Cells with cell chemicals and genetic material having no defined organelles and are all enclosed within a cell wall are called prokaryotes. Organisms in this group are small in size and are mainly bacteria. Ribosomes in these small cells are also small and ‘free floating’. DNA in prokaryotic cells is in the form of a circular strand and not as a chromosome.
Have an awesome day! :)
<span>Similarities and differences between intramembranous and endochondral ossification<span>
Ossification is the process of bone formation. Intramembranous and endochondral ossification are the two main processes of bone formation that occur during fetal development.
</span>Similarities between intramembranous and endochondral ossification<span>; they turn cartilage into bones during bone formation and they both involve bone cells such as calcium, vascular supply and osteoblasts.
</span>Differences between intramembranous and endochondral ossification<span>; In intramembranous ossification, an intermediate cartilage is not involved, rather the bone tissue is directly laid on a primitive connective tissue called mesenchyma while in endochondral ossification, cartilage is used as a precursor for bone formation. Also, in cases of fractures, the healing process by plaster of Paris occurs through endochondral ossification while fractures which are treated by open reduction and internal fixation are healed by intramembranous ossification.

Explanation:
Anabolism requires energy to grow and build. Catabolism uses energy to break down. These metabolic processes work together in all living organisms to do things like produce energy and repair cells.
Catabolic reactions release energy, while anabolic reactions use up energy.

Hi this would be called the blind spot. Hope this helps.
