The niche in the bone marrow has three important functions. pick the correct set of functions below.
a. specification, migration and stemness
b. self-renewal, proliferation and stemness/plasticity
c. proliferation, migration and differentiation
d. specification, determination and differentiation

B. Self-renewal, proliferation and stemness/plasticity.

Explanation:

The major role of the bone marrow cell is to produce the blood cells in the body. These cells are responsible for self renewal. These cells divide in large numbers so as to replace the dead and injured cells. These cells proliferate by dividing into numerous cells so as to perform the desired functional role.  The stemness and plasticity can be seen in bone marrow cells as these cells in adults can be molded into forms or shapes that they can perform a specialized function in the body.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
