Biology Regents Questions

Although the digestive system is primarily  responsible for the breakdown of food, this  process can be disrupted if the circulatory  system malfunctions. The best explanation for  this disruption is that...  

•   (1) the circulatory system is the control center of the body
•   (2) human body systems interact with each other to perform life functions
• (3) the digestive system and the circulatory  system have many organs in common  
• (4) the circulatory system is responsible for the  coordination of life functions, including the  breakdown of food

Which body system is correctly paired with its function?

•   (1) excretory—produces antibodies to fight disease-causing organisms
•   (2) digestive—produces hormones for storage
• (3) circulatory—transports materials for energy release in body cells
•   (4) respiratory—collects waste material for digestion

The list below includes three organs systems that are directly used when a human runs.
Circulatory
Muscular
Skeletal
Which system should also be included?

• (1) Immune system
• (2) Reproductive system
• (3) Digestive system
• (4) Nervous system

When people exercise, their body cell build up more waste quickly. Which two body systems work together to remove these wastes from cells of the body?

• (1) Circulatory and Excretory
• (2) Respiratory and Digestive
• (3) Digestive and Circulatory
• (4) Circulatory and Respiratory

The cytoplasm in a single celled organism and a the circulatory system in a human both...

• (1) Break down molecules into smaller components
• (2) Release energy to be used by the organism
• (3) Transport substances throughout the organism
• (4) Distribute blood to all of the parts of the organism

 
 
 
 
 
 
 
 
 
 In the diagram above, which letter indicates the part of the cell that carries out a function most similar to a function of the human excretory system?

• (1) A
• (2) B
• (3) C
• (4) D

The interaction of which two systems provides the molecules needed for the metabolic activity that takes place at ribosomes?

• (1) digestive and circulatory   
• (2) reproductive and excretory
•    (3) immune and nervous
•    (4) respiratory and muscular

The respiratory system includes a layer of cells in the air passages that clean the air before it gets   to the lungs. This layer of cells is best classified as...

• (1) an organ system             
•   (2) an organ               
• (3) an organelle
• (4) a tissue

  Which statement describing the cells in a body system is correct?  

•  (1) Each cell in the system is identical to the other cells in the system, and each cell works independently of the other cells. 
•  (2) Some cells in the system may be different from the other cells in the system, but all cells are coordinated and work together. 
•  (3) Each cell in the system is different from the other cells in the system, and each cell works independently of the other cells. 
•  (4) All cells in the system are identical to each other and work together.

lf a human system fails to function properly, what is the most likely result? 

•  (1) a stable rate of metabolism 
•  (2) a disturbance in homeostasis 
•  (3) a change in the method of cellular respiration 
•  (4) a change in the function of DNA
