No, multiplying or dividing mass and volume by the same factor will not affect density because density is calculated by dividing mass by volume. As long as the mass-to-volume ratio remains constant, the density will not change.
Yes, packing factor does affect density. Packing factor refers to how closely atoms are packed in a material, which in turn influences the material's density. Materials with higher packing factors will have higher densities because the atoms are more closely packed together.
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.
The density dependent factor refers to the factors that affect the size or growth of a given population density. The factors also affect the mortality rate and the Birth Rate of a population. Some of the density dependent factors are disease, parasitism, availability of food and migration.
A density-dependent factor is a variable that affects a population's growth based on its density. Among the options provided, fire is considered a density-dependent factor because its impact can vary with the population size; for example, in a dense forest, a fire can spread more easily and affect more individuals. In contrast, wind and flood are generally density-independent factors, as they affect populations regardless of their density.

An example of a density-dependent factor is competition for resources, such as food or space, which becomes more intense as a population increases, potentially leading to decreased growth rates or population decline. Conversely, a density-independent factor is a natural disaster, like a hurricane or wildfire, which can affect a population's growth regardless of its size by causing widespread mortality or habitat destruction. Both factors can significantly influence population dynamics, either by limiting growth as density increases or by causing sudden declines irrespective of population density.
Seasonal cycles can impact population dynamics, but they are not considered a density-dependent limiting factor. Density-dependent factors depend on the population size, such as competition for resources or predation. Seasonal cycles can affect populations through environmental changes like temperature or precipitation variations.
When you multiply both the mass and volume of an object by the same factor, you are essentially scaling the entire object uniformly. Since density is calculated as mass divided by volume, when you multiply both the mass and volume by the same factor, the ratio between them remains the same. As a result, the density of the object remains unchanged.
Density-independent limiting factors do not typically affect small scattered populations as much, as they are not dependent on the population size or density. Examples include natural disasters like hurricanes or forest fires.

A density dependent factor is a limiting factor that depends on population size. A Density-independent limiting factor affects all populations in similar ways, regardless of the population size. Its in my biology book.
