i just took the test!
2. Is acquired immunity. I have no idea where you picked that up from.
A simple google search for active immunity will confirm this:
Immunity obtained either from the development of antibodies in response to exposure to an antigen, as from vaccination or an attack of an infectious disease, or from the transmission of antibodies, as from mother to fetus through the placenta or the injection of antiserum.
I gave you the definition of acquired immunity.
Um , please guys
I need the right answer. I'm taking the test to. The name " the right answer" can you give me the right answers that were correct on the test?
Yes 1. By attaching to them
2. Active Immunity
3. All of the above
4. Antibodies
5. Antigens
They are all correct
Yes 1. By attaching to them
2. Active Immunity
3. All of the above
4. Antibodies
5. Antigens
They are all correct also I have something for you
1. According to the MLA style how should you format the title of a magazine article please I need help has any one did this I need the correct answer! Thankyou
Okay, I think I see what is causing the confusion. Both answers are correct, but for this particular test/quiz online, I can not be certain, and it depends on how the information was presented to you. In science words are constantly changing, especially in the life sciences. A new term that scientist like to use is called active-acquired immunity, which means the same thing as acquired immunity or active immunity.
The official definition for acquired immunity is, "Immunity obtained either from the development of antibodies in response to exposure to an antigen, as from vaccination or an attack of an infectious disease, or from the transmission of antibodies, as from mother to fetus through the placenta or the injection of antiserum."
The official definition for active immunity is, "a type of immunity or resistance developed in an organism by its own production of antibodies in response to an exposure to an antigen, a pathogen or to a vaccine."
As you can see, both definitions are essentially the same, but acquired immunity can be broken down into two different groups: active acquired immunity and passive acquired immunity. The difference between the two has to do with how long the effects and how they are acquired with regards to the immune system. Passive acquired immunity's effects are short term and are acquired from a source besides the host, whereas active acquired immunity's effects are long and are acquired in the host.
I hope this helps.
1. Antibodies make antigens useless by attaching to them. Antibodies are Y-shaped proteins produced by the immune system in response to the presence of antigens. When antibodies encounter antigens, they bind to them specifically, forming an antigen-antibody complex. This binding can prevent antigens from interacting with other cells and molecules in the body, neutralizing their harmful effects.
2. "Acquired immunity" occurs when your body already contains antibodies against an infection due to previous exposure. Acquired immunity is a type of adaptive immunity that develops over time as a result of exposure to pathogens or vaccination. It involves the production of antibodies and memory cells that can recognize and respond more effectively to specific antigens upon subsequent encounters.
3. Passive immunity is best described as short-term protection that is passed from mother to baby, or when forms of immunity developed in another animal are introduced into your body. Passive immunity is acquired through the transfer of pre-formed antibodies from an external source, rather than being produced by the individual's immune system. It provides immediate but temporary protection against specific pathogens.
4. White blood cells produce antibodies that immobilize pathogens. When the immune system detects the presence of pathogens, certain types of white blood cells, known as B cells, are activated and undergo a process called antibody production. B cells produce antibodies, which are then released into the bloodstream, allowing them to bind to and neutralize the pathogens, preventing their further spread and immobilizing them.
5. When your body fights against disease, it is battling against antigens. Antigens are substances that can induce an immune response in the body. They are usually foreign molecules, such as proteins or polysaccharides, derived from pathogens or other foreign entities. When antigens enter the body, they are recognized by the immune system, triggering an immune response that aims to eliminate or neutralize the antigens to protect the body from the associated disease or infection.
