Serous Membranes
animal?? obviously animal, I have read this q? several times and your poor phrasing grammar is making it that bit more difficult to answer but I think the answer u are after is....Visceral Membranes line the bodies internal organs, eg.Lungs. Parietal Membranes line the bodies internal Cavities (spaces) eg.the surface of the inner part of the Rib-Cage. Where these 2 membranes meet there will be a certain friction, but to overcome this friction the body has cleverly placed another membrane called a Serous Membrane which descretes Serous Fluid to act as a lubricant. ie.the Lungs can freely expand beneath but over the Rib-Cage surface without getting stuck. Hope this is of help
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.
Colder temperatures can cause friction on surfaces to decrease as it can make surfaces more smooth and slippery. Rain or wet conditions can also reduce friction due to the presence of moisture on the surface. Additionally, icy or frosty conditions can lead to a decrease in friction as the ice or frost can create a slippery surface.
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.

use lubricants it smoothens the surface and reduces the irregularity between both the surfaces resulting in reduction of friction
If both of the surfaces on which friction is to be created are very rough, the friction will be more. The more rough the surfaces more friction we have.
The rougher the surfaces the greater the friction.
Soap surfaces have very little friction.
Friction does depend on the types of surfaces involved and how hard the surfaces push together. Friction would be very minimal if the surfaces were smooth and not pushing together too hard.
Yes, anything from 2 surfaces creates friction.

Faster: Surfaces with less friction (smooth) ;slanted surfaces Slower: Surfaces with more friction (sticky surfaces, rough surfaces), uphill surfaces Of course a slanted surface with too much friction will also make the car slower.
