Multiple Choice

Which of the following image answer choices below corresponds to a non-specific defense response?

Multiple Choice

Which of the following is an example of specific immunity?

• skin

• fever

• stomach acid

• antibody response

Multiple Choice

Which of the following statements best reflects the role of the nonspecific immune system?

• It is designed as a first line of defense against pathogens.

• It is designed to dispose of pathogens after they have been found.

• It is designed to attack pathogens not found by the specific immune system.

• It is designed to deal only with pathogens that are not a serious threat to the body.

Multiple Choice

Which of the following would best explain the observed immune responses?

• The primary response for the antigen was greater than the secondary response because antibodies were fighting the antigen.

• The primary response for the antigen was greater than the secondary because a vaccine was given to fight the antigen.

• The secondary response for the antigen was greater than the primary response because memory cells were present specifically for the antigen.

• The secondary response for the antigen was greater than the primary response because there were not enough memory cells.

Multiple Choice

Multiple Choice

Crystal is experiencing symptoms of the flu, which is caused by a viral infection. Crystal's friend Mike suggests that she takes some leftover antibiotics from a prior bacterial infection. Is this a valid suggestion?

• Yes because it is generally safe to take antibiotics.

Multiple Choice

Lyme disease is a bacterial illness that is transmitted by ticks and is the most common tickborne

disease in the United States. The cases of Lyme disease have increased as climate change has affected original tick habitats.

What prediction can be made about how

changes in the environment may impact public health?

• Diseases spread by animals will be less common as habitats change and are destroyed.

• More people may become exposed to diseases that were previously contained in specific

  areas.

• Hospitals will be under less strain than normal as changes in climate begin to weaken the

  impacts of disease.

• Changes in the environment will have no impact on human health but will have increased

  impact on ecosystems.

Multiple Choice

The graph compares the normal population to people with the Lynch mutation and their

likelihood of getting cancer.

What is the impact of the Lynch mutation on an individual’s health?

A

• The Lynch mutation has the largest risk difference on an individual’s likelihood to be

  diagnosed with ovarian cancer when compared to the general population.

• The Lynch mutation has the largest risk difference on an individual's likelihood to be

  diagnosed with colorectal cancer when compared to the general population.

• The Lynch mutation has the smallest risk difference on an individual's likelihood to be

  diagnosed with cancer a second time within 15 years of the initial diagnosis.

• The Lynch mutation has the smallest risk difference on an individual’s likelihood to be

  diagnosed with endometrial cancer when compared to the general population.
