A circuit must be closed in order for a current to flow because it helps keep a current flow pass. When the switch is closed on a circuit there is a constant flow. When the switches open the flow is disturbed around the circuit.
1. Monocots have one cotyledon in the embryo and dicots have two 2. Vascular bundles in monocots are closed in dicots these are open 3. Leaves have parallel venation in monocots & reticulate in dicots 4. Floral parts are in multiple of three in monocots, and five or their multiple in dicots.
what does closed switch mean
A closed circuit.
arterioles are door between heart &tissue this door must be closed most of times &it just open in need so our CNS & smooth muscle of arterioles work to keep this door closed by basal vascular tone & vasomotor tone
Closed. It also has a water-vascular system. :)
Vascular bundles may be radial or conjoint depending on the position of xylem and phloem. They may be open or closed depending on the presence or absence of cambium between their xylem and phloem. They may be scattered or arranged in a ring.
Indifference curve is a set of all the consumption bundles which are indifferent in the level of utility each bundle provide. Any bundle which provide higher utility will form another IC. Thus Indifference curve is a closed set.
It depends on the type of case, how it was closed, when it was closed, and if you have a good reason to reopen.
Magnetic fields do, because there's no such thing as an isolated magnetic "pole", and a magnetic line always starts and ends at opposite poles of the same magnetized object. But electric fields don't. You can easily have a bundle of isolated positive charge over here and a bundle of isolated negative charge over there, whereupon the lines of the electric field start on one bundle and end on the other bundle. But electric field lines can also exist in closed loops, and they do that in radio waves, where the electromagnetic field propagates with an electric field component and a magnetic field component, and they both form closed loops.
All respiratory systems are open as the function of a respiratory system is to exchange gases with inside of the body and the external world. The term 'open' or 'closed' refers to the vascular system.
The only reason why any ride at Disneyland would be closed is technical difficulties
One reason was that congress outlawed the closed shop
You can say, "The office will be closed." Alternatively, you might say, "Our office will not be open." If you want to specify a reason or date, you could add, "The office will be closed for the holiday" or "The office will be closed on Friday."
The only reason a ride at Disneyland would be closed is due to technical difficulties or remodeling.
Unicellulars don't have any vascular system they take food by diffusion. Small animals such as some invertebrates have open circulatory system, larger animals like vertebrate have a closed circulatory system.
The collateral open vascular bundles of dicots display xylem and phloem that are separated from each other by the fascicular cambium. These vascular bundles are also often surrounded by abundle sheath and the whole structure is imbedded in a parenchyma tissue called pith. Another type of vascular bundles are the bicollateral bundles.
