    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.

  • Science - ,

    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?

  • Science - ,

    Yes 1. By attaching to them
    2. Active Immunity
    3. All of the above
    4. Antibodies
    5. Antigens


    They are all correct

  • Science - ,

    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

  • Science - ,

    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.
