enzymes and substrates
Squamous epithelium look like flattened cells that fit together like tiles.
There is an enzyme explanation whose specificity states that an enzyme and its substrate possess specific complementary geometric shapes that fit exactly into one another. This is the lock and key explanation.Ê
Enzymes have an active site that is specific for a substrate - therefore enzymes only work when the right substrate is present. The surfaces of the enzyme and the substrate fit together - like a lock and key - allowing the enzyme to fulfil its function. The theory of "induced fit" is more widely accepted - it is similar, but the enzyme shape changes to accommodate the substrate.
Epithelial cells
A binding site is the outer part of the protein that is folded into a unique shape. It has to have this certain shape, otherwise the enzyme and substrate will not fit together. This is called a "lock and key" mechanism.
Interlock
Hydrophilic substances incline to get together with polar substances like water or some ions while hydrophobic substances tend to get together with nonpolar substances like organic compounds. You can understand these identities by imagining that the more two substances are likely in polarity, the eaiser they get together, because they are fit in electic charges so that the energy of the mixture system is lower. Though this theory is rough, hope it can help you underdstand the the difference between hydrophilic and hydrophobic.
Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.
Thay fit together like a jigsaw puzzle
Squamous epithelium look like flattened cells that fit together like tiles.
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
They all fit together like a puzzle.
A map of the continents (with the exclusion of Antarctica and the inclusion of Greenland) is included in the link below and depicts how they would fit together today. They do not completely lock perfectly as their coasts have been eroded.

Puzzle pieces.
because when you cut the up the will fit together like a puzzle.
Equilateral triangles, squares, and regular hexagons(each fit together on its own/by itself)These are the only shapes that fit together on their ownYou can also make combinations like :octagons and squareshexagons and triangles
