- B.
  
  Very large organisms that we can see with the naked eye using a telescope.
- C.
  
  Very small organisms that we cannot see with the naked eye. In order to see them we need a very powerful microscope.
- D.
  
  Very large organisms that we can see with the naked eye using a microscope.
Correct Answer
C. Very small organisms that we cannot see with the naked eye. In order to see them we need a very powerful microscope.

Explanation
Germs are very small organisms that cannot be seen with the naked eye. To observe them, a powerful microscope is required. This is because germs are microscopic in size, making them invisible to the human eye.

How many types of germs are there?
- A.
  
  1
- B.
  
  2
- C.
  
  3
- D.
  
  4
Correct Answer
C. 3

Explanation
There are three main types of germs: bacteria, viruses, and fungi. Each type of germ has its own characteristics and can cause different types of infections or illnesses. Bacteria are single-celled organisms that can reproduce on their own and can be found almost everywhere. Viruses are much smaller than bacteria and need a host to survive and reproduce. Fungi, such as molds and yeasts, are multi-celled organisms that can cause infections in humans. Therefore, the correct answer is 3.

What kinds of germs are there? Select all that apply.
- A.
  
  Bacteria
- B.
  
  Organisms
- C.
  
  Viruses
- D.
  
  Fungi
Correct Answer(s)
A. Bacteria
C. Viruses
D. Fungi

Explanation
Bacteria, viruses, and fungi are all types of germs. Bacteria are single-celled microorganisms that can cause infections and diseases. Viruses are even smaller than bacteria and are responsible for causing various illnesses. Fungi are a group of organisms that include yeasts, molds, and mushrooms, and they can also cause infections in humans. Therefore, all three options (bacteria, viruses, and fungi) are correct when identifying the different types of germs.

4.

Germs always make us sick.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
This statement is false. While germs can cause illness, not all germs make us sick. Our immune system is capable of fighting off many germs and keeping us healthy. Additionally, some germs are beneficial and necessary for our overall health and well-being.

5.

Our body has special defenses to prevent pathogens from making us sick. These defenses are: (Check all that apply)
- A.
  
  Skin
- B.
  
  Nose
- C.
  
  Leg
- D.
  
  Arm
- E.
  
  Mouth/Throat
- F.
  
  Fighting Cells
Correct Answer(s)
A. Skin
B. Nose
E. Mouth/Throat
F. Fighting Cells

Explanation
The skin acts as a physical barrier to prevent pathogens from entering the body. The nose contains tiny hairs and mucus that trap and filter out pathogens. The mouth and throat have saliva and mucus that contain enzymes and antibodies to kill or neutralize pathogens. Fighting cells, such as white blood cells, are part of the immune system and help to identify and destroy pathogens. Legs and arms are not directly involved in preventing pathogens from making us sick.

How many types of fighting cells are in our blood stream?
- A.
  
  1
- B.
  
  2
- C.
  
  3
- D.
  
  4
Correct Answer
B. 2

Explanation
There are two types of fighting cells in our blood stream. These are white blood cells, also known as leukocytes, and platelets. White blood cells play a crucial role in our immune system by defending our body against infections and diseases. Platelets, on the other hand, are responsible for blood clotting and preventing excessive bleeding. Therefore, the correct answer is 2.

White blood cells and antibodies are fighting cells that attack those pathogens that pass through our skin, nose, or throat, and mouth and gets into our blood stream.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
White blood cells and antibodies are part of our immune system and play a crucial role in defending our body against pathogens. When pathogens enter our body through the skin, nose, throat, or mouth, white blood cells and antibodies recognize them as foreign invaders and launch an immune response to eliminate them. They work together to identify, neutralize, and destroy pathogens in our bloodstream, preventing them from causing harm and infection. Therefore, the statement that white blood cells and antibodies attack pathogens that enter our bloodstream is true.
