<span>I suspect this question should read "How long does a red blood
cell live." A red blood cell lives for between 100 and 120 days. It
takes 7 days for a new red blood cell to develop from stem cells. Stem
cells are similar to base cells. They can also be seen as a general
template from which specialized cells are made. Stem cells can be taken
from a newborn baby's umbilical chord or extracted from an adult blood
donor's blood.</span>
Without further context I would assume the answer here is: Hydroxyl groups.
Answer:
monosaccharides
Explanation:
<em>The monomers of polysaccharides are the monosaccharides, otherwise known as the simple sugars. The monosaccharides are linked together by bonds known as glycosidic bonds. </em>
For example; starch, cellulose, and glycogen are polysaccharides whose monomer units are glucose - a monosaccharide. The glycosidic bonds in starch and glycogen are alpha while those in cellulose are beta glycosidic bonds. The latter is formed when the hydroxyl group on the first carbon of the sugar is above the glucose ring while the former is formed when the hydroxyl group is below the ring.
It prevent
an action potential if it blocks the movement of sodium across the membrane. The
primary feature of a neuron that prevents the action potential from traveling
back from where it just passed is the absolute refractory period. It holds an
action potential if it blocks the movement of sodium across the membrane.
Answer:
I would say the vacuole
