<span>Earth consists of four major layers: the crust, mantle, outer core and inner core. While most of the layers are made of solid material, there are several pieces of evidence suggesting that the outer core is indeed liquid. Density, seismic-wave data and Earth’s magnetic field provide insight into not only the structure but also the composition of Earth’s core</span>

Other factors being equal, which sensory stimulus is least likely to lead to sensory adaptation?
valentina_108 [34]
The correct answer is: the wail of a loud car alarm. 
Sensory adaptation is a term that refers to the changes that stimuli can trigger on the sensory receptors. The process involves changes in the receptors' sensitivity and it is believed that all of the senses exhibit this adaptation. In particular, the sense of touch can quickly adapt to hot and cold stimulation, but not when the stimulus is extremely intense (such as too hot or too cold). Also, our olfactory sense presents the characteristic of odour fatigue. A prolonged exposure to a specific smell leads to a temporary inability to sense this smell and this is a type of sensory adaptation. Finally,
our hearing undergoes a sensory adaptation as well, but not when it comes to sudden, unexpected and instantaneous loud noises. That is why the wail of a loud car alarm will be the least likely to cause sensory adaptation.

Tresset [83]

Explanation:

Population density is the number of organisms are there in per unit area. It is used to measure geographical area occupied by organisms and its statistics.

In population ecology the structure, dynamics and contribution of population of species is studied. The idea of species distribution is studied in it.

The population density determines the number of species or members of particular population are present is a particular area.

An area of  low density population will have more resources and more area per organism and less competition for resources and vice versa for high density population.

Prairie dogs have 12 adults per hectare of area this tells the population density of the rodents.
