Answer: i think, Endochondral ossification occurs at two distinct sites in the vertebrate long bone – the primary (diaphyseal) and the secondary (epiphyseal) sites of ossification. Bone development initiates at the primary site. The secondary (epiphyseal) site is under independent control and is ossified later (Figure 1b).
Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
When an energy source is renewable it is able to be continuously used without end and it usually does not harm the environment. <span />
