An ideal gas is one in which the gas molecules do not
interact with each other, hence intermolecular forces of attraction is
negligible. For this to occur, the pressure must be low and temperature is high
so that the volume or space between molecules is very large. This can be taken
from the ideal gas equation:
PV = nRT
where an increase in temperature and decrease in pressure
makes the volume increase
<span>So a noble gas other than radon which would depart most
readily from ideal gas behaviour must have also a high density. From the
tables, this would be Xenon.</span>

Answer:
The protein products of proto-oncogenes regulate the processes of cell division and growth.
Explanation:
The proto-oncogenes are the genes that code for the proteins involved in the regulation of cell division, growth, and differentiation. Certain mutations in these proto-oncogenes transform them into the oncogenes.
For example, the "erbB" gene code for receptor of epidermal growth factor which in turn regulates cell division in epidermal cells. The mutated erbB oncogene code for truncated receptor for epidermal growth factor which in turn makes the cell to divide continuously.
Hence, the proto-oncogenes are required by cells to regulate the processes of cell cycle, growth, and differentiation.
Epiphytes show commensalism.
