Phenotype txhais tau tias yog ib yam kabmob uas qhia txog lub cev zoo. Phenotype yog txiav txim siab los ntawm ib tug neeg tus genotype thiab qhia cov noob, random genetic variation, thiab ib puag ncig influences. Piv txwv ntawm lub cev phenotype suav nrog cov yam ntxwv xws li xim, qhov siab, qhov loj, qhov zoo, thiab tus cwj pwm.
Tsuas yog li ntawd, ib qho piv txwv ntawm phenotype yog dab tsi?
A phenotype yog ib qho zoo uas peb tuaj yeem soj ntsuam. Cov noob muaj cov lus qhia, thiab qhov tshwm sim ntawm peb lub cev ua raws li cov lus qhia no (rau piv txwv , ua pigment nyob rau hauv peb ob lub qhov muag), yog a phenotype qhov zoo, zoo li qhov muag xim. Qee lub sij hawm qhov zoo yog qhov tshwm sim ntawm ntau cov noob sib txawv, zoo li 16 cov noob muaj lub luag haujlwm rau qhov muag xim.
Tsis tas li ntawd, yuav ua li cas genotype ua phenotype? Genotype & Phenotype . Lus txhais: phenotype yog lub constellation ntawm observable zoo; genotype yog lub txiaj ntsim ntawm noob neej. Phenotype = genotype + kev loj hlob (hauv ib puag ncig muab). Nyob rau hauv lub nqaim "genetic" kev nkag siab, lub genotype txhais cov phenotype.
Raws li txoj cai, koj ua li cas txiav txim siab txog genotype thiab phenotype?
Cov txiaj ntsig ntawm lub cev cov yam ntxwv pom tau yog lawv phenotype . Qhov sib txawv tseem ceeb ntawm phenotype thiab genotype yog li ntawd, thaum genotype yog tau txais los ntawm lub cev niam txiv, lub phenotype tsis yog. Hos a phenotype yog influenced genotype , genotype tsis sib npaug phenotype.
Puas yog qhov muag xim yog phenotype?
Qhov pom qhov muag xim yog koj phenotype , tab sis nws tsis qhia peb tsis muaj dab tsi txog koj genotype. Ntau yam noob caj noob ces cuam tshuam qhov muag xim hauv tib neeg, thiab ib qho ntawm lawv tuaj yeem pom qhov tseem ceeb lossis qhov tsis zoo hauv koj phenotype - uas yog, qhov tshwj xeeb ntxoov ntxoo ntawm xim av hauv koj qhov muag.

Yuav ua li cas txiav txim seb tus naj npawb ntawm phenotypes ib tug muab zoo?
Yuav ua li cas txiav txim seb tus naj npawb ntawm phenotypes rau ib tug muab? Tus naj npawb ntawm cov noob uas tswj tau qhov zoo. Cov yam ntxwv tswj los ntawm ob lossis ntau lub noob. Muaj ntau hom genotypes thiab ntau phenotypes vim tias muaj ob lossis ntau dua alleles
Dab tsi txiav txim siab qhov siab ntawm txhua lub ncov hauv photoelectron spectrum?
Yuav ua li cas txiav txim siab txoj hauj lwm thiab qhov siab (kev siv) ntawm txhua lub ncov hauv photoelectron spectrum? Txoj hauj lwm ntawm txhua lub ncov yog txheeb xyuas los ntawm lub zog ionization, qhov siab ntawm txhua lub ncov qhia qhov sib piv ntawm cov hluav taws xob hauv txhua qib lossis orbital
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Lub siab coefficient ntawm kev txiav txim siab txhais li cas?
Lub ntsiab lus ntawm Coefficient ntawm Kev Txiav Txim Nws muab koj lub tswv yim ntawm pes tsawg cov ntaub ntawv cov ntsiab lus poob rau hauv cov txiaj ntsig ntawm kab tsim los ntawm kev sib npaug regression. Qhov siab dua qhov coefficient, qhov feem pua ntawm cov ntsiab lus ntau dua cov kab dhau los thaum cov ntaub ntawv cov ntsiab lus thiab kab tau npaj
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
