Ответ:

1)если простейшие исчезнут, ощутимо это будет на земле? Да, простейшие бактерии не будут очищать воду от грязи, ими перестанут питаться другие животные. Они являются продуцентами в цепи питания.2)Подводя итоги, можно сказать, что если на планете Земля моментально исчезнут все бактерии и вирусы, то произойдет форменный апокалипсис.3)Деление на вредоносных и не вредоносных -- условное.

Да, особо выдающиеся иногда удаётся уничтожить -- оспа, например.

Но уничтожить всё невозможно. У вирусов и бактерий в целом важнейшая роль в системе. В том числе в работе организмов людей, в эволюции. Одни и те же могут быть и полезны, и вредны. Нейтральные и полезные могут легко стать вредными.

Помогите перевести!!!!!!!!!!!! По предложениям!
Captain Hook and his men, Starkey and Smee, looked around, but they didn’t see the entrances to the Lost Boys’ house.

“Look everywhere!” said Hook. “I want those boys, and I want Peter Pan. He will be sorry that he cut off my hand!”

“But your hook is better than a hand, sir,” said Smee. “You said you can comb your hair and do lots of jobs with it! Why are you angry with Peter?”

“Peter threw my hand to the crocodile!” said Hook. “The crocodile liked the taste so much that now he wants to eat the rest of me!”

“Ah!” said Starkey. “So that is why the crocodile follows you everywhere.”

“Yes,” said Hook. “But luckily for me, the crocodile swallowed a clock. Now I can hear it every time it comes near me.”

“One day the clock will stop,” said Smee. “Then the crocodile will get you.”

“That is what I’m afraid of,” said Hook. He sat down on a large mushroom to rest, but then he jumped up again.

“That mushroom is hot!” he said. The pirates looked at the mushroom and saw that smoke was coming out of it.

“It’s a chimney!” cried Hook. “This is where the Lost Boys live!”
The pirates listened, and they heard the voices of the Lost Boys. The boys felt safe in their house, and they were chatting happily.

“Did you hear them say Peter Pan’s not at home?” Smee whispered.

“I did,” said Hook with an evil grin. “I have a plan! We will go back to the ship and make a big cake with green sugar on the top. We will leave the cake on the shore of the Mermaids’ Lagoon, and it will become damp. The boys often swim in the lagoon. When they see the cake, they will eat it. The Lost Boys have no mothers, and they don’t know how dangerous it is to eat damp cake! Ha-ha-ha! They will all die!”

“It’s a brilliant plan!” cried Smee, and the pirates danced and sang. But suddenly, they heard a terrible sound.

Tick, tick, tick, tick!

Hook froze with one foot in the air.

“The crocodile!” he cried, and ran away as fast as he could, back to the pirate ship. Starkey and Smee followed, and for a while, they forgot all about the Lost Boys and the underground house.
