The elimination of wolves from Yellowstone National Park had profound impacts on the trophic pyramid. Without predation, herbivores began to over-graze many woody browse species, affecting the area's plant populations. In addition, wolves often kept animals from grazing in riparian areas, which protected beavers from having their food sources encroached upon. The removal of wolves had a direct effect on beaver populations, as their habitat became territory for grazing. Furthermore, predation keeps hydrological features such as creeks and streams in normal working order. Increased browsing on willows and conifers along Blacktail Creek due to a lack of predation caused channel incision because they helped slow the water down and hold the soil in place.
Broader ecological impacts can occur when an apex predator is removed, in the case of Yellowstone, this includes alteration to the?
****
The answer: hydrological features

In the Pre-Modern era, many people's sense of self and purpose was often expressed via a faith in some form of deity, be that in a single God or in many gods. Pre-modern cultures have not been thought of creating a sense of distinct individuality, though. Religious officials, who often held positions of power, were the spiritual intermediaries to the common person. It was only through these intermediaries that the general masses had access to the divine. Tradition was sacred to ancient cultures and was unchanging and the social order of ceremony and morals in a culture could be strictly enforced.
Peoples sense of worth was expressed through what in the Pre-modern era?
****
The answer: via a faith in some form of deity

To allow for agricultural development of the Great Plains and house a growing population, the US passed the Homestead Acts of 1862: it allowed a settler to claim up to 160 acres (65 ha) of land, provided that he lived on it for a period of five years and cultivated it. The provisions were expanded under the Kinkaid Act of 1904 to include a homestead of an entire section. Hundreds of thousands of people claimed such homesteads, sometimes building sod houses out of the very turf of their land. Many of them were not skilled dryland farmers and failures were frequent. Much of the Plains were settled during relatively wet years. Government experts did not understand how farmers should cultivate the prairies and gave advice counter to what would have worked[citation needed]. Germans from Russia who had previously farmed, under similar circumstances, in what is now Ukraine were marginally more successful than other homesteaders. The Dominion Lands Act of 1871 served a similar function for establishing homesteads on the prairies in Canada.
how much land did the Homestead Act allow a person to claim?
****
The answer: up to 160 acres

Luis Cabral, brother of Amilcar and co-founder of PAIGC, was appointed the first President of Guinea-Bissau. Following independence, the PAIGC killed thousands of local Guinean soldiers who had fought along with the Portuguese Army against guerrillas. Some escaped to settle in Portugal or other African nations. One of the massacres occurred in the town of Bissora. In 1980 the PAIGC acknowledged in its newspaper No Pintcha (dated 29 November 1980) that many Gueinean soldiers had been executed and buried in unmarked collective graves in the woods of Cumera, Portogole, and Mansaba.
Who was the first President of Guinea-Bissau?
****
The answer:
Luis Cabral
