Both are large, rocky bodies in space but asteroids tend to stay in the asteroid belt, while meteoroids are a bit smaller and more active.
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:
The density will increase
Explanation:
As mentioned in the question, the lamp contains a colored, waxy fluid that can be observed moving in clumps through a clear liquid. The clump of colored fluid reaches to the top from the bottom of the lava lamp, this happens because the clump is heavier so it will absorb maximum amount of heat and using that heat it will expand. When things expand they become less dense and start to rise. So,initially its density will lower but when it will keep rising in such a way that when it reaches top, it becomes more dense and heavy since it has cooled down till that time.
Hope it help!
