Answer:
The hardness rating is 4.
Explanation:
Calcite sits at a hardness rating of 3 and is very easily scratched with a knife and/copper coin. This is where most Marbles, limestones, travertines, rate.
Meanwhile, Fluorite sits at hardness 4 and can be scratched by a knife.
Answer:
Emulsifier generally reduces the surface tension of the lipid there by helping in the digestion of the lipid molecules.
Explanation:
Bile that is secreted from liver act as emulsifier because the bile helps in the break down of lipid into small molecules to form micelle thereby reducing the surface tension of the lipid molecules.
Due the formation of micelle the broken down lipid molecules binds to the active site of the lipase enzyme and get digested to form fatty acid and glycerol.
Beside digestion Emulsifier Bile also helps in the absoption of lipid from the small intestine.
Animals such as bees or wind can carry pollen from one flower to another flower and fertilize the plant that way. Plants can also self-pollinate which happens when a plant’s own pollen fertilizes its own ovules.
As when things get eaten some of the energy is lost the predators have to have more than one prey to survive, this means there is only a limited amount to be shared which means less predators
<span>The process when molecules tend to move from an area of high concentration to an area of low concentration is diffusion! I hope I helped :D</span>
