Agroup of students are reviewing information about the skeletal development in children. the students demonstrate understanding of the information when they identify that ossification is complete by what age?

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.

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
