Dit beteken dat die bal van die voet en veral die groottoon ‘n belangrike rol tydens beweging speel.

Bekkengordels en dybene. Die ooreenkoms tussen Australopithecus en die mens is duidelik. Die vertikale swart streep G dui die as aan waarlangs die gewig van die heup na die knie oorgedra word. A = os illium (heupbeen), B = potjie vir dybeen, C = os pubis (skaambeen), D = os ischium (sitbeen), E = os sakrum, F = os femur (dybeen

BRON E

By Australopithecus was die kniegewrigte reeds na binne gebuig soos by hedendaagse mense en het hulle spore soos ons getrap. Die Sjimpansee het met ‘n waggelgang op sy agterpote geloop.

Twaalf jaar later, in 1936, het dr. Robert Boom by Sterkfontein (naby Krugersdorp) die eerste skedel van ‘n volwasse gevind. Hy het eers gedink dat dit die vroulike vorm van ‘n nuwe spesie was en dit Plesianthropus transvaalensis (Mev. Ples) genoem. Verdere ondersoek het egter getoon dat Mev. Ples feitlik identies aan die Taungkind was.

Aktiwiteit 2:

Om tyd te verstaan deur aan te toon dat sekere aspekte in gemeenskappe verander het, terwyl ander dieselfde gebly het

[lu 2.1]

a) Bestudeer meegaande skets uit die steentydperk en beantwoord die vrae wat volg. Maak eers ‘n skets van soortgelyke omstandighede by jou huis.

  • Is dit moeilik om kos te bekom? Word kos met mekaar gedeel?
  • Watter klere dra hulle?
  • Hoe werk hul familielewe? Het hul omgegee vir hul kinders?
  • Watter toerusting en wapens word gebruik? Het die tegnologie daaraan verbeter?
  • Kan hul snags veilig slaap?
  • Het die mans en vrouens verskillende werke ?
  • Bly die mense lank op ‘n plek?

b) Ontwikkel ‘n strokiesprent of luisterliedjie om bogenoemde inligting mee saam te vat.

Memorandum

Aktiwiteit 1

Ape toon duidelike verskille met mense. Die mens is die enigste van die primate wat regop loop . Die vorm van die bekkengordel, die posisie van die dybeen en die maniere waarop die voet geplant word, is baie spesifiek. ‘n Vergelyking van die bou van die res van die liggaam en die brein toon ook dat die Australopithecus beslis nader aan mense verwant is Daar was dus ‘n ontwikkelingspatroon vanaf Australopithecus deur Homo habilis en Homo erectus na die hedendaagse mens Homo sapiens .

Aktiwiteit 2

Gestel hierdie skets is ‘n voorstelling van die Steentydperk :

Hulle woon in grotte , waarin hulle slaap en kos bêre en werktuie, wapens en vure gebruik. Die insameling van kos was die hoofbedrywigheid. Die mans het gejag en visgevang. Die vroue en kinders het bessies, wilde vrugte en plantwortels gesoek. Hulle het ook kos gebêre vir die winter en ook die kos gaargemaak. Werktuie was van been, klip en hout en het algaande verbeter, want hulle het pyle, byle en dolke gemaak. Hulle kon ook eenvoudige voorwerpe vervaardig, bv. “naalde” waarmee klere van wol en vlas gemaak is. Die vroeë mense het nie lank op een plek gebly nie.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

or infinite solutions?

The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments

name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

not now but maybe in future only AgNP maybe any other nanomaterials

can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
