multicellular filamentous pwm. macroscopicfilamentous kab mob uas tsim lub cev loj txiv hmab txiv ntoo. Qee lub sij hawm cov pab pawg raug hu ua ' nceb ', mas nceb tsuas yog ib feem ntawm lub kab mob peb pom saum toj no uas tseem hu ua lub cev fruiting. ib leeg xwb microscopic poov xab.
Ntawm no, puas yog nceb nceb ntau los yog unicellular?
Ntau hom poov xab yog piv txwv ntawm kab mob uas yog unicellular thaum cov hom tsim cov classic nceb cov duab (lub kaus mom zoo li lub kaus [lossis pileus] zaum saum lub qia [lossis ntau dua kom raug “kab”] yog piv txwv ntawm cov kab mob sib txawv ntawm tes.
Tsis tas li, puas yog pwm ib leeg? A pwm (US) lub pwm (UK / NZ / AU / ZA / IN / CA / IE) yog kab mob uas loj hlob nyob rau hauv daim ntawv ntawm multicellular filaments hu ua hyphae. Nyob rau hauv sib piv, fungi uas canadopt a tib leeg xwb - celled Kev loj hlob cwj pwm yog hu ua poov xab. Cov qauv tsim thiab cov duab ntawm cov spores yog ib txwm siv los faib pwm.
Ib yam li ntawd, nws tau nug, puas yog cov kab mob sib kis ntau los yog ib leeg xwb?
Kab mob ua neej nyob li os tib leeg xwb - celled kab mob los yog multicellular kab mob. Ib leeg - celled fungi raug hu ua poov xab. Thaum lub hyphae ntawm a multicellular fungi tsim ib tug complex network ntawm filaments nws yog hu ua 'mycelium'.
Hom kab mob fungi muaj dab tsi?
Kab mob yog eukaryotes thiab muaj complexcellular koom haum. Raws li eukaryotes, cov kab mob fungal muaj amembrane-bound nucleus qhov DNA tau qhwv ib puag ncig histoneproteins. Ob peb hom ntawm muaj fungi cov qauv piv rau cov kab mob plasmids (loops ntawm DNA).

Puas yog cov leeg nqaij leeg muaj ntau lub nuclei?
Lawv muaj ntau lub nuclei thiab cov nuclei no nyob ntawm ib puag ncig ntawm tes. Cov leeg pob txha tau txav mus los. Cov leeg nqaij hauv plawv tsis ntev npaum li cov leeg pob txha pob txha thiab feem ntau yog cov cell branched. Cov leeg nqaij hauv plawv tuaj yeem yog mononucleated lossis binucleated
Puas yog larvae ib leeg lossis ntau ntau?
Nws yog qhov xav paub tias daim ntawv foos raug siv tsis raug - zoo li yog ob qho tib si thiab ntau tshaj. Siv lo lus 'larva' (pl. 'Larvae'). Ntau tus kws tshawb fawb keeb kwm tsis raug siv lo lus 'larvae' ua ob qho tib si thiab ntau ntau ['a larvae', 'two larvae']
Puas yog ib leeg leeg leeg leeg DVT?
Distal DVT yog nyob ntawm tus ceg qis thiab suav nrog cov leeg infrapopliteal, xws li tom qab tibial, peroneal, sab xub ntiag tibial thiab leeg leeg leeg leeg (ib leeg lossis gemellar). Cov hlab ntshav popliteal tsis suav tias yog qhov nyob deb. Distal DVT tsis yog ib yam li proximal DVT
Lub sij hawm twg txhais tau hais tias spasm lossis twitching ntawm cov leeg nqaij lossis pab pawg ntawm cov leeg?
Mob myoclonus. spasm lossis twitching ntawm cov leeg lossis pab pawg ntawm cov leeg
Puas yog lo lus dav dav txhais tau tias yog mob ntawm daim tawv nqaij lossis pob khaus uas tuaj yeem muaj ntau yam ua rau nws yog ib qho cim ntawm ntau hom tawv nqaij tsis xws luag?
Dermatitis yog lo lus dav dav uas piav txog kev ua rau tawv nqaij. Dermatitis yog ib yam mob uas muaj ntau yam ua rau thiab tshwm sim ntau yam. Nws feem ntau yog khaus, tawv nqaij qhuav los yog pob khaus ntawm daim tawv nqaij o, reddened
