Soma taarifa hii kisha ujibu maswali
Licha ya kuwa na historia ya kiasi, maisha ya binadamu ni kioja kikubwa. Hebu jiulize jinsi uhai wako wewe mwenyewe ulivyoanza sembuse unavyoweza kupumua na kuishi siku nenda siku rudi.
Dini zimefahamisha kuwa sisi binadamu tumeumbwa na Mwenyezi Muumba. Hata hivyo muumba hutumia mume na mke kutuanzishia maisha yetu humu humu duniani. Uhai wa hapa duniani huanzia katika tumbo la mwanamke muda mfupi tu baada ya mume na mke kushirikiana katika tendo la kujamiana. Katika ngono hii yenye ufanisi, mbegu moja ya manii kutoka kwa mwanamume, hudunga na kujiingiza katika yai la mwanamke huku ikilirutubisha. Tangu hapo mtu huwa na mama akawa mjamzito. Hatua ya kwanza ya uhai!
Wanasayansi wametuthibitishia kuwa mbegu katika shahawa kutoka kwa mwanamume ina kromosomu ishirini na tatu (23) nalo yai la mwanamke lina idadi iyo hiyo ya kromosomu. Basi katika hatua ya kwanza ya uhai wake, binadamu ana kromosomu arubaini na sita (46).
Kromosomu hizo zote ndizo humfanya mtu kuwa mkamilifu kwa kukadiria mambo mbalimbali adhimu. Kwa mfano, kukadiria kama kiumbe kitakuwa cha kike au cha kiume, mtu mweupe au mtu mweusi, mwerevu au wa wakia chache, mwenye nywele za singa au za kipilipili, atakuwa na damu ya namna gani, michoro ya vidole vyake itakuwa vipi na hata utu wake utakuwa wa namna gani katika siku za usoni.
Elimu yote anayopata mtu kutoka kwa jamii na mazingira huweza tu kujenga juu ya yaliyokwisha kuanzilishwa na kromosomu katika yai lililorutubishwa tumboni.
Haihalisi kabisa kufikiria kwamba huwa katika hali ya ukupe. La hasha! Yeye hujitegemea kwa vyovyote na ana upekee wake. Hatangamani na mama yake. Roho yake humdunda mwenyewe na damu yake ambayo huenda ikawa tofauti kabisa na ya mama yake, humtembea na kumpiga mishipani mwake. Isitoshe, yeye si mojawapo katika viungo vya mwili wa mama yake vinavyomdhibiti katika himaya yake ndogo.
Amini usiamini, hapana binadamu hata mmoja ambaye amewahi kuwa sawa kimaumbile na mwingine na wala hatakuweko. Hata watoto pacha kutoka yai moja la mama hawawi sawa, lazima watofautiane. Si nadra kusikia mtu amepata ajali akahitaji msaada wa damu, na pakakosekana kabisa mtu hata mmoja kutoka jamaa yake wa kimwauni. Basi ukistaajabu ya Musa utaona ya Firauni.
1. Ipe taarifa uliosoma anwani mwafaka
2. Mwandishi ana maana gani anaposema ‘ngono yenye ufanisi’?
3. Uchunguzi wa sayansi umekita mizizi imani gani ya kidini?
4. Taja majukumu yoyote matano yanayotekelezwa na kromosomu
5. Katika makala, elimu kutoka kwa jamii na mazingira yaelekea kuwa bure ghali. Kwa nini?
6. Eleza maana ya maneno yafuatayo kama yalivyotumika katika makala:-
(i) huwa katika hali ya ukupe…
(ii) himaya
(iii) hatangamani na mama yake

a) Plot these data on apiece of graph paper provided
b) At what light intensity did the shoot produce ;
i) 18 bubbles per minute
ii) 25 bubbles per minute
c) Give two better ways of measuring the rate of photosynthesis than counting bubbles
d) What is the role of light intensity in photosynthesis
e) Account for the expected results of doing this experience at the following temperature;
i) 4ºC
ii) 34ºC

The table below shows the results of an experiment carried out to determine the rate of photosynthesis at different light intensities and varying Carbon (IV) oxide concentrations. The rate was determined by counting the number of bubbles per minute. The temperature was kept constant.
a) On a graph paper provided, draw a graph for each of the light intensities. All the three graphs should be plotted on the same axis (rate of photosynthesis on vertical axis and carbon (IV) oxide concentration on horizontal axis
b) What is the effect of an increase in carbon (IV) oxide concentrations and light intensities
c) Briefly explain how aquatic green plants meet light intensities and carbon (IV) oxide
requirement
d) Using the data provided in the table state two factors required by the green plants for food
production

CHIMBUKO LA USHAIRI
Ushairi ni fani kongwe kama mwanadamu mwenyewe alivyo mkongwe duniani. Na mashairi yamekuwepo kitambo sana hata kabla ya lugha ya Kiswahili bado haijanawiri na kushamiri kama ilivyo hivi leo. Ndipo tunasikia kuna mashiri ya kipemba, mashairi ya kimvita, mashairi ya kivumba, mashairi ya kipate, mashairi ya kiyunani, ya kirumi na kadhalika,. Almradi kila jamii na kila kabila lilikuwa na mashairi yake.
Katika utafiti na kongomano zao, wataalam wa arudhi za Kiswahili asili wamechambua na kufafanua kwamba mashairi ya Kiswahili asili yake ni nyimbo za jadi zilizokuwa zikiimbwa na manju, wangoi au waimbaji stadi wa tangu na tangu walipojumuika katika matukio na hafla mbalimbali kama za jando, arusi, matanga, ngoma na shangwe zao za maishani.
Nyimbo hizi zilitumiwa na watangulizi wetu, kidhamira hazikuhitalafiana hata kidogo na mashairi ya Kiswahili tunayohimiza wakati huu. Farka iko katika lugha na umbo kwani kila jamii ilitumia lugha yake na lahaja ya mazingira yake. Na kwa upande wa umbo, tungo hizo za awali kabisa hazikuwa na sanaa kwa maana ya ushauri tunauona leo. Bali tungo hizo zilijengeka katika nguzo mbili kuu. Kwanza ni uzito wa mawazo maadilifu ambayo yalitaamaniwa sana. Na pili ni mizani ya sauti ya manju kulingana na lahani, pumzi zake pamoja na madoido katika uimbaji ambao ulikuwa burudani naathari katika noyo za wasikilizaji wake.
Kwa kifupi ni kwamba, nyimbo hizo ziliuhifaid umma kwa njia mbili, mawaidha kwa mapana na taathira au jadhba kutokana na sauti tamu ya manju.
Kama utakubalika, basi huo ndio ushairi wa awali kabisa ullioambatana na nyimbo zetu za kienyeji. Kila kabila katika nchi zetu lilikuwa na ushauri wake au nyimbo zake zenye undani uliolenga sababu maalum na tukio maalum katika jamii.
Nyimbo kama hizo kwa jina la sasa tunaweza kuita mashairi ndizo zile zilizoitwa ‘mwali’ na wakamba; gichandi kwa ‘wakikuyu’; ‘gigia gi sigele’ kwa waluo na ‘wagashe’ kwa wasukuma zilikuwa na undani wa kipekee tena uliodidimia ambao si bure kutolewa hadharani.
Aina za mashairi ya watu wa mwambao ni kama lelemama, misemele, gungu, nyiso, kongozi n.k.

(a) Kongamano …
