7th Grade Science Formative Assessment #4 Multiple Choice Directions: Identify the choice that best completes the statement or answers the question. SC.6.L.14.5 1. In the human body, organ-systems interact with each other to maintain homeostasis. Using the diagram above, explain how this system interacts with another in the body to maintain homeostasis? A. The circulatory and digestive systems interact to produce and deliver oxygen to the body. B. The digestive and excretory systems interact to produce and remove waste from the body. C. The respiratory and digestive systems work together to produce and transport nutrients to all cells in the body. D. The immune and digestive systems work together to provide protection against infectious organisms in the body. SC.6.L.14.5 2. Every cell in our body needs oxygen and nutrients to produce energy. When we inhale, oxygen is taken into and transported to various parts of the body. Cells use oxygen to break down the nutrients we get from the food we eat to release energy. During this process waste products are produced. Which organ systems work together during the process described above? A. B. C. D. The immune, excretory, and nervous systems. The reproductive, nervous, and digestive systems. The respiratory, circulatory, and digestive systems. The musculoskeletal, circulatory, and reproductive systems. School Board of Broward County (Revised 8/2015) Page 1 of 6 SC.6.L.14.5 3. When you sweat a lot the water content of your blood can drop. Your cells have to maintain a certain level of water and salt in order to function properly. Which systems work together to help maintain homeostasis? A. The nervous system sends a message to the musculoskeletal system to reduce physical activity. B. The respiratory system breathes faster sending a message to the nervous system to reduce heat. C. The circulatory system’s lack of water signals the excretory system to reduce the amount of urine produced. D. The nervous system sends a signal to the digestive system to reduce the absorption of water from the digested food. SC.6.L.14.5 4. Passive immunity can occur naturally when maternal antibodies are transferred to the fetus in the placenta. Which statement best justifies the need for this type of immunity? A. The excretory system of the mother transfers antibodies to the nervous system in order to prevent against skeletal disorders. B. The circulatory system of the mother transfers antibodies to the nervous system to reduce the presence of bacteria in the fetus. C. The reproductive system of the mother transfers antibodies to the immune system of the fetus in order to produce a strong musculoskeletal system. D. The reproductive system of the mother transfers antibodies to the immune system of the fetus in order to prevent diseases that may occur shortly after birth. School Board of Broward County (Revised 8/2015) Page 2 of 6 SC.6.L.14.5 5. A developing fetus requires a tremendous amount of nutrients for growth and development, which systems interact to maintain homeostasis in the mother. A. The circulatory system increases its volume of blood in order to ensure that the proper nutrients are available for both mother and baby in the reproductive organs. B. The circulatory system decreases its volume of blood in order to ensure that both mother and fetus receive an equal amount of nutrients. C. The nervous system decreases its signals to the musculoskeletal system so that the mother experiences decreased pain during pregnancy. D. The nervous system increases its signals to the musculoskeletal system so that both mother and fetus develop properly. SC.6.L.14.5 6. The graph below shows how pulse rate changes with exercise. Which of the following best explains how body systems worked together to create the results shown on the graph? A. As the body exercises using the musculoskeletal system, the circulatory system pumps more blood and oxygen throughout the body. B. As the body uses its excretory system to eliminate wastes, the digestive system takes in more nutrients for growth and development. C. As the body exercises using the musculoskeletal system the respiratory system takes in more oxygen from the environment and releases carbon dioxide. D. As the body breaks down food using the digestive system, the nervous system communicates to the musculoskeletal system to exercise the body so as to prevent weight gain. School Board of Broward County (Revised 8/2015) Page 3 of 6 SC.6.L.14.5 7. The human body has various organ-systems that coordinate their functions to maintain the health of the body. In the illustration below, the larger cell on the right represents a white blood cell and the cells on the left are bacteria. Justify how the figure illustrates coordination of the immune and nervous systems. A. The nervous system has responded to the existence of an infection and has alerted the immune system to produce more bacteria cells. B. The immune system has responded to the presence of the bacteria cells and has alerted the nervous system to reduce the presence of white blood cells. C. The immune system has responded to the existence of infection caused by the bacteria, and alerted the nervous system to increase the production of white blood cells. D. The nervous system has responded to the existence of an infection caused by bacteria, and has alerted the immune system to increase the production of white blood cells. SC.6.L.14.6 8. The Ebola virus can often have symptoms similar to bacterial pneumonia, an infection of the lungs. These symptoms include chest pains, shortness of breath and fever. Which statement best summarizes the differences between these two diseases? A. B. C. D. Viruses can replicate because they are living organisms, while bacteria cannot. Viruses can be beneficial to living organisms but bacteria are often infectious. Viruses are not living organisms, but bacteria are living. Viruses are living organisms, while bacteria are not. SC.6.L.14.6 9. Which statement best compares bacteria and fungi? A. B. C. D. Bacteria and fungi always cause infectious diseases. Bacteria are living organisms, whereas, fungi are not. Both bacteria and fungi rely on living organisms to reproduce and survive. Most bacteria and fungi are harmless and may be beneficial to other living things. School Board of Broward County (Revised 8/2015) Page 4 of 6 SC.6.L.14.6 10. Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses? A. Although both rely on other living organisms to survive, viruses are usually beneficial. B. Although both rely on other living organisms to survive, parasites feed on the host organism. C. Although both are living organisms, parasites depend on the cells of living things to reproduce. D. Although both are living organisms, viruses break down dead plants and animals that other organisms use.
