1.
embryonic stem cells are pluripotent because they can
grow into any type of body cell, but they cannot become totipotent.
grow into any type of body cell.
grow into similar types of cells such as blood cells to blood cells.
2.
all muscle cells working together to produce working muscle tissue is an example of which theme of biology?
evolution
levels of organization
structure and function
unity and diversity
3.
based on the graph what can be concluded about stem cell banking?
~ihstbwgek1qzbk9lb. quunjkg_sn6jegik2zlkod/49371244,45a /assets/stem%20cell%20graph. jpg
from the years 1990 to 1995 is when there was the biggest jump in amount of stem cells banked
stem cell banking will start to decrease as scientist find ways to make artificial stem cells
the amount of stem cells being banked has increased over the past 25 years
banking stem cells will always increase

banking stem cells is a very popular practice in science. this is when stem cells, located in the umbilical cord of a birthed infant, are saved and frozen. why could this be a beneficial practice?
stem cells should not be saved because all cells of the body can be used as stem cells
stem cells are undifferentiated and therefore, could be used to grow into any kind of cell of the body
in case of an emergency, it is always good to have a lot of cells on hand since they cannot replace themselves
stem cells are already differentiated but can still replace different cells located in the body
5.
blood cells are different than nerve cells in how they look and what they do. why is this, since both of these kinds of cells are found in humans?
the cells have differentiated to perform different tasks within the organism
blood cells started out as nerve cells but changed shape due to their location
if blood cells were long like nerve cells they would get stuck in the blood vessels
blood cells undergo apoptosis in order to fulfill their role in the body
