Sab hauv Micrometer: Thaum lub micrometer sab nraud yog siv los ntsuas lub cheeb sab nraud ntawm ib qho khoom, lub micrometer sab hauv yog siv los ntsuas sab hauv, lossis sab hauv txoj kab uas hla (ID)
Nws qhov chaw nyob hauv qhov chaw basalt no tau qhia rau qee tus kws tshawb fawb txog keeb kwm tias nws yog lub roob hluav taws kub. Niaj hnub no, txawm li cas los xij, Lonar Crater tau nkag siab tias yog qhov tshwm sim ntawm kev cuam tshuam meteorite uas tshwm sim ntawm 35,000 thiab 50,000 xyoo dhau los
Nws yog tsim los ntawm kwv yees li 96 subunits koom ua peb lub luag haujlwm enzymes hauv tib neeg: 20-30 daim ntawv ntawm pyruvate dehydrogenase E1 tivthaiv, 60 daim ntawv ntawm pyruvate dehydrogenase E2 tivthaiv, thiab 6 daim ntawv ntawm dihydrolipoyl dehydrogenase (E3)
Heredity yog qhov dhau los ntawm cov yam ntxwv ntawm niam txiv mus rau cov xeeb ntxwv los ntawm cov txheej txheem ntawm kev sib qhia cov ntaub ntawv caj ces qhov twg raws li kev hloov pauv yog qhov hloov pauv zuj zus hauv cov cim qub txeeg qub teg ntawm cov pej xeem lom neeg ntau tiam neeg. Qhov txawv ntawm heredity thiab evolution yog lub sij hawm bound phenomenas
Ib qho ecosystem yuav tsum muaj cov neeg tsim khoom, cov neeg siv khoom, cov decomposers, thiab cov khoom tuag thiab inorganic. Txhua lub ecosystems xav tau lub zog los ntawm lwm qhov chaw - qhov no feem ntau yog lub hnub. Cov nroj tsuag xav tau lub hnub ci rau photosynthesis thiab tsim cov piam thaj, muab lub zog rau lwm yam kab mob
Kev tawg tsis tawg yog nyiam los ntawm cov ntsiab lus roj tsawg thiab cov viscosity magmas (basaltic rau andesitic magmas). Yog tias qhov viscosity tsawg, qhov tawg tsis tawg feem ntau pib nrog cov qhov hluav taws kub vim yog tso tawm cov pa yaj. Thaum magma nce mus txog saum npoo av, nws hu ua lava
Lub Succulent Karoo biome yog qhov chaw thoob ntiaj teb lees paub biodiversity hotspot, thiab yog lub ntiaj teb tsuas yog arid hotspot. Qhov no biodiversity yog vim loj speciation ntawm ib tug arid-adapted biota nyob rau hauv teb rau tshwj xeeb climatic tej yam kev mob thiab siab heterogeneity ib puag ncig
Nyob rau hauv ferns, lub multicellular sporophyte feem ntau pom tau tias yog ib tsob nroj fern. Hauv qab ntawm fronds yog sporangia. Nyob rau hauv lub sporangia yog spores tsim cov hlwb hu ua sporogenous hlwb. Cov hlwb no tau txais meiosis los tsim cov kab mob haploid
Tus nqi ntsuas t ntsuas los ntsuas seb cov txhais tau txawv li cas tuaj yeem suav tau raws li hauv qab no: t = mA − mB √ S2nA + S2nB. S2 yog qhov kwv yees ntawm qhov sib txawv ntawm ob qho piv txwv. Nws tuaj yeem suav tau raws li hauv qab no: S2 = ∑ (x − mA) 2 + sum; (x − mB) 2nA + nB − 2
Thaum cov phiaj xwm dej hiav txwv los yog cov teb chaws sib tw dhau los ntawm ib qho kev taw qhia, lossis txav mus rau tib qho kev taw qhia tab sis ntawm qhov sib txawv, qhov kev hloov pauv ntawm thaj tsam raug tsim. Tsis muaj cov crust tshiab tsim los yog subducted, thiab tsis muaj volcanoes tsim, tab sis av qeeg tshwm sim raws qhov txhaum
