The horizontal axis is the concentration of the ligand. As the Hill coefficient is increased, the saturation curve becomes steeper. In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect the binding of ligands to macromolecules, as a function of the ligand concentration.
Numerical modelling indicate that in periglacial settings broad low-angle convex hilltops can form in no less than millions of years. During the evolution of these slopes steeper initial slopes are calculated to result in the formation of numerous tors during the course of the lowering and broadening of the convex area.
Drumlin – Elongated hill formed by glacial action; Dry lake – Area that contained a standing surface water body; Dune – Hill of loose sand built by aeolian processes or the flow of water; Dune system – Hill of loose sand built by aeolian processes or the flow of water
Drumlin – an elongated whale-shaped hill formed by glacial action. Butte – an isolated hill with steep sides and a small flat top, formed by weathering. Kuppe – a rounded hill or low mountain, typical of Central Europe. Tor – a rock formation found on a hilltop; also used to refer to the hill, especially in South West England and the ...
This conical hill in Salar de Arizaro, Salta, Argentina called Cono de Arita constitutes a landform. A landform is a natural or anthropogenic [1] [2] land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography.
It is formed by the more erosion-resistant sandstones of the Dakota Formation protecting the softer, less erosion-resistant strata of the Morrison Formation. Hogsback up Bald Mountain, in the Adirondacks of New York. Dinosaur Ridge is a well known hogback that is part of Morrison Fossil Area National Natural Landmark within Morrison, Colorado.
In general usage, a cuesta is a hill or ridge with a gentle slope (backslope) on one side, and a steep slope (frontslope) on the other. The word is from Spanish: "flank or slope of a hill; hill, mount, sloping ground". In geology and geomorphology, cuesta refers specifically to an asymmetric ridge with a long and gentle backslope called a dip ...
A homoclinal ridge or strike ridge is a hill or ridge with a moderate, generally between 10° and 30°, sloping backslope. Its backslope is a dip slope, that conforms with the dip of a resistant stratum or strata, called caprock.
