Monomers bind chemically to other molecules to form polymers
I think its acid fermentation, but I could be wrong. My class studied this a while ago.
Well, we are all made differently because we have different DNA.
The correct answer is option b. They receive instructions in their DNA.
The DNA (deoxyribonucleic acid) or the genes present in the cell guides the fate of the cells during the process of cellular differentiation in the embryonic life of the multicellular organism. The signaling molecule change the genetic expression changes, by which the cells are differentiated.
The shoulder (pectoral) and pelvic girdles are both structures for limb articulation. The shoulder girdles are to the upper limbs as the pelvic girdle is to the lower limbs. Shoulder girdles connect the upper arms with the axial skeleton and consist of the clavicle and scapula.
The pelvic girdles consist of the hip bones, the sacrum and the coccyx and are located between the abdomen and the thighs.
