Science Final Review

Which two systems of the human body interact to maintain homeostasis by utilizing white blood cells against invaders?

• immune and circulatory

• cardiovascular and integumentary

• endocrine and immune

• respiratory and cardiovascular

Which of the following systems of the body interact when a stressful situation causes a person's heart rate to increase and pupils of the eyes to dilate?

• nervous system and digestive system

• nervous system and excretory system

• respiratory system and nervous system

• circulatory system and nervous system

Which of the following best explains how the systems in the human body work together to maintain homeostasis and remove excess carbon dioxide?

• The circulatory system takes in less carbon dioxide, and the lungs transport more oxygen to and from the tissues.

• The circulatory system takes in more oxygen, and the skin transports the oxygen and carbon dioxide to and from the tissues.

• The respiratory system takes in more oxygen, and the blood transports the oxygen and carbon dioxide to and from the tissues

• The respiratory system takes in less carbon dioxide, and the heart pumps more oxygen to and from the tissues.

Which statement provides the BEST evidence that the circulatory system interacts with the immune system to carry out life processes?

• The circulatory system works with the immune system by processing toxins in the liver.

• The circulatory system provides transport for the immune cells that enable the immune system to fight infections.

• The circulatory system works with the immune system to act like a barrier to prevent bacteria from entering the body.

• The circulatory system works with the immune system to act like a barrier to prevent bacteria from entering the body.

Other systems interact with the digestive system to maintain homeostasis. One system moves food through the digestive system so that it can be broken down into nutrients through mechanical digestion. Another system then delivers those nutrients from the digestive system to the rest of the body. Select the two systems which are responsible for these interactions.

• Nervous

• Immune

• Muscular

• Respiratory

• Cardiovascular

Which sequence lists structures in order from the least complex to the most complex?

• chloroplast, plant cell, leaf, rosebush

• rosebush, leaf, plant cell, chloroplast

• plant cell, leaf, chloroplast, rosebush

• chloroplast, leaf, plant cell, rosebush

Atoms → Molecules → Cells → ? → Organs → Organ Systems → Organism

Which level of organization is missing from the arrow diagram?

• blood

• bones

• tissue

• muscles

What is the highest level of organization of the starfish?

• The cell

• Organ system

• Organs

• Organism

A science teacher shows students a “working” model of a plant cell. The model transforms the same kind of energy as a plant cell, but it stores the energy in a battery. The teacher places the plant cell model on the windowsill. Which prediction about its behavior is accurate?

• The model will release oxygen at the same time that it charges its battery.

• The model will consume carbon dioxide at the same time that it charges its battery.

• The model will charge its battery during the high temperatures of summer months.

• The model will charge its battery during daylight hours only.
