What are examples of artificial active immunity?
Active immunity is acquired from vaccinations or from infection against a pathogen. The next time you encounter the same pathogen your body has built memory against it and will be able to fight it much more efficiently. Passive immunity is primarily through a mother to a baby or fetus. Through the placenta the mother transfers her immunity (IgG antibodies) to her fetus. Also through breast milk she can although the placenta is much more so. The baby has her/his immunity from the mother but it only lasts a few months because the baby hasn't developed his/her own immunity.
What happens during germinal stage and how long does it last?
The germinal stage is the first stage of prenatal development that begins at fertilization and lasts for about two weeks. During this stage, the zygote undergoes rapid cell division and travels down the fallopian tube to the uterus, where it implants in the uterine lining. The germinal stage ends with the formation of the blastocyst, which is the early stage of embryonic development.
Can implantation bleeding last 2 weeks?
Yes it is possible. It varies from woman to woman so in some cases it can last 1-2 days and only a drop of blood or it can last up to 2 weeks (9-13 days) and can have a light flow to it. Just depends on your body.
What is the Differentiate between Humoral mediated immune response and cellular mediated immune response?
The difference between humoral immunity and cell-mediated immunity is that humoral immunity uses B cells and T cells whereas mediated immunity only uses the T cells. Also humoral immunity provides a defense against antigens and pathogens in body fluids whereas cell-mediated immunity protects from abnormal cells and pathogens inside living cells.
What is a Monarch Butterfly Chrysalis made of?
A Monarch Butterfly chrysalis is made of hardened protein called chitin, which is secreted by the caterpillar as it forms the protective outer layer during the pupal stage. Inside the chrysalis, the caterpillar undergoes metamorphosis, transforming into a butterfly.

Compare passive immunity to active immunity?
Active Immunity - Vaccines are used for health purposes to expose our bodies to a particular antigen. These antigens are usually killed or severely weakened to decrease their potency. After destroying these pathogens, the body stores some T cells as memory cells, due to the fact they code for a particular antigen and can be when needed. This memory in T cells can be a means of artificially acquiring immunity while a genuine attack by a pathogen is a naturally acquired type of immunity. Passive Immunity - This is where immunity to particular antigens as a result of genetic traits passed on from parents rendering the offspring immune to a particular pathogenic threat.
