What is Animal(I)

Well, today let us know about what is animal through its basic knowledge. Animal always are human’s friends which live with people together on the earth. According to zoologists and biologists’ research and discovery, we have known a lot of new species we never know before. Actually, Human also belongs to animal, merely we are higher animals with wisdom may change world. By this time let us understand the basic information about what is animal?Steel Pipe

Brief

Animal taxonomists classify animals according to their various characteristics (morphology, cell, heredity, physiology, ecology, geographical distribution, etc.), and divide them into six main classes in turn, namely, phylum, class, order, family, genus and species.

According to fossil studies, the earliest animals on Earth originated from the oceans. After a long geological period, early marine animals gradually evolved various branches, enriching the early life forms of the Earth.

Before the emergence of human beings, prehistoric animals had appeared and flourished in their respective periods of activity. Later, they became extinct in a changing environment. However, the animals on the earth continue to evolve and multiply from low to high, from simple to complex, and have diversity today.

Do You Know About The War of Spartacus(II)

Background of the war of Spartacus

In ancient Rome, everywhere, there were manors that used slave labor on a large scale. Meanwhile, the slaves were called “tools may speak”.

Slave owners built huge arenas (Colosseum) for pleasure and amused for family members, forced slaves to fight against each other, and let gladiators fight each other with sword and dagger. After a fight, so many slave’s bodies were left on the court. The brutal rule of slave owners forced the slaves to launch large-scale armed uprisings again and again.Steel Tube Manufacturers

The main reason for the uprising of slaves was class contradictions within the Roman slave society (i.e. between slave owners, and the slaves were deprived of their human rights and cruelly exploited).

About Spartacus

Spartacus was captured and enslaved in an anti-Roman war. Because of his intelligence, education and strong physique, his master sent him to Gladiator school to train him to be an excellent gladiator.

At Gladiator School, Spartacus became the spiritual leader of gladiators with his courage and wisdom. He took every opportunity to persuade gladiators to die for freedom, not to be the victim of the pleasure of the Roman aristocracy.

When he organized more than 200 gladiators to prepare for the riot and uprising, accidentally spill the beans and secretive action cannot keep forward, so he decided to move ahead. As a result, about 78 people rushed out of the jail.

Insurrection process

From the end of 74 B.C. to the beginning of 73 B.C., the Spartacus Rebellion grew rapidly, hosting a large number of escaped slaves, gladiatorial soil, bankrupt peasants and soldiers escaping from the Roman Legion in Campania, amounting to 10,000 people, who defeated many small units of the Roman Army for many times. The uprising spread from Campagna to Aprilia, Lucania (Basilicata) and Brutium in southern Italy.

Nature About Host(II)

Host and Parasite

Basically, because parasites need to rely entirely on the host to provide nutrition and living environment, the ideal host-parasite relationship is that the host can provide a stable living environment for the parasite for a long time, while its own nutrition will not be absorbed by the parasite in large quantities. But often in the growth cycle of parasites, parasites continue to reproduce in the host, a large number of parasites gradually increase to absorb the nutrition of the host, so that the physical capacity of the host is weakened, and finally the host will suffer from long-term malnutrition, which will most seriously lead to the death of the host. The death of the host makes the parasite unable to absorb the nutrition of the host, and also causes the parasite to die successively because of the lack of nutrition.Steel Pipe

However, in general, the “host-parasite relationship” between the mother and the fetus does not lead to the death of the host due to over-absorption of host nutrients. Moreover, the fetus itself has no reproductive capacity and will not increase the pressure of the host to provide nutrition because the number of “parasites” (Fetus) increases in the “host” (mother). . And this “host parasite relationship” usually ends with the birth of the fetus and leaving the mother body.
