Egg come first in this world or hen come first
Answer:
first man came
good morning
Eggs come from chickens and chickens come from eggs: that’s the basis of this ancient riddle. But eggs – which are just female sex cells – evolved more than a billion years ago, whereas chickens have been around for just 10,000 years. So the riddle is easily solved…or is it?
Taken at face value, there is no doubt that the egg came before the chicken. We tend to think of eggs as the shelled orbs laid by birds from which their chicks hatch – unless we eat them first. But all sexually reproducing species make eggs (the specialised female sex cells). That’s 99.99 per cent of all eukaryotic life – meaning organisms that have cells with a nucleus, so all animals and plants, and everything but the simplest life forms.
We don’t know for sure when sex evolved but it could have been as much as 2 billion years ago, and certainly more than 1 billion. Even the specialised sort of eggs laid by birds, with their tough outer membrane, evolved more than 300 million years ago.
As for chickens, they came into being much later. They are domesticated animals, so evolved as the result of humans purposefully selecting the least aggressive wild birds and letting them breed. This seems to have happened in several places independently, starting around 10,000 years ago.
The wild ancestor of chickens is generally agreed to be a tropical bird still living in the forests of Southeast Asia called the red junglefowl – with other junglefowl species possibly adding to the genetic mix. From these origins, humans have carried chickens around the world over the past two millennia or more.
So, eggs dramatically predate chickens. But to be fair to the spirit of the riddle, we should also consider whether a chicken’s egg predates a chicken. As humans consistently chose the tamest red junglefowls and bred them together, the genetic makeup of the resulting birds will have shifted. At some stage during this domestication process the red junglefowl (Gallus gallus) evolved into a new subspecies, Gallus gallus domesticus, AKA the chicken.
In practice, it is impossible to pinpoint the moment when this happened. But in theory, at some point two junglefowl bred and their offspring was genetically different enough from the species of its parents to be classified as a chicken. This chicken would have developed within a junglefowl egg and only produced the very first chicken’s egg on reaching maturity. Looked at this way, the chicken came first.....

canten alguna historia de 5 párrafos pls no tengo nada es para un trabajo
Answer:
Libertad.
(En Cinco Parrafos)
Es una vida un casquillo de bala
talvez la misma que nos cuadra,
anterior al soplido seco de muerte.
Esa vida, la misma, una cabala
que con la suerte fuerte ladra,
para conseguir como no obtenerte.
Quiere como conquistarte sin medidas,
escondiendo amores pecaminosos,
como las teas de ocote prendidas.
Bailara a tus sones sobre los cosos,
y las brasas viejas pondrán confundidas
a los retoños de los ojos humosos.
Canta antes que la vida se acabe
canta con la suavidad de los sones
viene el final y todo se acerca
la libertad se ha conseguido con amor.

The key factor in the decision of the United States to enter World War I was its long-standing friendship with Great Britain. its desire to acquire German colonies in the Pacific. the political ambition of Woodrow Wilson. Germany's resumption of unrestricted submarine warfare against the United States.
Answer:
Germany's resumption of unrestricted submarine warfare against the United States.
Explanation:
The world War I (WWI) was a period of battle between various countries from 1914 to 1918. It started formally on the 28th of July, 1914 and ended on the 11th of November, 1918.
The key factor which prompted and influenced the decision of the United States of America to enter World War I (WWI) was because Germany resumed the use of unrestricted submarine warfare against the United States.
A subchaser also known as a submarine chaser refers to a little but very fast naval vessel which was designed specifically for anti-submarine warfare during the World War I.
During the World War II by late 1942, the German submarines (U-boats) were destroyed by the U.S Navy subchasers in the Atlantic. The subchasers that was used by the U.S Navy were the SC-497 class and PC-461 class subchasers which had anti-aircraft guns and machine guns.

