In radiology, the standard units of measurement include millimeters (mm) for lengths, centimeters (cm) for larger lengths or dimensions, and Hounsfield units (HU) for measuring the density of tissues in a CT scan. Additionally, gray (Gy) and sievert (Sv) are used to measure radiation dose in radiology.

A density dependent factor is a factor that is affected by the amount of organisms in a population. An example of this would be sickness, as the higher the density is, the more easily the sickness will spread.
The question is ambiguous, controlling factor of what? Specific gravity will change according to temperature (all other things being equal) Salinity will not change with temperature. Water will is most dense at about 4 degrees Celsius, and will become less dense at higher and lower temperatures (to a point)
An earthquake-related tsunami is a density-independent factor because it can affect populations regardless of their size or density. Tsunamis are triggered by geological events such as earthquakes and have the potential to impact ecosystems and populations regardless of their size.
A density-dependent factor is one where the effect of the factor on the size of the population depends upon the original density or size of the population. A disease is a good example of a density-dependent factor. If a population is dense and the individuals live close together, then each individual will have a higher probability of catching the disease than if the individuals had been living farther apart. Not only will a greater number of individuals be affected, but, more importantly, a greater proportion of the population will be affected if they are living close together. For example, bird populations are often regulated more by this type of regulation.
