Question

Chapter 11, Problem 1Q

Summary Introduction

(a)

To Determine:

If the given statement is true or false should be determined.

Introduction:

Primary immune response refers to the series of immunological events that are triggered by the first exposure to a pathogen.

The secondary immune response is referred to as the quick fight-back of the immune system to a previously exposed pathogen from the memory it holds from the first exposure.

Expert Solution

Answer to Problem 1Q

The given statement is false.

Explanation of Solution

Option (a) is given as secondary immune responses take the same amount of time as primary immune responses to become effective. Secondary immune responses are faster and stronger than primary ones due to the memory it holds of the previous encounter of the infection. Hence, this option is false.

Summary Introduction

(b)

To Determine:

If the given statement is true or false should be determined.

Introduction:

Primary immune response refers to the series of immunological events that are triggered by the first exposure to a pathogen.

The secondary immune response is referred to as the quick fight-back of the immune system to a previously exposed pathogen from the memory it holds from the first exposure.

Expert Solution

Answer to Problem 1Q

The statement is true.

Explanation of Solution

Option (b) is given as on the secondary exposure to an infectious agent there is reduced mortality. The secondary exposure to the infectious agent is combatted by the secondary immune response which is stronger and more effective than the first encounter event. Hence mortality is reduced. So, this option is true.

Summary Introduction

(c)

To Determine:

If the given statement is true or false should be determined.

Introduction:

Primary immune response refers to the series of immunological events that are triggered by the first exposure to a pathogen.

The secondary immune response is referred to as the quick fight-back of the immune system to a previously exposed pathogen from the memory it holds from the first exposure.

Expert Solution

Answer to Problem 1Q

The statement is false.

Explanation of Solution

Option (c) is given as only immune responses made in mucosal secondary lymphoid tissues can provide protective immunity. Antibodies are produced by both bone marrow cells and lymphoid tissues underneath the mucosal surfaces that bring about the protective immunity. Hence this option is false.

Summary Introduction

(d)

To Determine:

If the given statement is true or false should be determined.

Introduction:

Primary immune response refers to the series of immunological events that are triggered by the first exposure to a pathogen.

The secondary immune response is referred to as the quick fight-back of the immune system to a previously exposed pathogen from the memory it holds from the first exposure.

Expert Solution

Answer to Problem 1Q

The statement is true.

Explanation of Solution

Option (d) is given as if an individual acquires a second cold in the same seaSo,n it will be most probably caused by a different type of cold virus. Since there exists memory against pathogens once attacking the immune system, there is negligible chance that in one seaSo,n a perSo,n can be affected twice by the same bug. Secondary immune response eliminates this possibility. Hence this option is true.

Summary Introduction

(e)

To Determine:

If the given statement is true or false should be determined.

Introduction:

Primary immune response refers to the series of immunological events that are triggered by the first exposure to a pathogen.

The secondary immune response is referred to as the quick fight-back of the immune system to a previously exposed pathogen from the memory it holds from the first exposure.

Expert Solution

Answer to Problem 1Q

The statement is true.

Explanation of Solution

Option (e) is given as plasma cells generated in the secondary immune response have longer life spans than those made during the primary immune response. Plasma cells generated in the primary immune response have a shorter life as they are rapidly killed by apoptosis or lack of contact with stromal cells which causes inhibitory survival responses in them. Hence this option is true.

Summary Introduction

(f)

To Determine:

If the given statement is true or false should be determined.

Introduction:

Primary immune response refers to the series of immunological events that are triggered by the first exposure to a pathogen.

The secondary immune response is referred to as the quick fight-back of the immune system to a previously exposed pathogen from the memory it holds from the first exposure.

Expert Solution

Answer to Problem 1Q

The statement is false.

Explanation of Solution

Option (f) is given as during primary immune response, only memory B-cells are generated. During primary immune response both effector and memory B cells are generated along with effector and memory T-cells. Hence this option is false.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
