n acquired immunity, lymphocyte provides a specific defense against pathogens. The body detects the foreign object or pathogen by certain molecules attached on the outside of invading pathogens or by other foreign objects.Select one:a.TRUEb.FALS

Defense of the body against a specific pathogen is provided byQuestion 1Select one:a.innate immunity. b.adaptive immunity. c.immunological surveillanced.skin defenses. e.fever.

Antigens:Question 22Select one or more:a. are used by the immune system to identify what is part of the body and what is a pathogen.b.are often large proteins (some carbohydrates and lipids can also be antigenic).c.stimulate the activity of T and B lymphocytes.d.are found on the surface of cells (both pathogens and body cells), and on pollen, toxins, and food.

The adaptive immune system responds to foreign molecules, typically protein components of bacteria, viruses, molds, or parasites, which are collectively known as .

Acquired immunitya involves the production of secretions of the skin and mucous membranes inresponse to pathogensb involves nonspecific responses to pathogensc involves both specific and nonspecific responses to pathogensd involves the production of external defences in response to pathogense involves very specific responses to pathogen

Which of the following best describes the role of the innate immune system in the human body?Group of answer choicesIt provides the body's first line of defence against foreign particles by recognizing specific pathogens and creating memory cells for future encounters.It primarily functions to produce antibodies that target specific pathogens the body has previously encountered.It consists only of white blood cells, which attack and destroy pathogens within the bloodstream.It recognizes and responds to pathogens non-specifically, providing an immediate response.
