Lipids serve as structural components of cell membranes, function as energy storehouses, and function as important signalling molecules. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.
Hope this helped :)
Answer: The staircase is 14.28 m high.
Explanation:
Given : Mass = 0.1 kg
Potential energy = 14 J
Potential energy is the energy occupied by the position of a substance. Therefore, formula for potential energy is as follows.
P.E = mgh
where,
m = mass
g = gravitational energy = 
h = height of object
Substitute the values into above formula as follows.

Thus, we can conclude that the staircase is 14.28 m high.
Solids— have tightly packed molecules, structured shape
Liquid— have no definite shape and the molecules are not tightly packed like a solid, they are a lot more loose.
Gas— No structure at all, molecules are free flowing
Sorry I couldn’t be a better help.. but I hope this gives you a bit of an idea :)
Well, Cellular Respiration does a lot for your body in many ways! It breaks down the sugars, fats, and proteins and gives your body the energy (ATP) it needs from that.
Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. Breeders select two parents that have beneficial phenotypic traits to reproduce, yielding offspring with those desired traits.
