According to evolutionary theory, this competition within and between species for resources is important in natural selection. However, competition may ... Competition can cause species to evolve differences in traits.
The fluid-mosaic model describes the plasma membrane of
animal cells. The plasma membrane that surrounds these cells has two
layers (a bilayer) of phospholipids (fats with phosphorous
attached), which at body temperature are like vegetable oil (fluid).
And the structure of the plasma membrane supports the old saying, “Oil
and water don’t mix.”
Each phospholipid molecule has a head that is attracted to water (hydrophilic: hydro = water; philic = loving) and a tail that repels water (hydrophobic: hydro = water; phobic
= fearing). Both layers of the plasma membrane have the hydrophilic
heads pointing toward the outside; the hydrophobic tails form the inside
of the bilayer.
Because cells reside in a watery solution (extracellular
fluid), and they contain a watery solution inside of them (cytoplasm),
the plasma membrane forms a circle around each cell so that the
water-loving heads are in contact with the fluid, and the water-fearing
tails are protected on the inside.
Answer:
One of the most famous water towers in Illinois is the Chicago water tower built in 1869 by William W. Boyington. The huge tower was built to pump water from Lake Michigan. This tower is a very rare tower because it is also one of the few towers to survive the great chicago fire in 1871.
