What's the difference between dichromatic and existing?
Dichromatic
Definition:
(a.) Having or exhibiting two colors.
(a.) Having two color varieties, or two phases differing in color, independently of age or sex, as in certain birds and insects.
Example Sentences:

(3) Discrimination tests reveal that these squirrels have dichromatic colour vision with spectral neutral points centered at 507.5 nm.
(4) The results indicate that dichromatic and trichromatic monkeys differ only trivially on tests where performance is based on the contributions of non-opponent mechanisms, that the contribution of spectrally opponent mechanisms to the "brightness signal" is very similar in trichromatic and dichromatic monkeys, and that in increment-threshold discriminations where there are both chromaticity and luminance cues some test wavelengths yield superior performance for trichromats while others appear to favor the dichromat.
(5) Both sets of data for the two types of dichromat satisfy linearity properties.
(6) Spectral characteristics of X-linked Dichromats (13 protanopes, 20 deuteranopes) were studied with spectral ERG.
(7) The results imply that newborns have some, albeit limited, ability to discriminate chromatic from achromatic stimuli and hence, that they are at least dichromats.
(8) Measurements were carried out using noninvasive techniques: quantitative computer tomography and dual photon absorptiometry (mono- and dichromatic).
(9) Many errors were due to the small number of protanopes averaged and inability to distinguish trichromats from dichromats.
(10) If dichromats lack one of the normal pigments then the upset of these matches monitors the change in spectral sensitivity of a single mechanism.3.
(11) Then, the chromaticity-coordinates of each color cap were calculated using the spectral distribution of standard illuminant C. The theoretical patterns of the panel D-15 test for dichromats were obtained based on the confusion lines.
(12) Two of the four observers had normal trichromatic colour vision; the other two were dichromats (protanopes).
(13) Thus the color vision in these animals is dichromatic.
(14) Spectrophotometric analysis of this blue dye at different concentrations and with or without heparin showed that the reddish hues are due to dichromatism and not metachromasia.
(15) The results suggest that the adult expression of dichromatic color vision does not depend on color experience during the first 4 months of life.
(16) Collectively, these and previous results imply that although newborns have at least dichromatic color vision, they possess relatively poor chromatic-achromatic discrimination in two spectral regions - in the short-wavelengths (including stimuli of 470-480 nm) and in the mid-wavelengths (including 565 nm).
(17) (3)-(8) are consistent and allow the calculation of a maximum optical density for those pigments which underlie the dichromats' long-wave mechanism.
(18) An intense background also changes the relative spectral sensitivity of the dichromats.
(19) Temporal properties of the short-wavelength cone mechanism of the California ground squirrel (Spermophilus beecheyi), a dichromat, were explored with single light pulses and pulse trains.
(20) Sampling was from the femoral artery through a dichromatic cuvette densitometer.
Existing
Definition:
(p. pr. & vb. n.) of Exist
Example Sentences:
(1) One hundred and twenty-seven states have said with common voice that their security is directly threatened by the 15,000 nuclear weapons that exist in the arsenals of nine countries, and they are demanding that these weapons be prohibited and abolished.
(2) The only other evidence of Kopachi's existence is the primary school near the memorial.
(3) Subsequently, the study of bundle branch block and A-V block cases revealed that no explicit correlation existed between histopathological changes and functional disturbances nor between disturbances in conduction (i.e.
(4) It has recently been suggested that procaine penicillin existed in solution in vitro and in vivo as a "procaine - penicillin" complex rather than as dissociated ions.
(5) The data suggest that major differences may exist between ruminants and non-ruminants in the response of liver metabolism both to lactation per se and to the effects of growth hormone and insulin.
(6) The obvious need for highly effective contraception in women with existing disorders of glucose metabolism has led to a search for oral contraceptive (OC) regimens for such women that are efficient but without unacceptable metabolic side effects.
(7) These results are discussed in relation to the possible existence of enzyme-bound intermediates of nitrogen fixation.
(8) Psychiatry unlike philosophy (with its problem of solipsism) recognizes the existence of other minds from the nonverbal communication between doctor and patient.
(9) Over the past decade the use of monoclonal antibodies has greatly advanced our knowledge of the biological properties and heterogeneity that exist within human tumours, and in particular in lung cancer.
(10) This suggests that a physiological mechanism exists which can increase the barrier pressure to gastrooesophageal reflux during periods of active secretion of the stomach, as occurs in digestion.
(11) After four years of existence, many evaluations were able to show the qualities of this system regarding root canal penetration, cleaning and shaping.
(12) The authors conclude that H. pylori alone causes little or no effect on an intact gastric mucosa in the rat, that either intact organisms or bacteria-free filtrates cause similar prolongation and delayed healing of pre-existing ulcers with active chronic inflammation, and that the presence of predisposing factors leading to disruption of gastric mucosal integrity may be required for the H. pylori enhancement of inflammation and tissue damage in the stomach.
(13) Elongation of existing RNA primers by the human polymerase-primase was semi-processive; following primer binding the DNA polymerase continuously incorporated 20 to 50 nucleotides, then it dissociated from the template DNA.
(14) Richard Hill, deputy chief executive at the Homes & Communities Agency , said: "As social businesses, housing associations already have a good record of re-investing their surpluses to build new homes and improve those of their existing tenants.
(15) The relative strength of the progressions varies with excitation wavelength and this, together with the absence of a common origin, indicates the existence of two independent emitting states with 0-0' levels separated by either 300 or 1000 cm-1.
(16) Participants were selected from existing classes forming a weight training, aerobic exercise and activity control group.
(17) Neurotensin (NT) is an endogenous brain tridecapeptide for which high affinity binding sites exist in the central nervous system.
(18) These results are interpreted in terms of the accessory binding site theory of Ariëns, and suggest the existence of different accessory binding sites on the Ascaris GABA receptor.
(19) Achilles tendon overuse injuries exist as a spectrum of diseases ranging from inflammation of the paratendinous tissue (paratenonitis), to structural degeneration of the tendon (tendinosis), and finally tendon rupture.
(20) Little difference exists between the proportion of programs that offer training in first-trimester techniques and the proportion that train in second-trimester techniques.
