Nquag, a tus neeg tau txais ob daim ntawv theej ntawm cov noob uas tsim cov beta-globin, cov protein uas xav tau los tsim cov hemoglobin ib txwm muaj (hemoglobin A, genotype UA). A tus neeg uas muaj mob qog noj ntshav inherits ib txwm allele thiab ib qho txawv txav allele encoding hemoglobin S (hemoglobin) genotype AS).
Ua raws li qhov no hauv kev xav, dab tsi yog qhov phenotype thiab genotype ntawm sickle cell anemia?
Ib qho kev sib xyaw ntawm ob qho ntawm cov alleles sawv cev rau tus neeg genotype . Cov neeg nrog genotype AS muaj cov Sickle cell trait phenotype , thiab cov tib neeg nrog SS genotype muaj cov kab mob kis kab mob phenotype.
Tom qab ntawd, lo lus nug yog, yog vim li cas cov neeg mob ntshav qab zib mob malaria tiv taus? Cov neeg txhim kho kab mob - cell kab mob, ib yam mob uas tus ntshav liab hlwb yog txawv txav, yog tias lawv txais tau ob faulty luam ntawm tus gene rau tus oxygen nqa protein hemoglobin. Lawv cov txiaj ntsig qhia tau tias tus noob tsis tiv thaiv kab mob los ntawm tus mob malaria parasite, raws li yav tas los xav.
Dhau li ntawm no, dab tsi yog cov cim qhia ntawm AS genotype?
- qaug zog heev los yog chim siab, los ntawm anemia.
- fussiness, nyob rau hauv cov me nyuam.
- bedwetting, los ntawm cov teeb meem rau lub raum.
- jaundice, uas yog yellowing ntawm lub qhov muag thiab tawv nqaij.
- o thiab mob ntawm tes thiab ko taw.
- nquag kis kab mob.
- mob hauv siab, nraub qaum, caj npab, lossis ceg.
Tus kab mob kis kab mob yog dab tsi?
Sickle cell zoo (tseem hu ua a tus cab kuj ) tshwm sim thaum ib tug neeg muaj ib lub noob rau kab mob hemoglobin thiab ib lub noob rau ib txwm hemoglobin. Kwv yees li ib ntawm kaum African-Asmeskas nqa kab mob cell zoo . Cov neeg uas yog cov cab kuj feem ntau tsis muaj teeb meem kho mob thiab ua rau lub neej zoo.

Dab tsi yog qhov tseem ceeb ntawm cov kab mob hauv cov ntshav?
Ntshav. Tib neeg cov ntshav muaj cov tsis muaj carbonic acid (H 2CO 3) thiab bicarbonate anion (HCO 3 -) txhawm rau tswj cov ntshav pH ntawm 7.35 thiab 7.45, raws li tus nqi siab dua 7.8 lossis qis dua 6.8 tuaj yeem ua rau tuag taus
Cov khoom qab zib uas tsis yog crystalline yog dab tsi?
Cov khoom qab zib noncrystalline, xws li cov khoom qab zib nyuaj, caramel, toffees, thiab nougats, yog chewy los yog tawv, nrog cov qauv homogeneous. Crystalline candies, xws li fondant thiab fudge, yog du, creamy, thiab chewed yooj yim, nrog ib tug meej qauv ntawm cov muaju me me
Tus kab mob puas yog kab mob multicellular?
Cov kab mob tsis raug cais raws li cov hlwb thiab yog li ntawd tsis muaj unicellular los yog multicellular kab mob.Viruses muaj genomes uas muaj xws li DNA los yog RNA, thiab muaj cov piv txwv ntawm cov kab mob uas yog ob leeg-stranded los yog ib leeg-stranded
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
