Why would humans and other mammals evolve an allergic response that causes suffering, tissue damage, and even death?
Step by step
Solved in 2 steps
- What might be the evolutionary advantage of allergic reactions? (Hint: Are there harmful substances or organisms that might provoke allergic reactions?)The Human Immunodeficiency virus (HIV) cripples the specific immune response because HIV OA) directly destroys macrophages O B) directly destroys natural killer cells OC) directly destroys suppressor T cells OD) directly destroys helper T cells OE) All of the aboveWe talked in one of our first lectures about how we began to understand the potentiation of an action potential down an axon by stimulating and recording electrical changes in a giant squid neuron. Which neuroscience method enabled that discovery? Immunohistochemistry Electrophysiology Transgenic mouse lines Chemogenetics
- Bacteriophage is added to a culture of human T cells and none of the human T cells were infected by bacteriophage. Why? T cells do not have the proper protein machinery to carry out transcription and translation of bacteriophage genes. T cells do not have the corresponding cell surface receptors that are recognized by bacteriophage viruses. T cells have a thick outer cell wall that blocks bacteriophage infection. T cells do not carry out DNA replication and thus are not good hosts for the bacteriophage viruses.Immune systems of animals are very complex. For an animal's immune system to work properly, certain cells must be able to recognize other specific types of cells, so that they can bind to and communicate with them. These types of interactions allow an immune system to decide if and when to launch an immune response. For example, dendritic cells must be able to recognize and interact with T-cells, but they do not need to recognize adipocyte cells. Which of the following describes a difference between T-cells and adipocyte cells that would allow dendritic cells to recognize one, but not the other? A. Adipocyte cells must have a cell wall, while T-cells lack one. B. T-cells and adipocyte cells must have different types of lipids that compose their plasma membranes. C. Adipocyte cells must lack endoplasmic reticulum, while T-cells possess endoplasmic reticulum. D. T-cells and adipocyte cells must have some differences in the carbohydrates and/or…Which of the following is NOT one of the major functions of T lymphocytes (T cells)? activating the immune system binding to antigens presented by MHC proteins production of antibodies forming memory cells to more rapidly respond to future infections by the same pathogen attacking our own cells that are infected with a virus or cancerous
- What is the role of T cell, B cells, and Natural killer cells in the function of the Immune system?1) Ahh! COVID Zombies are attacking us and we have to run for our lives! This means our _________ is activated. Group of answer choices Sympathetic nervous system Parasympathetic nervous system Endocrine system Immune system 2) ou walked into your little sister’s room and it smelled strongly of marijuana smoke. You noticed it right away. After a few minutes, though, you stopped noticing the smell. This best illustrates: Group of answer choices Priming Transduction Schemas Sensory adaptationWhy is innate immunity referred to as nonspecific? because it is a form of defense found in all animal species because it provides defense against a wide range of pathogens because it is a form of defense that functions in all human body systems because it provides a built-in mechanism of defense that does not require "training"
- Why is there a need for dogs to be vaccinated ?Which of the following is not true for a natural killer cell? A) do not undergo rearrangement of receptor genes B) develop in the thymus c) stimulated (activated) by IFN-a and other cytokines D) lack of NK cells can lead to severe viral infections Question 6 Represents innate immune system receptors A Randomly arranged B) Germline encoded c) cross-reactive D) CLP encoded is determined by specific carbohydrate groupsHay fever, also called allergic rhinitis, is a common ailment in the spring. People who experience hay fever have sensitive immune systems that respond to pollen in the air. When pollen, the allergen, enters the airways, the inflammatory response is triggered, even though pollen is not a dangerous molecule. Symptoms include inflammation of the airways, nasal congestion, and watery eyes. While there is currently no cure for hay fever, people suffering from it often take antihistamines, medications that inhibit the action of histamine. How would this help the condition?
