What do fins do for a submarine?
The fins help steer the submarine; making it be able to turn left or right.
What is are the fins called on a submarine?
fairwater planes
Does a submarine need fins to move?
It doesn't need fins to move forwards, but fins are used to control rolling from side to side
How do stabilizng fins help a submarine move?
Stabilising fins prevent a side to side rolling motion.
Why does a dolphin have a fin on its back?
Fins have a stabilizing role; they help a dolphin to swim in a straight line.
Why are the fins on the submarines are used?
They are actually called "planes" on a submarine and allow it to maneuver underwater. Horizontal "planes" allow the submarine to go up/down, vertical "planes" allow the submarine to go left/right.
How submarine caused to submerge without use propulsion propeller and fins?
A submarine can submerge by filling ballast and trimmer tanks with sea water. The additional weight will take the submarine down. To resurface, the submarine will blow the sea water out of the tanks using compressed air. The air in the tanks make the submarine buoyant, so it rises and floats on the surface. Though a stationary submarine can submerge in this way, it usually submerges going forward and using diving plane (fins) to steepen the dive, so getting under the surface faster.
What do the side fins do for a fish?
They assist in stabilizing the fish so that it doesn't roll side to side. It also helps it change its depth in the water working like a wing so it can move up and down.
What happens to a submarine's movement in the absence of stabilizing fins?
Loss of the trim planes would be a pain, but wouldn't be catastrophic. Trim planes work for a submarine much the same way that the tail fins of a plane help keep it stable in flight, but for a submarine it's not as critical unless you're in a combat situation. In most situations the boat would just surface since only helm control is necessary while surfaced, unless you're in heavy seas. Trim planes (stabilizing fins) are actually a precise control surface that allows finer depth control while moving during submerged operations, but it isn't the only way a boat maintains stability. The boat's trim tanks are the primary stabilization method for leveling control, while the boat's dive planes control ascent & descent through the depths. Trim/Dive tanks also help control depth to a finer degree, helping the boat achieve a state of Neutral Buoyancy underwater, the same way a diver does. Remember also that even if main hydraulics to the trim planes was lost, they can still be operated manually, although it's not easy hand-pumping it into position. The boat would have to have sustained serious damage for such an occurrence.
When stabilizing selection acts to elimination extremes at both ends of a range of phenotypes the frequencies of the intermediate phenotypes increase?
That is the definition of stabilizing selection.
When individuals with an average form of a trait have the highest fitness?
Stabilizing selection
What is the type of natural selection that favors intermediate phenotypes?
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
