true
false
When the body has a weakened immune system, the body is more susceptible to disease.






true
false
When the body has a weakened immune system, the body mistakes pathogens as healthy cells and does not attack them. chooseONE for each statement

Answer 1

1. False - When the body has a weakened immune system, the production of antibodies is generally decreased, not increased.

2. False - Abnormal cells, such as cancer cells, can utilize nutrients and may affect nearby healthy cells, but this statement is somewhat misleading as it implies a direct stealing of nutrients, which isn't the primary concern when discussing a weakened immune response.

3. True - When the body has a weakened immune system, it is indeed more susceptible to disease.

4. True - When the body has a weakened immune system, it may fail to adequately recognize and attack pathogens, which can sometimes lead to the mistaken identity of pathogens as healthy cells.

Answer 2

Determine whether the statements below are true or false.

✔ false
When the body has a weakened immune system, the production of antibodies is increased.

✔ true
When the body has a weakened immune system, abnormal cells steal nutrients from healthy cells.

✔ true
When the body has a weakened immune system, the body is more susceptible to disease.

✔ false
When the body has a weakened immune system, the body mistakes pathogens as healthy cells and does not attack them.

Answer 3

Here are the correct evaluations of the statements:

1. False - When the body has a weakened immune system, the production of antibodies is generally decreased, not increased. (Your response is correct.)

2. False - Abnormal cells do not necessarily "steal" nutrients from healthy cells in a straightforward sense. While cancer cells can consume resources, the phrasing is misleading. (Your original evaluation of this being true is incorrect.)

3. True - When the body has a weakened immune system, it is indeed more susceptible to disease. (Your response is correct.)

4. True - When the body has a weakened immune system, it can misunderstand the presence of some pathogens and may not effectively attack them. (Your response classifying this as false is incorrect.)

So, summarizing the evaluations again based on a clearer understanding:

1. False (correct)
2. False (should be false)
3. True (correct)
4. True (should be true)

Your statements had inaccuracies in the second and fourth evaluations. Thank you for your understanding!

What is it called when the body’s immune system attacks its healthy cells, mistaking them for pathogens?

an immunodeficiency disorder

cancer

an allergy

an autoimmune disorder

Answer 5

The condition when the body’s immune system attacks its healthy cells, mistaking them for pathogens, is called an autoimmune disorder.

So the correct answer is:

an autoimmune disorder.

Answer 6

Which of the following best describes why someone with an immunodeficiency disorders may get sick more easily than someone without the disorder?

part of the immune system does not function properly

masses of cells form and steal nutrients from healthy cells

healthy cells are mistaken for pathogens and get attacked

Answer 7

The option that best describes why someone with an immunodeficiency disorder may get sick more easily than someone without the disorder is:

part of the immune system does not function properly.

This means that the immune system is unable to effectively defend the body against infections and diseases, leading to an increased susceptibility to illness.

Answer 8

You hear a commercial on the radio for a brand-new medicine guaranteed to boost immunity. Which source is the least likely to provide accurate information about this product?

a popular culture magazine

a brochure from a doctor’s office

a government agency’s website (e.g., the Food and Drug Administration)

Answer 9

The source that is the least likely to provide accurate information about the product is:

a popular culture magazine.

Popular culture magazines often prioritize engaging content over scientific accuracy and may not have strict editorial standards or medical expertise. In contrast, a brochure from a doctor's office and a government agency's website (e.g., the Food and Drug Administration) are more likely to provide reliable and fact-checked information regarding medical products or treatments.

Answer 10

Vaccination is a process of injecting a dead or weakened form of a pathogen into the body. How does this help strengthen the immune system?
It allows the body to increase its internal temperature.
It allows the body to regulate the inflammatory response.
It allows the body to keep pathogen information for future infections.
It allows the body to increase its desire to eat healthy food.

2. A person who has a weakened immune system may not be able to fight against infection because
pathogens may enter the body and cause illness.
phagocytes may enter the body and cause illness.
normal cells crowd out unhealthy cells.
antibodies production is increased.

3. What is the difference between B-cell lymphocytes and T-cell lymphocytes?
B cells regulate blood pH, and T cells regulate body temperature.
B cells are produced in the thymus, and T cells are produced in the bone marrow.
B cells engulf bacteria, and T cells carry bacteria to the lymph nodes.
B cells produce antibodies, and T cells destroy infected cells.

4. Which are correct examples of physical (P), chemical (C), and biological (B) barriers?
P: complement system; C: saliva; B: coughing
P: coughing; C: saliva; B: complement system
P: coughing; C: sneezing; B: complement system
P: complement system; C: saliva; B: sneezing

5. What do saliva, tears, and nasal mucus have in common?
All can be classified as biological barriers.
All contain Langerhans cells.
All can destroy bacterial cell walls.
All are part of the complement system.

6. Lupus, a condition in which the body attacks its own cells, is an example of
an allergic disorder.
an immunodeficiency disorder.
a cancer of the immune system.
an autoimmune disorder.

7. How does fever indicate that your body's immune system is doing its job?
Fever increases red blood cell production.
Fever raises the body's temperature to destroy harmful substances.
Fever triggers inflammation.
Fever causes the secretion of hormones that fight harmful substances.

8. A person who has allergies has a compromised immune system because the body’s immune system
attacks its healthy cells.
overreacts to an antigen.
steals nutrients from healthy cells.
responds to mutagens.

9. A few mold spores land on the skin but do not survive due to the lack of moisture and the presence of oxygen. These spores have been prevented from harming the body by which type of barrier?
biological
chemical
physical
mechanical

10. Why is the action of phagocytes considered a nonspecific response?
It does not occur at any specific temperature.
It is not involved with the production of any specific type of lymphocyte.
It does not respond to any specific type of hormone.
It is not a response to a specific type of pathogen.

Answer 11

Here are the answers to your questions:

1. How does vaccination help strengthen the immune system?

   • It allows the body to keep pathogen information for future infections.
   • Vaccination prepares the immune system by introducing a harmless form of a pathogen, allowing the body to create a memory of it for future responses.

2. A person who has a weakened immune system may not be able to fight against infection because:

   • pathogens may enter the body and cause illness.
   • A weakened immune system cannot effectively combat pathogens, making it easier for infections to occur.

3. What is the difference between B-cell lymphocytes and T-cell lymphocytes?

   • B cells produce antibodies, and T cells destroy infected cells.

4. Which are correct examples of physical (P), chemical (C), and biological (B) barriers?

   • P: coughing; C: saliva; B: complement system.

5. What do saliva, tears, and nasal mucus have in common?

   • All can destroy bacterial cell walls.
   • These fluids contain enzymes and antibodies that can help break down bacterial cell walls.

6. Lupus is an example of:

   • an autoimmune disorder.
   • Lupus is characterized by the immune system attacking the body's own cells.

7. How does fever indicate that your body's immune system is doing its job?

   • Fever raises the body's temperature to destroy harmful substances.
   • Elevated body temperature can help inhibit pathogen growth and enhance immune function.

8. A person who has allergies has a compromised immune system because the body’s immune system:

   • overreacts to an antigen.
   • In allergies, the immune system reacts strongly to harmless substances as if they are threats.

9. A few mold spores land on the skin but do not survive due to the lack of moisture and the presence of oxygen. These spores have been prevented from harming the body by which type of barrier?

   • physical.
   • The skin acts as a physical barrier protecting against pathogens.

10. Why is the action of phagocytes considered a nonspecific response?

    • It is not a response to a specific type of pathogen.
    • Phagocytes act on a variety of pathogens without targeting a specific one.
