What is a double walled structure containing the cells genetic code?
The cell membrane is a double-walled structure containing a cell's genetic code.
What are double or triple lid respectively double or triple walled caskets?
Luxury caskets often have a double lid, sometimes even a triple lid (the innermost being made of glass). In rare cases, caskets are even double walled (triple walled would be absolutely unusual), which means that the outer casket contains a complete inner casket, which can be taken out. Double walled caskets are much more heavy than double lid caskets, of course.
What is construction and working of thermos flask?
it consists a double walled glass vessel having a vaccum between the walls.both these walls are silvered on the vaccum side.no heat can enter or leave the inner flask by convection oor conduction across vaccum.a small amount of heat can be gained by the flask through by radiation but the silver surface to control radiant heat and reduce it to a minimum
How much pressure can a full soda can withstand?
Conducted a lab at school measuring the strain on a soda can when it was opened. Back solving for the force as if the can were a thin walled pressure vessel led us to P = -54.447 +- 0.047288 Psi to 95% confidence.
How do you find the operating pressure of a hydraulic cylinder?
this is question related to the strength of materials rather than the hydraulics the basic equation for the stresses in thick walled cylinders will give you the pressure at which the respective hydraulic cylinder can be operated. for radial stress=((piri2 )/ (r02 -ri2)) * ((1 - (ro2/r2))) where pi is the internal pressure of the cylinder ri is the internal radius of the cylinder. r0 is external radius of the cylinder. r is the radius of the point you have selected on the cylinder (this is mostly ri because it is the point were high stress is felt .apparently this formula gives the value of radial stress at point selected by you that is the 'r' value) for tangential stress=((piri2 )/ (r02 -ri2)) * ((1 + (ro2/r2))) adding the 'tangential stress' and the 'radial stress' would give you the value of the 'axial stress' this along with some 'factor of safety' value can determine the operating pressure of the hydraulic cylinder or in this case the internal pressure of the cylinder.
Air conditioned building have double walled window?
Because single pane glass is a lousy insulator. The layer of air between the two panes works as an insulator. This improves energy efficiency
What is a double walled structure containing the cells genetic code?
The cell membrane is a double-walled structure containing a cell's genetic code.
What is a double-walled container?
A cell that is double walled is a plant cell. This is because the plant cells can't move so they need extra protection.

What term is a double-walled membrane that encloses the heart?
Pericardium
Double walled windows are provided for houses in cold countries?
In cold countries, the windows in a room are provided with two glass panes with a layer of air in between. Since air is a poor conductor of heat, it checks the conduction of heat from the room to the outside in winter or the conduction from outside to the room in summer.e.g.The windows of air-conditioned railway coaches also have double glass panes with a layer of air in between the two panes to prevent conduction of heat through the window from either side, i.e., compartment to outside or outside to compartment.The layer of air insulates and reduces heat passage through the layers of glass. Dual pane windows also deaden sounds more effectively.
What is the double-walled membrane that produce watery fluids?
Serous membrane
Is there a phospholipid bilayer membrane surrounding the nucleus?
A double phospholipid bilayer surrounds the nucleus.
What is a double walled with molecules that have hydrophobic tails and hydrophilic head?
Phospholipid Bilayer
What is the double walled membrane that contains the blastocyst called?
Amniotic sac
What is the walled section of peking that contained the royal palaces of the emperor of the Ming dynasty?
The walled section of Peking that contained the royal palaces of the emperor of the Ming dynasty was called the Forbidden City. The Forbidden City contains over 950 buildings.
What is the name of an organelle that is a double walled vessel with the inner wall having folds known as cristae?
mitochondrion
