Maabara mtandaoni yanawapa wanafunzi wako uwezekano wa kuendesha majaribio ya kisayansi katika mazingira ya mtandaoni. Maabara yanayoendeshwa kwa mbali (maabara ya mbali) yanakupa fursa ya kujaribu mitambo halisi kutoka sehemu za mbali. Maabara ya mtandaoni yanapatia uhai mtambo ya kisayansi. Mipangilio ya data inawasilisha data kutoka katika majaribio ya maabara yaliyofanywa awali. Tafadhali tumia vichujio kwenye upande wa kulia ili kupata maabara mtandaoni yanayofaa darasa lako. Maabara yanaweza kuunganishwa kwa Programu tumizi maalum ili kuunda Nafasi za Kusoma za Kiulizio(ILSs).

Ikiwa unatafuta maabara ya mtandaoni hasa yanafaa kwa somo la Benin, Kenya au Nigeria, tafadhali tembelea ukurasa wetu wa Makusanyo.

Mtindo huu ni masimulizi ya kulingana na wakala watu genetics. Programu ina zana kufanya majaribio virtual kukiuka dhana ya nadharia ya Hardy-Weinberg (idadi ndogo, uteuzi, walivyoelezea, uhamiaji na yasiyo ya nasibu kujaminiana).

Mtindo huu simulates ya Endler 1980 classic majaribio juu ya usawa wa kijinsia uteuzi na uchaguzi wa asili. Katika guppies, wanawake wanapendelea tendo la ndoa na wanaume ambao wana kura ya matangazo, lakini wanaume wale wanaonekana kwa urahisi zaidi kwa mahasimu.

Kuchunguza jinsi kubadilisha mfuatano wa DNA kubadilisha mlolongo wa amino asidi wa protini. Protini ni linajumuisha Tungo ndefu za amino asidi. Protini ni msimbo kwa katika DNA. DNA imeundwa aina nne tofauti za nucleotides.

Kuchunguza jinsi msimbo pachikwa katika DNA ni kutafsiriwa katika protini. Mchakato wa kugeuza taarifa katika DNA katika protini ni utaratibu tunakuhitaji, kuwashirikisha nakala na tafsiri. Katika nakala, nakala ya mRNA ni alifanya ya DNA.

Mtindo huu ni wa urekebishaji wa majaribio classic uliofanywa na Buri wa Peter (1956), ambayo kumbukumbu drift chembe za damu katika idadi ya maabara ya Drosophila.

Mfano huu rahisi simulates seining mkondo kwa ajili ya maisha ya wanyama. Aina kumi na sita ya; Safisha uti wa mgongo chini ya mkondo. Wakati ya mto seine ni wazi wanaweza kupata hawakupata na kutengwa katika ndoo.

Mtindo huu simulates MacArthur & amp; Wilson 1963 kisiwa cha biojiografia Msawazo karatasi. Unaweza kuendesha majaribio virtual kuchezea yafuatayo: kisiwa ukubwa, umbali kutoka bara, aina ya makazi, na aina aina (mfano ndege, wadudu, n.k.).

Kuchunguza jinsi nakala ya mRNA ni alifanya ya DNA. Protini complexes tofauti helix DNA ili kuruhusu nyongeza mRNA nucleotides kwenye mfuatano wa DNA. Pairing nucleotides ni maalum sana.Lengo la kimsingi la maabara ni:1) kujifunza kuhusu DNA na nucleotides

Kuchunguza jinsi protini ni alifanya kutoka mlolongo wa mRNA. Katika tafsiri, mRNA wa majani ya kiini na inaona kwa ya ribosome. Molekuli ya RNA uhamisho (tRNA) kuleta amino asidi ya ribosome.
