The model in the image justifies this statement that the body carries out critical life functions through systems of specialized cells like Nerve cells, blood cells, and reproductive cells.
Step-by-step explanation:
Steroid hormones are derived from cholesterol responsible for the regulation of a wide range of physiological functions.
DNA is a self-replicating material which is present in maximum living organisms as the main integral part of chromosomes. It acts as a carrier of genetic information.
This hormone consist of a different cell, which is getting extracted by another cell through a steroid receptor.
Ribosomes, also known as protein builders are minute particles consisting of RNA. Proteins are needed for several cellular functions like repairing damage or controlling chemical processes. These functions would be impossible without the help of all specialized cells.
