I. O processo migratório é o principal fator que influencia a diversidade genética nas populações humanas, uma vez que a troca de genes entre grupos é a principal fonte de variação genética.
II. A seleção natural é um fator que diminui a diversidade genética das espécies em geral, uma vez que os genes mais adaptativos são selecionados e se tornam mais comuns na população.
III. A mutação é o principal fator que influencia a diversidade genética nas populações humanas, uma vez que é a fonte primária de novas variantes genéticas.
IV. Assim, como a mutação, a deriva genética é um fator que favorece a diversidade genética nas populações humanas, principalmente em grupos com poucos indivíduos.

“Especiação, a multiplicação das espécies, consiste na evolução de barreiras genéticas à troca gênica entre populações. Isso provavelmente ocorre de modo mais frequente por e entre populações segregadas espacialmente ( e ), mas a especiação é possível, ao menos em teoria. As espécies existem não em virtude da diferenciação completa de todo o genoma, mas em razão de barreiras reprodutivas que apresentam os mesmos tipos de bases genéticas que as características que variam dentro das populações”.

Texto III
Presa do ódio (Cruz e Souza)
Da tua alma na funda galeria
Descendo às vezes, eu às vezes sinto
Que como o mais feroz lobo faminto
Teu ódio baixa de alcateia espia.
Do desespero a noite cava e fria,
De boêmias vis o pérfido absinto
Pôs no teu ser um negro labirinto,
Desencadeou sinistra ventania.
Desencadeou a ventania rouca,
Surda, tremenda, desvairada, louca,
Que a tua alma abalou de lado a lado,
Que te inflamou de cóleras supremas
E deixou-te nas trágicas algemas
Do teu ódio sangrento acorrentado!

When you hear the term computers, it’s difficult to imagine different devices from a laptop or a small desktop. Believe it or not, they weren’t always like they are today. They used to be very large and heavy, sometimes as big as an entire room. Some technology professors historically define computers, as “a device that can help with computations”. The word computation involves counting, calculating, adding, subtracting, etc. The modern definition of a computer is a little wider, because in our day and age, computers store, compile, analyze and compute an enormous amount of information. Ancient computers were very interesting. Actually, the first computer may have been located in Great Britain, at Stonehenge. It is a man-made circle of large stones. Citizens used it to measure the weather and forecast the change of seasons. Some specialists say that another ancient computer is the abacus. It was used by the early Romans, Greeks, and Egyptians to count and calculate. Even though they are no longer in use, certainly, these early devices are fascinating. Computers are embedded in our history and some people say that we are completely dependent of them. No matter the complexity of the task, easy or difficult, some people can’t do anything without them. Do you contest or share this opinion?

I. the made-man circle - the inversion of a noun (man) with an adverb (made) is one of the possibilities for forming noun groups with an emphasis on adjectives.
II. circle of large stones – the preposition 'of' is an indication that the previous word is a verb.
III. large stones – the position of the adjective (large) before the noun (stones) is one of the possible formations of the order of adjectives.