Describe the different hypothesis (Nebular Hypothesis, Planetesimal Theory, and Tindal Theory) explaining the origin of solar system.
Answer:
Nebular Hypothesis:
According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust. Then, about 4.57 billion years ago, something happened that caused the cloud to collapse. This could have been the result of a passing star, or shock waves from a supernova, but the end result was a gravitational collapse at the center of the cloud.
From this collapse, pockets of dust and gas began to collect into denser regions. As the denser regions pulled in more and more matter, conservation of momentum caused it to begin rotating, while increasing pressure caused it to heat up. Most of the material ended up in a ball at the center while the rest of the matter flattened out into disk that circled around it. While the ball at the center formed the Sun, the rest of the material would form into the protoplanetary disc.
The planets formed by accretion from this disc, in which dust and gas gravitated together and coalesced to form ever larger bodies. Due to their higher boiling points, only metals and silicates could exist in solid form closer to the Sun, and these would eventually form the terrestrial planets of Mercury, Venus, Earth, and Mars. Because metallic elements only comprised a very small fraction of the solar nebula, the terrestrial planets could not grow very large.
Planetesimal Theory:
The planetesimal theory, put forth by Viktor Safronov in 1941, explains planet formation in the early solar system from accretion of small bodies, growing in size as gravity attracted more and more objects. As the small bodies orbit, their gravity is very weak and they must rely on non-gravitational forces to stay together, such as radiation pressure and the emission of thermal photons.
Growth of the small planetesimal caused the strength of its gravity to increase. Growth to approximately one kilometer in size allowed the gravity of planetesimals to attract objects to them, increasing their size to seeds for planetary formation.
Collisions were common during the formation of the solar system and planets. Planetesimals continually collided and destroyed each other, but some planetesimals were able to withstand the impacts and grow, eventually forming into planets.
In contrast, the giant planets (Jupiter, Saturn, Uranus, and Neptune) formed beyond the point between the orbits of Mars and Jupiter where material is cool enough for volatile icy compounds to remain solid (i.e. the Frost Line). The ices that formed these planets were more plentiful than the metals and silicates that formed the terrestrial inner planets, allowing them to grow massive enough to capture large atmospheres of hydrogen and helium. Leftover debris that never became planets congregated in regions such as the Asteroid Belt, Kuiper Belt, and Oort Cloud.
Tidal Theory:
involving the approach near the Sun of another star. This set up tidal forces, and the instability of the Sun resulted in part of its mass being torn off to form the planets. The theory was proposed by Sir James H. Jeans (1877–1946) and Sir Harold Jeffreys.

Presently they descried people, naked, and the Admiral landed in the boat, which was armed, along with Martin Alonzo Pinzon, and Vincent Yanez his brother, captain of the Nina. . . . The Admiral called upon the two Captains, and the rest of the crew who landed, as also to Rodrigo de Escovedo notary of the fleet, and Rodrigo Sanchez, of Segovia, to bear witness that he before all others took possession (as in fact he did) of that island for the King and Queen his sovereigns, making the requisite declarations, which are more at large set down here in writing. Numbers of the people of the island straightway collected together. Here follow the precise words of the Admiral: "As I saw that they were very friendly to us, and perceived that they could be much more easily converted to our holy faith by gentle means than by force, I presented them with some red caps, and strings of beads to wear upon the neck, and many other trifles of small value, wherewith they were much delighted, and became wonderfully attached to us. Afterwards they came swimming to the boats, bringing parrots, balls of cotton thread, javelins, and many other things which they exchanged for articles we gave them, such as glass beads, and hawk's bells; which trade was carried on with the utmost good will. But they seemed on the whole to me, to be a very poor people. . . . Weapons they have none, nor are acquainted with them, for I showed them swords which they grasped by the blades, and cut themselves through ignorance. They have no iron, their javelins being without it, and nothing more than sticks, though some have fish-bones or other things at the ends. They are all of a good size and stature, and handsomely formed. I saw some with scars of wounds upon their bodies, and demanded by signs the of them; they answered me in the same way, that there came people from the other islands in the neighborhood who endeavored to make prisoners of them, and they defended themselves. I thought then, and still believe, that these were from the continent. It appears to me, that the people are ingenious, and would be good servants and I am of opinion that they would very readily become Christians, as they appear to have no religion. They very quickly learn such words as are spoken to them. If it please our Lord, I intend at my return to carry home six of them to your Highnesses, that they may learn our language." These are the words of the Admiral.
Explanation:
Naked,friendly, and very poor.

O domínio da metrópole portuguesa sobre sua colônia na América submeteu os colonos a condições impostas que, na maioria das vezes, oportunizaram apenas os interesses de Portugal. A exploração excessiva que era realizada por Portugal teve seus reflexos de descontentamento a partir do final do século XVII. Neste, ocorreu apenas um movimento de revolta, mas foi ao longo do século XVIII que os casos se multiplicaram. Entre os principais movimentos nativistas podemos destacar a Revolta dos Beckman, a Guerra dos Mascates, a Guerra dos Emboabas e a Revolta de Filipe dos Santos. Sobre essas revoltas, pesquise em diferentes fontes e preencha o quadro abaixo com as informações solicitadas.
Answer:
A Revolta dos Beckman de 1648 ocorreu no
Maranhão, seu motivo foi a foi a insatisfação
coletiva com a Companhia de Comércio do
Maranhão, que controlava os preços dos
produtos na região, prejudicando a todos os
maranhenses de São Luís, prejudicando os
agricultores locais.
Os irmãos Beckman, fazendeiros ingleses,
iniciaram uma revolta que conseguiu
atacar as instalações da CIA de Comércio
do Maranhão e a capital da Capitania,
apossando-se dos suprimentos. Porém a
Coroa Portuguesa logo enviou reforços que
prenderam os responsáveis, punindo-os.
A Guerra dos Mascates aconteceu em
1710 na província de Pernambuco, sendo
que mascates eram os comerciantes, que
confrontaram os senhores de engenho.
Pode-se dizer que houve uma vitória
simbólica dos mascates e a anistia dos
envolvidos pela coroa portuguesa.
