  • 2. 

    The basic unit of structure and function in all living things:

    • Cells

    • Tissue

    • Organ

    • Organ System

    Correct Answer
    A. Cells
    Explanation
    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.

    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 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:

  • 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, 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.

  • 5. 

    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 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:

  • 6. 

    Cells are what level of organization

    Correct Answer
    1st , first, 1, 3, third, 3rd
    Explanation
    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:

  • 7. 

    Tissues are the __________ (number) level of organization.

    Correct Answer
    2nd, 2, two, second
    Explanation
    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. 

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

    Correct Answer
    organ systems, organ system
    Explanation
    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:

  • 9. 

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

    Correct Answer
    similar, the same
    Explanation
    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:

  • 10. 

    In the levels of organization in an organism, a group of similar cells working together is called a __________.

    Correct Answer
    tissue, Tissue
    Explanation
    In biology, the levels of organization are structured hierarchically, starting from the simplest building blocks to the most complex living entities. A tissue is a group of similar cells that perform a specific function. For example, muscle tissue is composed of muscle cells that contract to produce movement, while nervous tissue is made up of neurons that transmit signals throughout the body. Tissues then combine to form organs, which further group into organ systems, ultimately creating a complete organism.
