<span>The reason behind the lipids which are able to function as protective barriers in cells is that lipids do not dissolve in water.
If lipids dissolve in water, they will not be able to function as protective barriers in cells. N</span><span>ucleic acids, proteins, lipids and carbohydrates are the four types of macro-molecules in the cell.</span>
Accumulating physical activity experiences is the key to improve our physical activity performances.
Basically, a droplet of water falls, freezes, and is blown back up over and over and over again without hitting the ground. Each time it keeps accumulating more water droplets that keep freezing to the growing hail stone. That's how all hail is formed. When the hail stone is too big for the winds to keep blowing it back up again, it falls. The stronger the updrafts, the bigger the hail will get before falling to the ground. That's why it takes a pretty powerful storm to make a big hail stone -- the winds have to be strong enough to blow an almost baseball-sized piece of ice back upward again for it to keep growing.

Explanation:
Simulation is imitating a process. It is doing exactly like a system will do. It can be used in technologies, education, health, training,
safety engineering. Simulation can be used when the original or exact system is not in place, or cannot be accessed.
A model is a process that helps to understands a system. A model is like an example to follow in achieving a result. A model may not be followed judiciously such that you may require an aspect of the model and then use but not necessarily all attributes while a simulation does exactly what the system does.
