Abiotic factor means no living so your answer is water :)
All cells have a nucleus in the middle of it (Hope that helps)
The DNA of a human cell can be cut and rearranged by using Enzymes. To cut DNA into smaller segments, enzyme nucleases are used. They do this by taking the phsophodiester bonds through hydrolysis and catalyzing it. when these enzymes comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the molecule.
In the glomerulus, a tuft of capillaries in the renal cortex, blood is filtered through the porous capillary walls.

The glomerulus receives its blood supply (that need to be filtered) from an afferent arteriole of the renal arterial circulation and the glomerular capillaries exit into efferent arterioles. The glomerular filtration rate is a rate at which blood is filtered through all of the glomeruli.</span> </span>
When old red blood cells rupture, the released hemoglobin is ingested by macrophages
