What is the main difference between bacteria and viruses?

Detailed Solution for Test: Biotechnology - 10 - Question 1
Bacteria can reproduce independently without a host, while viruses require a living host cell for replication. This is a fundamental difference between bacteria and viruses. Bacteria are single-celled organisms capable of independent survival, whereas viruses are obligate intracellular parasites, meaning they cannot replicate without a host cell. This distinction is crucial in understanding their behavior and how they cause infections.

What is the primary role of vaccines?

Detailed Solution for Test: Biotechnology - 10 - Question 3
The primary role of vaccines is to provide active acquired immunity against specific diseases. They achieve this by exposing the immune system to harmless parts of disease-causing microorganisms, such as proteins or weakened viruses, which stimulate the production of antibodies. This prepares the immune system to respond effectively if exposed to the actual pathogen in the future.

Which type of vaccine uses weakened forms of disease-causing microorganisms?
Detailed Solution for Test: Biotechnology - 10 - Question 4
Inactivated vaccines use pathogens that have been killed or inactivated, typically through heat or chemicals, while keeping the pathogen's structure intact. This allows them to trigger an immune response without causing the actual disease. This is a common approach in vaccine development.

What is the advantage of mRNA vaccines over traditional vaccines?
Detailed Solution for Test: Biotechnology - 10 - Question 5
mRNA vaccines have an advantage over traditional vaccines in that they stimulate both the antibody response and cellular immunity. This broader immune response can enhance protection against the virus. Traditional vaccines typically focus on the antibody response alone.

What do viroids consist of?
Detailed Solution for Test: Biotechnology - 10 - Question 6
Viroids consist solely of a single, free RNA molecule and do not have a protective protein coat. They are one of the simplest known pathogens and are characterized by their small size and RNA composition.

What is the main reason why viruses are not classified as true living organisms?
Detailed Solution for Test: Biotechnology - 10 - Question 7
Viruses are not classified as true living organisms because they require a living host cell to replicate and reproduce. They are obligate intracellular parasites, depending on host cells for their replication and propagation.

What is the purpose of antibodies in the immune system?
Detailed Solution for Test: Biotechnology - 10 - Question 8
Antibodies are blood proteins produced by the body in response to antigens, and their primary purpose is to neutralize or eliminate antigens (foreign substances) recognized by the immune system. They play a crucial role in defending the body against infections.
Test: Biotechnology - 10 - Question 9

What is the term for immunity developed over a lifetime through vaccination, exposure to a disease, or receiving antibodies from another person?
Detailed Solution for Test: Biotechnology - 10 - Question 9
Active acquired immunity is developed over a lifetime through vaccination, exposure to a disease, or receiving antibodies from another person. This type of immunity involves the immune system learning to target and create antibodies against specific pathogens.
