The only known infectious agents that lack genetic material are A. certain viruses. B. prions. C. viroids. D. none of the above D?
The only known infectious agents that lack genetic material are prions. Prions are misfolded proteins that can cause other proteins to misfold and aggregate, leading to neurodegenerative diseases such as Creutzfeldt-Jakob disease.
Who discovered prions?
Stanley B. Prusiner discovered prions in the 1980s. He was awarded the Nobel Prize in Physiology or Medicine in 1997 for his discovery of these infectious proteins, which can cause neurodegenerative diseases.
Why dont blood cells and antibodies from the immune system try to destroy the toxic prion proteins?
Prions are abnormally folded proteins that are not recognized as foreign by the immune system, so there is no immune response targeted against them. Additionally, prions are not associated with pathogens like bacteria or viruses that would trigger an immune response. As a result, the body does not mount an immune response to destroy the toxic prion proteins.
Which class of fires consists of flammable liquids including stove alcohol, gasoline?
Class b
How prion discovered?
Prions were discovered in the 1980s by Stanley B. Prusiner, who received the Nobel Prize in Physiology or Medicine in 1997 for his work. He coined the term "prion" to describe the infectious agent responsible for diseases like scrapie in sheep and Creutzfeldt-Jakob disease in humans. Prions are unique in that they are made up of abnormal proteins that can induce normal proteins to misfold and aggregate, leading to neurodegenerative diseases.
What Nobel Prize did Stanley B. Prusiner win?

Examples of inheritance in c plus plus?
Single-inheritance is where one class inherits directly from another class: class A {}; class B : public A {}; Here, class B inherits all the public and protected members of class A. Multiple-inheritance is where one class inherits directly from two or more classes: class A {}; class B {}; class C : public A, public B {}; Here, class C inherits all the public and protected members of both A and B. Multi-level inheritance is where one class inherits from another class that itself derived. class A {}; class B : public A {}; class C : public B {}; Here, class B inherits all the public and protected members of A while class C inherits all the public and protected members of B, including those inherited from A. Virtual inheritance applies to multi-level inheritance whereby a virtual base class becomes a direct ancestor to the most-derived class. This variation of inheritance is typically used in multiple inheritance situations where two or more intermediate classes inherit from the same base class: class A {}; class B : public virtual A {}; class C : public virtual A {}; class D : public B, public C {}; Here, classes B and C both inherit from class A. Without virtual inheritance this would mean class D would inherit two instances of A (B::A and C::A), thus creating ambiguity when referring to D::A. By employing virtual inheritance, D inherits directly from A, and both B and C inherit from D::A. In other words, B and C share the same instance of A. Another use of virtual inheritance is when you need to make a class final. class A; class B { friend class A; B() {} // private constructor }; class A : public virtual B { }; Here, class A is the final class. Class B is a helper class that has a private constructor while class A is declared a friend of class B. Class A is therefore the only class that can inherit from class B as it is the only class that can construct objects from class B. However, by inheriting class B virtually, we ensure that no other class can be derived from class A because virtual inheritance ensures that the most-derived class must be able to construct a class B object first. Currently, only class A has that privilege and must always be the most-derived class.
What is a concrete class?
not class B
How do you call a member function of one class in another class using friend function?
class B; // forward declaration. class A { private: void myFunction(B b){b.myFunction();} // Calls private method in b. }; class B { friend void A::myFunction(B b); // Friend function declaration. private: void MyFunction(); };
What do class b fires consist of?
Class B extinguishers fight Flammable Liquid fires. The extinguisher classes: Class A: flammable solids Class B: flammable liquids Class C: fires involving electrical equipment. These agents don't conduct electricity. No extinguisher is rated as only for Class C fires; you will find Class B-C and Class A-B-C extinguishers. Class D: flammable metals Class K: kitchen fires
