In most shelled molluscs, the shell is large enough for all of the soft parts to be retracted inside when necessary, for protection from predation or from desiccation. However, there are many species of gastropod mollusc in which the shell is somewhat reduced or considerably reduced, such that it offers some degree of ...

In most shrines it is considered a duty of the shrine slaves to have obligatory sex with the priest and sometimes the elders. The priest's genital organs have been dedicated to the gods of the shrine, so having sex with him is considered a sacred act - in a sense, copulating with the gods. This is the origin and meanin...

c_qrf6a57lpb3d
In Ghana, human rights organizations monitoring the practice of "trokosi" claim that shrine slaves often end up with an average of four children while in servitude, many of them by the priest or elders of the shrines. Proponents of ritual servitude deny that this is a part of the practice. There seem to be wide differe...

In most silicates, silicon atom occupies the center of an idealized tetrahedron whose corners are four oxygen atoms, connected to it by single covalent bonds according to the octet rule. The oxygen atoms, which bears some negative charge, link to other cations (Mn+). This Si-O-M-O-Si linkage is strong and rigid, which ...

In most simple games, the ESSes and Nash equilibria coincide perfectly. For instance, in the prisoner's dilemma there is only one Nash equilibrium, and its strategy (Defect) is also an ESS. Some games may have Nash equilibria that are not ESSes. For example, in harm thy neighbor (whose payoff matrix is shown here) both...

c_regaajz0m1tc
However, only B is an ESS (and a strong Nash). A is not an ESS, so B can neutrally invade a population of A strategists and predominate, because B scores higher against B than A does against B. This dynamic is captured by Maynard Smith's second condition, since E(A, A) = E(B, A), but it is not the case that E(A,B) > E(...

c_fnzc2z4ubpt6
For example, in the game Harm everyone, C is an ESS because it satisfies Maynard Smith's second condition. D strategists may temporarily invade a population of C strategists by scoring equally well against C, but they pay a price when they begin to play against each other; C scores better against D than does D. So here...

Even if a game has pure strategy Nash equilibria, it might be that none of those pure strategies are ESS. Consider the Game of chicken. There are two pure strategy Nash equilibria in this game (Swerve, Stay) and (Stay, Swerve).

c_ho5vzk02aqew
However, in the absence of an uncorrelated asymmetry, neither Swerve nor Stay are ESSes. There is a third Nash equilibrium, a mixed strategy which is an ESS for this game (see Hawk-dove game and Best response for explanation). This last example points to an important difference between Nash equilibria and ESS. Nash equ...

In most simple metals, like aluminium, the screening effect strongly reduces the electric field of the ions in the solid.

In most situations it is impractical to achieve escape velocity almost instantly, because of the acceleration implied, and also because if there is an atmosphere, the hypersonic speeds involved (on Earth a speed of 11.2 km/s, or 40,320 km/h) would cause most objects to burn up due to aerodynamic heating or be torn apar...

In most situations, relativistic effects can be neglected, and Newton's laws give a sufficiently accurate description of motion.

In most situations, the user does not want to just capture an arbitrary time that an event occurs, but wants to measure a time interval, the time between a start event and a stop event.

In most snakes, teeth are located on the dentary of the lower jaw, the maxilla, the palatine bone and the lateral pterygoid plate.

In most societies, the death of one of the partners terminates the marriage, and in monogamous societies, this allows the other partner to remarry, though sometimes after a waiting or mourning period.

In most solids (but not all), the molecules have a fixed mean position and orientation, and therefore the only degrees of freedom available are the vibrations of the atoms. Thus the specific heat is proportional to the number of atoms (not molecules) per unit of mass, which is the Dulong–Petit law. Other contributions ...

Therefore, the heat capacity of a sample of a solid substance is expected to be 3RNa, or (24.94 J/K)Na, where Na is the number of moles of atoms in the sample, not molecules. Said another way, the atom-molar heat capacity of a solid substance is expected to be 3R = 24.94 J⋅K−1⋅mol−1, where "amol" denotes an amount of t...

c_xo3o49z8pazm
One way to look at this result is to observe that the monatomic gas can only store energy as kinetic energy of the atoms, whereas the solid can store it also as potential energy of the bonds strained by the vibrations. The atom-molar heat capacity of a polyatomic gas approaches that of a solid as the number n of atoms ...

A well-known ion conductive solid is β''-alumina ("BASE"), a form of aluminium oxide that has channels through which sodium cations can hop.

In most species, adult females lay their eggs in stagnant water: some lay near the water's edge while others attach their eggs to aquatic plants.

In most species, the principal eyes are more visually acute than the secondary eyes, at the cost of their sensitivity.

In most species, the stomach itself is a relatively simple sac, and is the main site of digestion.

In simple data sets, the units are in one-to-one correspondence with the data values. In more complex data sets, multiple measurements are made for each unit. For example, if blood pressure measurements are made daily for a week on each subject in a study, there would be seven data values for each statistical unit.

X is the number of faces of each dice.For example, if a game calls for a roll of d4 or 1d4, it means "roll one 4-sided die." If the final number is omitted, it is typically assumed to be a six, but in some contexts, other defaults are used. 3d6 would mean "roll three six-sided dice."

Commonly, these dice are added together, but some systems could direct the player use them in some other way, such as choosing the best die rolled.

B is a number to be added to the sum of the rolls. So, 1d20−10 would indicate a roll of a single 20-sided die with 10 being subtracted from the result. These expressions can also be chained (e.g. 2d6+1d8), though this usage is less common.
