and
29 is D
Explanation:
29.The act represented the first major attempt to restrict immigration into the United States. The establishment of a quota system limited immigration from southern and eastern Europe (primarily Jewish and Slavic) while allowing significant immigration from northern and western Europe. Asians were specifically excluded from immigration.
28.With revolutions in shipping technology and a growing reliance on a network of migrant finance, migration costs declined in the mid-nineteenth century, ushering in a sustained Age of Mass Migration from Europe (1850-1920). This period ended with the imposition of a literacy test for entry in 1917 and strict immigration quotas in 1921, which were modified (although not eliminated) in 1965.
The rise of mass migration was associated with the shift from sail to steam technology in the mid-nineteenth century, and a corresponding decline in the time of trans-Atlantic passage. As travel costs fell and migrant networks expanded from 1800 to 1850, the number of unencumbered immigrants entering the US increased substantially. Annual in-migration rose from less than one per 1,000 residents in 1820 to 15 per 1,000 residents by 1850

Answer:
This work studies the adsorption of colored compounds in cane juice using a food-grade macroporous adsorber resin without functional groups. The adsorption equilibrium was studied through the adsorption isotherms at 30, 40, and 50 ℃. The absorbance at 420 nm was used to measure the concentration of colored compounds, which enables correlation of the residual concentration with the adsorbed concentration. Furthermore, the efficiency of the adsorption process was studied, from which it was observed that there was an improvement in efficiency with increasing resin content, while the increase in temperature was less important in the process. The kinetic study was performed using the Ibarz model and intraparticle diffusion model, which correctly account for the kinetics of the adsorption process. The adsorption kinetic constant was always greater than the desorption kinetic constant, indicating that the adsorption step predominates over the desorption step.Explanation:
