Answer:
c. Ribosomes
Explanation:
Ribosomes can be found in eukaryotic and prokaryotic cells. In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm. In both cells, ribosomes intertwine into an RNA molecule and form polysomes.
Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.
Answer;
-Ossification (growth) centers
Explanation;
-Ossification is the process of bone formation by osteoblasts. Ossification is distinct from the process of calcification; whereas calcification takes place during the ossification of bones, it can also occur in other tissues.
-Primary ossification center is the first area of a bone to start ossifying. It usually appears during prenatal development in the central part of each developing bone. The secondary ossification centers appear, during the first years of postnatal life, in the epiphyses of the bone (at the ends of the bone).
