Answer:
25 years
Explanation:
Ossification is the process of bone tissue formation. Osteoblasts are responsible for the process of ossification. It begins when the fetus is three months old and goes on till 25 years of age. Upper limbs get ossified first, followed by lower limbs, sternum and vertebrae.
There are two types of ossification processes. When bone is directly developed using the primitive connective tissue (mesenchyme) it is called as intramembranous ossification, while in endochondral ossification cartilage is used as a precursor.
The prenatal circulation of blood is different than the postnatal circulation, mainly because the lungs are not in use. The fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord. Blood from the placenta is carried to the fetus by the umbilical vein.
Answer:
no difference
Explanation:
There is no difference between plant and animal glycolysis. Glycolysis is an important step of respiration and refers to the break down of glucose molecule for the generation of energy in the form of ATP. Both plant and animal glycolysis occurs in the cytoplasm of the cell where glucose molecule is broken down and produces 2 molecules of pyruvate and 2 molecule of ATP. This process occurs without the use of oxygen molecule.
