What is intramembranous ossification? a. the formation of bone from preexisting hyaline cartilage models b. the formation of bon
e from preexisting elastic cartilage models c. the formation of bone from within fibrous membranes d. the formation of bone from preexisting fibrocartilage models
c. the formation of bone from within fibrous membranes
Explanation:
On the basis of formation ossification process is divided into two types:
1) Endochondral ossification : The process by which bone is formed from haline cartilage.
2) Intramembranous ossification : The process by which bone is formed by replacing a fibrous membrane and not from cartilage. This type of ossification occurs as follows :
An ossification center appears in the fibrous connective tissue membrane.
Bone matrix is secreted within fibrous membrane
Woven bone and periosteum forms.
Bone collar of compact bone forms and red marrow appears.
Hence option c. the formation of bone from within fibrous membranes is the right option
The folds contain ribosomes attached to the membrane. The more the folds the more the surface area to which more ribosomes can attach. The ribosomes are organelles responsible for the manufacture of protein in cells. Thereafter, the proteins are properly folded by the mediation of chaperones in the lumen of the RER.
to determine whether traits can be inherited independently
Explanation:
the use of dihybrid crosses allowed him to discover the law of independent assortment / discovering that each locus had 2 alleles which segregate during the creation of gametes.
Explanation: The basic unit of a DNA is a Nucleotide. The nucleotide comprises of: the nitrogenous bases, a deoxyribose sugar and a phosphate group. The nitrogenous bases are the purines and pyrimidines . The include, Adenine, guanine, Thymine and cytosine
