Answer:
Option (4).
Explanation:
Signal transduction may be defined as the process by which the physical or chemical signal can be transmitted in the body by the series of the different molecular events. Proteins kinases are important for the signal transduction pathway.
The signal transduction pathway occurs in the early as well as in the modern life. Molecular techniques has provided the evidence that cell signalling process is quite similar in the common ancestors and modern organism. Some biochemical molecules are similar that takes part in the signal transduction pathway.
Thus, the correct answer is option (4).
Yes, it is. This is because the water from the ocean evaporates under sunlight, forming part of the clouds, and then rain falls from the same clouds back into the ocean.
The functions of the integument include resident macrophage-like cells that ingest foreign invaders and present them to the immune system.
<h3>What is the integumentary system?</h3>
The integumentary system is a physical barrier that separates the body from the external environment.
This barrier (integumentary system) is fundamental for the immune system due to the presence of macrophage-like cells.
In conclusion, the functions of the integument include resident macrophage-like cells that ingest foreign invaders and present them to the immune system.
