negative pressure is needed for a sustained flow of water in a pipe.
The population needs to be small is the necessary condition for genetic drift to have a significant effect on populations.
The water will flow out of the cell.
to prevent the air from the atmosphere flow into potometer
Antidiuretic hormone works against urine flow; if it's not produced, there is excess dilute urine produced.
SBFD causes vasoconstriction, a condition in which the veins constrict and become noticable smaller.
negative pressure is needed for a sustained flow of water in a pipe.
For example, you can make an analogy with the flow of water in a tube.
A difference in temperature
A difference in charge
Negative pressure
The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
"A flow meter is necessary when dealing with air conditioners, hot water heaters, and any other types of equipment requiring the monitoring of a water or gas flow."
No. Heart murmurs are usually caused by turbulent blood flow around leaky or otherwise insufficient heart valves. Sustained ventricular systole is not a real condition as far as I know.
There is geological evidence that Mars may have had bodies of water. There are parts of the planet that seem like they had water flowing on it, or were eroded by water flow.
A device to get a current flow through a wire (i.e. from a battery) and no breaks in the wire.
The population needs to be small is the necessary condition for genetic drift to have a significant effect on populations.
it forces the water to flow in the desired direction
