A) Why is mitosis a longer and more complicated process of cell division than binary fission?
(1 point)
Binary fission does not replicate DNA
Mitosis occurs in the cytoplasm and does not require a nucleus
Mitosis has check points that must be met to continue the cycle
Binary fission produces two identical daughter cells
C) Mitosis has check points that must be met to continue the cycle
A) Some differentiated cells become senescent almost immediately, leaving the cell cycle and
undergoing terminal differentiation. Other cells have a high need to proliferate in order to grow
and repair the organ or tissue, so they do not enter senescence for a long period of time.
Which cell type would be most likely to put off senescence and terminal differentiation so it
could continue to replicate in order to grow and repair? (1 point)
skin cells
lung cells
brain cells
heart cells
The most likely cell type to put off senescence and terminal differentiation to continue replicating would be skin cells.
A) When scientists and doctors are looking to heal wounds and cure diseases, stem cells are a
great option because they can repair damage and grow new specialized cells. From the list,
which type of stem cell would be the best option for healing the widest variety of diseases?
(1 point)
skin stem cells
bone marrow stem cells
small intestine stem cells
embryonic stem cells
