It is hard to understand this question but ill give you my best answer. The hearts level of organisation to cells is immense, the heart pumps blood to every cell in the body (so they can respire) through a system of Arteries, veins and capillaries. The blood is pushed by the force of the heart through the arteries, the main (and largest) tubes for transportation to segments of the body further away from the heart. This goes into a smaller system of veins that brake off into a tree kind of pattern to reach every cell. These later brake off into the capillaries that have walls only 1 cell thick. This is how blood is transported to each cell that requires energy and oxygen to respire.
The hedgehog are animals with spiny armor that protects it from predators and cushions its falls from trees. Animals have different survival mechanisms and means to protect themselves from possible predators. For example; a Camel has long eyelashes and hair-lined ears that blocks blowing sand, can close its nostrils to keep sand out. Others like Koala uses specially designed hands and feet and a thick, padded tail to hold on to tree branches for long periods of time.
Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.
