Which process allow you to smell perfume at a distance from the source? a. diffusion b. osmosis c. homeostasis d. selective permeability

a. diffusion

Explanation:

It is diffusion which allows us to smell perfume at a distance from the source. Diffusion is a natural phenomenon which occurs when there is a concentration gradient in the molecules of a gaseous substance. The molecules tend to move passively from a place where gradient is higher to a place where gradient is lower by the process of diffusion. This movement continues unless the concentration of molecules become equal at both the places. At this time, an equilibrium is said to be attained and there is no net movement.

In this example, when a bottle of perfume which is source is opened at a distantly located place at that time the concentration gradient of perfume molecules is greater at that place while at a distantly located place where we are standing there are no perfume molecules i.e. concentration of perfume molecules is low . Since there is a gradient so molecules will start to move from source towards us because movement is supposed to be from higher to lower gradient. As a result of which the perfume molecules will reach us by the process of diffusion and we are able to smell the perfume.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
