Stabilizing selection is where a population is favored by just the right amount of a certain trait, and if they don't have the right amount of that certain trait then they die.
Example: Human babies and birth weight, if the baby is too small, i gets sick. If the baby is too big, it cannot get through the pelvis; but just the right weight and it will come out lively and well.
Disruptive selection is when an animal has to fit in with its environment; I.E., camouflage.
In population genetics, directional selection is a mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. With stabilizing selection genetic diversity decreases as the population stabilizes on a particular trait value. Diversifying selection describes changes in population genetics in which extreme values for a trait are favored over intermediate values.
I'm not sure what "stabilizing directional" selection is, but if you get out a bell curve graph...
Stabilizing selection tends to select for individuals around the average, or mean, of a population, which technically makes the curve steeper. Directional selection shifts the average in one direction (shifts the whole curve in one direction). Disruptive selection creates two new averages, which means it splits the one curve into two, smaller, separate curves.
The difference is that high contrast has more black and low contrast has more white.
Yes, barium is a contrast medium and is actually one of the most common of the contrast mediums used in enemas and other x-ray based tests. Iodine is another contrast medium that is quite common.
Contrast in any difference, but in drawing it usually refers to difference in colouring (ie-a white flower on a black background provides high contrast).
Adjustment of the mirror will change the contrast slightly.
hot and VERY humid-well,usually
A non-directional hypothesis only proposes a relationship. In contrast, a directional hypothesis also proposes a direction in the relationship. For example, when one variable increases, the other will decrease.

Natural selection is when contemporary species rose from ancestors that survived due to their physical characteristics in their habitats. A well-known example is the Galapagos Islands and how the animals on the islands adapted to their environments. Darwin convinced the biology world that diversity in organisms came from evolution (descent without modification). Artificial selection is when humans intentionally breed animals for certain traits. Unlike natural selection, where only the fittest survive, artificial selection is for human's likings. Many crops that are grown are part of artificial selection.
A Conometer is a simple device for measuring the variation of luminance of an electronic display (e.g. LCD screen) with viewing direction within a certain viewing cone. From two directional distributions of luminance (e.g. black, white) the corresponding contrast can be evaluated.
Natural selection is the most powerful driver of evolution and it is the only mechanism of evolution ( genetic drift and gene flow are two other mechanisms ) that leads to adaptive change. Natural selection is the nonrandom survival and reproductive success of of randomly varying organisms. Evolution is the change in allele frequency over time in a population of organisms.
Normally it is "in contrast with..." But "to" is used when the difference is being emphasized.
The only difference is that an if statement will be evaluated at most one time and a while statement will be evaluated repeatedly until the loop condition evaluates to false.
There is no modern contrast or indeed any ancient contrast.
The word 'contrast' is a noun (contrast, contrasts) and a verb (contrast, contrasts, contrasting, contrasted). Examples:noun: The contrast in their personalities makes them seem like a very odd couple.verb: We need to choose accessories to contrast with the outfit.
its something when a mommy contrast generalist does bonding with the daddy contrast generalist and they then form a baby contrast generalist and so forth =D
Deep is the directional term that means "within the body" and further away from the body surface. [Contrast this with superficial which means "toward the body surface".] For example: the muscular layer is deep to the skin, but superficial to the intestines.
Perception : It is the process of acquiring,interpreting,selecting, and organizing sensory info. Selection : Perception begin with selection,mind and body combine to control for selecting any particular stimuli are selected.(It's is part of Perception Process) Halo Effect : It's can be said as drawing the general impression towards someone on the basis of single activity or characteristic Contrast Effect : Evaluation of a person's characteristics that are affected by comparison's with other people recently encountered who rank higher or lower on the same characteristics.