Cog. Conifers tuaj yeem cog rau lub caij nplooj ntoo hlav thaum ntxov (Lub Peb Hlis txog Lub Tsib Hlis) thiab lub caij nplooj zeeg thaum ntxov (Lub Cuaj Hli txog Lub Kaum Hli). Raws li nrog rau tag nrho cov nroj tsuag, sim cog koj cov conifers nyob rau hauv ib tug overcast hnub thaum tsob ntoo yuav poob dej tsawg los ntawm transpiration (cov evaporation ntawm cov dej los ntawm cov nroj tsuag)
Yog li thaum cov kws tshaj lij xa cov pob ntawm 30 meters ib ob thiab 1,200 phaus ntawm lub zog, tus neeg laus nruab nrab xa pob ntawm ib ncig ntawm 25 meters ib ob raws li kev ncaws pob ntawm 1,000 phaus ntawm lub zog, thaum cov tub ntxhais hluas nruab nrab tsuas tuaj yeem sau lub pob. ceev ntawm 14.9 meters ib ob, qhia tsuas yog 600 phaus

Jellyfish thiab hiav txwv anemones yog ib co tsiaj nrog lub cev lub hom phiaj. Thiab tam sim no qhov koj tau tos rau: biradial symmetry, uas yog thaum lub cev tuaj yeem muab faib ua qhov sib npaug, tab sis tsuas yog nrog ob lub dav hlau. Nws txawv ntawm radial symmetry, vim hais tias ob lub dav hlau faib lub cev, tab sis tsis ntau tshaj ob
Quadrant IV, nyob rau sab xis ntawm daim duab, tsuas muaj cov ntsiab lus uas nyob rau sab xis ntawm xoom ntawm x-axis thiab qis dua xoom ntawm y-axis; yog li ntawd, tag nrho cov ntsiab lus nyob rau hauv lub quadrant no yuav muaj ib tug zoo x tus nqi thiab ib tug tsis zoo yvalue
Kev hloov ntsug yog thaum daim duab qhia txav mus rau vertically, nce lossis nqis. Qhov kev txav yog txhua yam raws li qhov tshwm sim rau y-tus nqi ntawm daim duab. Lub y-axis ntawm lub dav hlau ua haujlwm yog qhov ntsug. Thaum muaj nuj nqi hloov vertically, y-tus nqi hloov
Lub scatterplot yog siv los sawv cev rau kev sib raug zoo ntawm ob qhov sib txawv. Muaj ob hom kev sib raug zoo: zoo thiab tsis zoo. Cov kev hloov pauv uas muaj kev cuam tshuam zoo txav mus rau tib qho kev taw qhia, thaum cov hloov pauv uas tsis zoo cuam tshuam txav mus rau qhov sib txawv
Lub npe: xenon-135, Xe-135
Parallels yog lwm lub npe rau kab ntawm latitude. Koj yuav pom tias cov kab no tsis sib sau ua ke, lossis tuaj ua ke, nyob qhov twg hauv ntiaj teb. Peb hu cov kev sib piv no vim lawv ib txwm muaj qhov sib npaug sib nrug. Thawj qhov sib luag yog kab zauv
Prokaryote Txhais. Prokaryotes yog cov kab mob unicellular uas muaj tib lub cell prokaryotic. Cov kab mob thiab Archaea yog ob hom ntawm lub neej uas yog prokaryotes. Prokaryotes tuaj yeem sib piv nrog eukaryotes, uas muaj ntau lub hlwb eukaryotic nrog cov nucleus thiab organelles
Lub perpendicular kab yog ib txoj kab uas hla lwm txoj kab ntawm lub kaum sab xis 90 °. Txhua lub ces kaum sib ntsib ntawm lub kaum sab xis 90 °. Qhov no tseem hu ua lub kaum sab xis. Peb tuaj yeem pom cov kaum sab xis nyob rau hauv cov ces kaum ntawm cov squares thiab tej zaum hauv daim duab peb sab
