Keeb kwm kev loj hlob
Catholic pov thawj Nicholas Steno tsim lub hauv paus theoretical rau stratigraphy Thaum nws qhia txog txoj cai ntawm superposition, lub hauv paus ntsiab lus ntawm thawj kab rov tav thiab lub hauv paus ntsiab lus ntawm lateral continuity nyob rau hauv 1669 ua hauj lwm nyob rau hauv lub fossilization ntawm cov organic tseem nyob rau hauv cov txheej ntawm sediment.
Ib sab ntawm no, leej twg yog leej txiv ntawm stratigraphy?
William Smith
Qhov thib ob, stratigraphy txhais li cas hauv keeb kwm? Stratigraphy , scientific kev qhuab qhia txog kev piav qhia ntawm pob zeb successions thiab lawv txhais nyob rau hauv cov nqe lus ntawm ib tug dav lub sij hawm teev. Nws muab lub hauv paus rau keeb kwm geology, thiab nws cov hauv paus ntsiab lus thiab cov txheej txheem tau pom daim ntawv thov hauv thaj chaw xws li roj av geology thiab archaeology.
Ib yam li ntawd ib tug yuav nug, leej twg tsim lub tswv yim ntawm stratigraphy quizlet?
Tsim los ntawm William Smith.
Yuav ua li cas archaeologists siv stratigraphy?
Stratigraphy yog qhov tshwm sim ntawm dab tsi geologists thiab archaeologists xa mus rau raws li "txheej txheem ntawm stratification", los yog txheej txheem los ntawm cov txheej txheem ntawm cov av thiab cov khib nyiab tau muab tso rau saum ib leeg dhau sijhawm. Qhov no ua haujlwm tib yam rau archaeology , thiab tuaj yeem siv los txiav txim ib ntu ntawm cov xwm txheej.

Leej twg tau txais txiaj ntsig los ntawm kev tshawb pom lub hauv paus rau kev tsim noob neej?
Thaum Gregor Mendel pib kawm txog kev xeeb tub hauv xyoo 1843, chromosomes tseem tsis tau pom nyob hauv lub tshuab tsom. Tsuas yog nrog cov koob tshuaj zoo dua thiab cov tswv yim zoo thaum lub sijhawm xyoo 1800s tuaj yeem ua rau cov kws tshawb fawb ntawm tes pib stains thiab saib xyuas cov txheej txheem subcellular, pom lawv tau ua dab tsi thaum lub sijhawm cell faib (mitosis thiab meiosis)
Leej twg ntawm cov hauv qab no yog suav tias yog leej txiv ntawm kev ua haujlwm tshuaj?
Bernardino Ramazzini
Lub tswvyim thiab lub tswvyim yog dab tsi?
Raws li kev txheeb cais, lub ntsiab lus piav qhia txog kev sib raug zoo ntawm cov kev hloov pauv tshwj xeeb uas tau txheeb xyuas hauv txoj kev tshawb fawb. Nws tseem qhia txog cov tswv yim, txheej txheem thiab cov khoom tsim tawm ntawm tag nrho cov kev tshawb nrhiav. Lub tswvyim ntawm lub tswvyim tseem hu ua kev tshawb fawb paradigm
Leej twg tsim thawj daim ntawv qhia ntawm lub ntiaj teb no?
Anaximander
Leej twg yog leej niam leej txiv pab txhawb cytoplasmic qub txeeg qub teg?
Nyob rau hauv cov ntaub ntawv ntawm cytoplasmic qub txeeg qub tes, cov teebmeem ntawm niam txiv. Qhov no feem ntau yog vim muaj kev koom tes ntau dua ntawm cytoplasm rau zygote los ntawm niam txiv poj niam dua li txiv neej niam txiv. Feem ntau ovum txhawb ntau cytoplasm rau zygote dua cov phev
