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. The immune, excretory, and nervous systems.
B. The reproductive, nervous, and digestive systems.
C. The respiratory, circulatory, and digestive systems.
D. The musculoskeletal, circulatory, and reproductive systems.
C The respiratory, circulatory, and digestive systems.
Which statement best compares bacteria and fungi? A. Bacteria and fungi always cause infectious diseases.
B. Bacteria are living organisms, whereas, fungi are not.
C. Both bacteria and fungi rely on living organisms to reproduce and survive.
D. Most bacteria and fungi are harmless and may be beneficial to other living things.
D. Most bacteria and fungi are harmless and may be beneficial to other living things.
Fungi are ____________ because they must obtain their nutrients from other organic matter. However viruses do not need to feed but need a host to reproduce and are similar to ___________
a. heterotrophs
b. parasites.
Define Homeostasis
Process of a living organism goes through to maintain internal balance
Organisms are made ______________
Organ systems
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’s nervous system is stimulated by exercise, the body’s circulatory system is less able to regulate body temperature.
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.
A. As the body exercises using the musculoskeletal system, the circulatory system pumps more blood and oxygen throughout the body.
