crop rotation kepy different plants in the soil instead of once constintly. when switching out plants you have different nutrients being absorbed at different speeds and different roots growing differently therfore the spoil and water flow have to adapt and carry fresh nutrients to carry the constant changes that were going on in the soil.

because everyone tends to get their feelings hurt if they don't agree with something someone is doing and vice versa. it's a major issue that needs to be dealt with, especially in the christian society. everyone thinks that christians hate gay people, because it is a sin, and christians "just hate everyone who sins and every one is going to hell for sinning"(saying that all in a sarcastic tone but i'm just going to go ahead and tell you why everything with that type of view on christians is wrong.

#1. christians do not hate gay people. and if they do, then that is their own personal problem. christians are not supposed to hate anyone. if you hate a neighbor (or any person basically), then that is as if you are hating jesus.

#2. being gay is in fact a sin according to the holy bible. it is in genesis. and no, the fact that it is a sin, does not mean that god hates you. he is grieved that a person is sinning against his word, but he still loves that person. in fact, christians are supposed to love everyone. we are supposed to love our enemies, but hate the sin they are doing. we love you and respect you, but we do not agree with every decision you make, is basically what i'm trying to say.

hope this you ! (:

sorry i cant

answer:   migrations were important in the neolithic period. "two major migrations passing through southeastern europe were confirmed by the means of archaeo-genetic studies."

the first migration was the early neolithic period -- 6,000 before common era (bce) -- when the first farmers, from anatolia -- asia minor -- spread through europe. the second migration occurred during the early bronze age (3,000-2,500 bce) when the so-called "steppe population," from the eurasian steppe, replaced much of northern europe's previous population.

the first farmers of northern and western europe passed through southeastern europe with limited hunter-gatherer genetic admixture, which occurs when two or more previously isolated populations begin interbreeding. however, some groups that remained mixed extensively -- without the male-biased, hunter-gatherer admixture that prevailed later in the north and west, according to latest discoveries. southeastern europe continued to be a nexus between east and west, with intermittent genetic contact with the steppe people up to 2,000 years before the migrations that replaced much of northern europe's population.

"in some places, hunter-gatherers and incoming farmers seem to have mixed very quickly," says iain mathieson, a geneticist at the university of pennsylvania, who was first author of the paper. "but, mostly, the two groups remained isolated, at least for the first few hundred years. these hunter-gatherers had been living there for thousands of years, and it must have been quite a shock to have these new people show up -- with a completely different lifestyle and appearance."
