Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart
disease
Evaluate the use of stem cells from embryos or from adult bone marrow for treating
human diseases

Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox
and measles. What is responsible for this lifetime immunity?
The innate immune response, because barriers to entering the body improve with age.
The innate immune response, because adults have more white blood cells than children.
The acquired immune response, because antibodies are developed from previous infections.
The acquired immune response, because it responds rapidly to broad classes of pathogens.
The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.
The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.
The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.
Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.
Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).
