues.

    Rate this question:

  • 4. 

    A group of organs working together to perform a specific function is know as a/an:

    • Cell

    • Tissue

    • Organ

    • Organ System

    Correct Answer
    A. Organ System
    Explanation
    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 to play, and together they collaborate to carry out complex tasks necessary for the body's overall functioning. This level of organization allows for specialization and efficiency in performing specific functions, such as digestion, circulation, or respiration.

    Rate this question:

  • 5. 

    Cells are what level of organization

    Correct Answer
    1st
  • 6. 

    Cells that are similar in structure and function join together to form

    • Cells

    • Tissue

    • Organ

    • Organ Systen

    Correct Answer
    A. Tissue
    Explanation
    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 classified into four main types: epithelial, connective, muscle, and nervous tissue. Each type of tissue has its own unique structure and function, allowing them to carry out specific tasks in the body.

  • 7. 

    Cells that are ______________________ in structure and fuction join together to form tissues.

    Correct Answer
    similar
    Explanation
    Cells that are similar in structure and function join together to form tissues. This means that cells with similar characteristics and roles come together to create specialized groups that perform specific functions in the body. These cells share common features and work together to carry out specific tasks, such as muscle contraction or nerve transmission. By joining together, they create tissues that have a unified purpose and contribute to the overall functioning of the organism.

  • 8. 

    Digestive system, respiratory system and integumentary system are examples of:

    Correct Answer
    organ systems
    Explanation
    The digestive system, respiratory system, and integumentary system are all examples of organ systems. Organ systems are groups of organs that work together to perform specific functions in the body. The digestive system is responsible for breaking down food and absorbing nutrients, the respiratory system is responsible for exchanging oxygen and carbon dioxide, and the integumentary system is responsible for protecting the body and regulating temperature. These systems rely on the coordination and interaction of multiple organs to carry out their functions.

    Within a multicellular organism there is a _________________ _________ _____________ among the different parts of the  body.

    Correct Answer
    division of labor
    Explanation
    Within a multicellular organism, there is a division of labor among the different parts of the body. This means that each part of the organism has a specific role or function to perform in order to maintain the overall functioning and survival of the organism as a whole. This division of labor allows for specialization and efficiency, as different cells and tissues can focus on specific tasks such as digestion, respiration, movement, or reproduction, ensuring the proper functioning and coordination of the entire organism.

    Rate this question:

  • 10. 

    Tissues are the __________ (number) level of organization.

    Correct Answer
    2nd
    Explanation
    Tissues are the second level of organization in the body. This refers to the grouping of similar cells that work together to perform a specific function. At this level, cells join together to form tissues such as muscle, nerve, or connective tissue. The organization of tissues is a crucial step in building more complex structures in the body.
