Hey Friend :-)
Here is your answer
Not every cell in the human body contains DNA bundled in a cell nucleus. Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus.
As part of the maturation process, human red blood cells destroy their cell nuclei. They do this in order to carry as much oxygen as possible and still stay small enough to fit through narrow blood capillaries, thereby maximizing the oxygen delivery. In fact, humans have some of the smallest red blood cells of all vertebrates, thanks in part to the destruction of the nucleus. Most mammals have red blood cells without nuclei, while all other types of vertebrates do have nuclei in their red blood cells.
Human red blood cells simply destroy their nucleus once it is no longer needed as part of the maturation process. A ring of actin within a maturing red blood cell pinches and splits the cell into two parts: one part with the DNA and one part without. Red blood cell enucleation is therefore a special type of cell division. Macrophages then come along and gobble up the parts containing DNA, leaving only the red blood cell parts that don't have DNA.
Conclusion: They do this in order to maximize the space in the cell to carry larger amounts of oxygen.
Hoping it helps
Thanks :D

You have done copy paste. In first I tried in google but I didn't understand. that's why I put it in brainly
it is given in the question that particles moving with uniform velocity is equal to x is equal to zero x is equal to X not b is equal to be known and equal to a note Then extra graph in excel graph show the constant rusty button second case particle moving with uniform velocity in x-t graph please explain me what is the meaning of uniform acceleration and uniform velocity in both the cases
