Growth, according to Smith, is rooted in the increasing division of labor. This idea relates primarily to the specialization of the labor force, essentially the breaking down of large jobs into many tiny components. Division of labor also implies assigning each worker to the job that suits him best.
Hopes this helps :) mark brainlist pls
I believe the answer is: <span>bones and stones
The utilisation of metal as materials to made tools did not begin until the Neolithic period (approximately 2000 years after the Mesolithic period)
</span><span>So, bones from wild animals and stones are the only material that they know to be strong/hard enough to be made as tools.</span>
The answer is that "it is reinforced based on a <span>fixed-interval schedule".
</span>
A Fixed Interval Schedule gives a reward at reliable circumstances. For example a kid might be rewarded once per week if their room is tidied up. A problem with this sort of fortification timetable is that people tend to hold up until the point that the time when support will happen and then begin their reactions. Due to this reinforcement, yield doesn't stay steady. For example, Educator plans exams or undertakings at general interims and the grade is the reinforced, yet the work is inconsistent during the interim between tests.
