What's the difference between dichromatic and occurring?
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:

(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.

(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.
Occurring
Definition:
(p. pr. & vb. n.) of Occur
Example Sentences:
(1) Once treatment began, no significant changes occurred in Group 1, but both PRA and A2 rose significantly in Groups 2 and 3.
(2) Direct fetal digitalization led to a reduction in umbilical artery resistance, a decline in the abdominal circumference from 20.3 to 17.8 cm, and resolution of the ascites within 72 h. Despite this dramatic response to therapy, fetal death occurred on day 5 of treatment.
(3) Patients with papillary carcinoma with a good cell-mediated immune response occurred with much lower infiltration of the tumor boundary with lymphocyte whereas the follicular carcinoma less cell-mediated immunity was associated with dense lymphocytic infiltration, suggesting the biological relevance of lymphocytic infiltration may be different for the two histologic variants.
(4) It is concluded that during exposure to simulated microgravity early signs of osteoporosis occur in the tibial spongiosa and that changes in the spongy matter of tubular bones and vertebrae are similar and systemic.
(5) HSV I infection of the hand classically occurs in children with herpetic stomatitis and in health care workers infected during patient care delivery.
(6) Such an increase in antibody binding occurred simultaneously with an increase in the fluidity of surface lipid regions, as monitored by fluorescence depolarization of 1-(trimethylammoniophenyl)-6-phenyl-1,3,5-hexatriene.
(7) As far as acrophase table is concerned for all enzymes and fractions the acrophase occurred during the night.
(8) Electronmicroscopical investigations have revealed that, under normal conditions, a minor vesicular transfer of intravenously injected peroxidase occurs across the endothelium in segments of arterioles, capillaries and venules, especially in arterioles with a diameter about 15-30 mu.
(9) No significant change occurred in the bacterial population of our hospital unit during the period of the study (more than 3 years).
(10) The highest rate of discontinuation occurred when method choice was denied in the presence of husband-wife agreement on method choice, and the lowest rate occurred when method choice was granted in the presence of such concurrence.
(11) The secondary leukemia that occurred in these patients could be distinguished from the secondary leukemia that occurs after treatment with alkylating agents by the following: a shorter latency period; a predominance of monocytic or myelomonocytic features; and frequent cytogenetic abnormalities involving 11q23.
(12) An inflammatory process than occurs in the airways that is characterized by an influx of eosinophils and neutrophils into the airway epithelium and bronchial fluids.
(13) A clinical and microbiologic response occurred when anticoagulation therapy with heparin was added to the treatment regimen.
(14) Infection with opportunistic organisms, either singly or in combination, is known to occur in immunocompromised patients.
(15) A commensurate rise in both smoking and adenocarcinoma has occurred in the Far East where the incidence rate (40%) is twice that of North America or Europe.
(16) As prolongation of the action potential by TEA facilitates preferentially the hormone release evoked by low (ineffective) frequencies, it is suggested that a frequency-dependent broadening of action potentials which reportedly occurs on neurosecretory neurones may play an important role in the frequency-dependent facilitation of hormone release from the rat neurohypophysis.
