The answer relates to the medium in which the sensed molecules travel. On land, animals detect a scent through organic molecules transported in the air. Land animals will experience a taste sensation by grasping an object using their mouth. Here, the organic molecules providing the sensation are transported by saliva or organic fluids of the object. So on land, there is a clear distinction between molecules transported in the wind and those that can be tasted. Water is a much more dense medium than air, and can carry small and large organic molecules, unlike air. Therefore, aquatic animals have little need for olfactory organs as all molecules can be 'tasted' from the water.
Answer:
Explanation:
A root has an outside layer, the epidermis, and a central cylinder of a vascular tissue. Between these two tissues lies a large area of ground tissue.
Answer: decreases with decreased
Explanation:
Altitude is height above sea level.
The density of air decreases with height.
At higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center.
So at higher altitudes, air molecules can spread out more, and air density decreases
