(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.

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.
(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.

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.
(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.

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.
(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.

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.
(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.

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.
(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.

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.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
