Xav txog qhov no, dab tsi yog tas2r38 gene?
Wikidata. Saib/Edit Human. Saib/ kho nas. Saj receptor 2 tus tswv cuab 38 yog cov protein uas nyob rau hauv tib neeg yog encoded los ntawm cov TAS 2R38 gene . TAS 2R38 yog iab saj receptor; sib txawv genotypes ntawm TAS 2R38 cuam tshuam lub peev xwm saj ob qho tib si 6-n-propylthiouracil (PROP) thiab phenylthiocarbamide (PTC).
Ib yam li ntawd, cov alleles rau PTC noob yog dab tsi? PTC - saj peev xwm yog ib qho yooj yim caj ces kev cai tswj hwm los ntawm ib khub ntawm alleles , dominant T rau saj thiab recessive t rau nontasting.
Ib sab saum toj no, dab tsi yog super taster noob?
Supertasters yug los nrog lub peev xwm no. Cov kws tshawb fawb ntseeg feem ntau supertasters muaj cov noob TAS2R38, uas ua rau kom iab kev xav. Cov noob ua supertasters rhiab heev rau iab tsw hauv txhua yam khoom noj thiab dej haus. Cov neeg nrog qhov no noob tshwj xeeb tshaj yog rau cov tshuaj hu ua 6-n-propylthiouracil (PROP).
Puas muaj peev xwm hais tias ib tug neeg uas muaj ib tug taster genotype tsis muaj peev xwm saj PTC Vim li cas los yog vim li cas tsis?
Zoo li txhua yam tsis yog- cov saj (dd) tsis tuaj yeem saj PTC , hos homozygous cov saj (TT) qee zaus qhia ib qho tsis muaj peev xwm los yog tsis muaj peev xwm mus saj cov tshuaj. Lub heterozygous genotype (Tt) muaj qhov "leakiest" phenotype raws li txo lossis tsis tuaj saj muaj peev xwm kuj muaj ntau. Qhov no yog hu ua cov nyhuv heterozygous.

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua

Tus naj npawb ntawm lub sij hawm ib qho tseem ceeb tshwm sim nyob rau hauv daim ntawv factored ntawm qhov sib npaug ntawm ib tug polynomial yog hu ua multiplicity. Qhov xoom cuam tshuam nrog qhov xwm txheej no, x = 2, muaj ntau qhov sib npaug 2 vim tias qhov xwm txheej (x− 2) tshwm sim ob zaug. X-intercept x=− 1 yog qhov rov qab daws ntawm qhov xwm txheej (x + 1) 3 = 0 (x + 1) 3 = 0

Dab tsi yog qhov index fossil Dab tsi yog ob qhov yuav tsum tau ua ib qho index fossil?
Cov pob txha muaj txiaj ntsig zoo yuav tsum yog qhov sib txawv lossis pom tau yooj yim, muaj ntau, thiab muaj qhov dav ntawm thaj chaw faib khoom thiab muaj ntau yam luv luv los ntawm lub sijhawm. Index fossils yog lub hauv paus rau kev txhais cov ciam teb nyob rau hauv lub sij hawm geology thiab rau kev sib raug zoo ntawm strata
