yog tias biomolecule yog (biochemistry) molecules, xws li amino acids, qab zib, nucleic acids, proteins, polysaccharides, dna, thiab rna, uas tshwm sim ib txwm nyob rau hauv cov kab mob nyob rau hauv thaum ntxov ua sawv. macromolecule yog (chemistry | biochemistry) ib tug loj heev molecule, tshwj xeeb tshaj yog siv nyob rau hauv reference rau loj lom polymers (xws li nucleic.
Tsis tas li ntawd, vim li cas lawv thiaj hu ua macromolecules?
Macromolecules yog loj, complex molecules. Lawv Feem ntau yog cov khoom ntawm cov khoom me me, xws li cov proteins, lipids, thiab carbohydrates. Lwm lub npe rau a macromolecule yog ib tug polymer, uas muab los ntawm Greek prefix poly- txhais tau tias "ntau units."
Qhov thib ob, dab tsi yog 4 loj macromolecules thiab lawv cov subunits? Raws li peb tau kawm, muaj plaub chav kawm loj ntawm biological macromolecules:
- Proteins (polymer ntawm amino acids)
- Carbohydrates (polymers ntawm qab zib)
- Lipids (polymers ntawm lipid monomers)
- Nucleic acids (DNA thiab RNA; polymers ntawm nucleotides)
Tom qab, lo lus nug yog, dab tsi yog 4 hom macromolecules thiab lawv txoj haujlwm?
Muaj plaub chav kawm loj ntawm biological macromolecules ( carbohydrates lipids, cov proteins , thiab nucleic acids ); txhua tus yog ib qho tseem ceeb ntawm tes thiab ua haujlwm ntau yam. Ua ke, cov molecules no ua rau feem ntau ntawm cov cell qhuav qhuav (nco ntsoov tias cov dej ua rau feem ntau ntawm nws cov khoom tiav).
Lub luag haujlwm ntawm macromolecules yog dab tsi?
Cov rog thiab roj feem ntau yog tsim los ntawm fatty acids thiab glycerol. Proteins yog ib chav kawm ntawm cov macromolecules uas tuaj yeem ua tau ntau yam kev ua haujlwm rau lub cell. Lawv pab nyob rau hauv cov metabolism los ntawm kev muab cov qauv kev txhawb nqa thiab los ntawm kev ua raws li enzymes, cov cab kuj los yog cov tshuaj hormones. Lub tsev blocks ntawm cov proteins yog cov amino acids.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
