What is intramembranous ossification? what is intramembranous ossification? the formation of bone from preexisting fibrocartilage models the formation of bone from fibrous membranes the formation of bone from preexisting hyaline cartilage models the formation of bone from preexisting elastic cartilage models?

Option B, models the formation of bone from fibrous membranes

Explanation:

In the process of Intramembranous ossification, Fetal develops to form skeletal system by replacing fibrous membrane. The mesenchymal tissue is  converted into a bone directly.  This generally happens in the bones of skull. In other ossification processes, fibrous membrane is converted into cartilage and then it is replaced by bone as in the case of endochondral ossification, where bone develops by replacing hyaline cartilage.

Hence, option B is correct.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
