I love taking care of nature. I usually take care of house plants. sometimes look after the flowers that grow near our house. I never pluck the leaves on the trees and bushes. I always throw garbage in trash. You can not break branches of trees and pluck the rare flowers that are listed in the Red Book. many people neglect our nature. nature nowadays unfortunately very polluted. Take care of nature!!

What things can you describle as marvels of modern science?
Какие вещи вы можете описать как чудеса современной науки?
Ответ:Я считаю, что к чудесам современной науки может относится ультразвук.
Ультразву́к — упругие колебания в среде с частотой за пределом слышимости человека. Обычно под ультразвуком понимают частоты выше 20 000 герц.
Хотя о существовании ультразвука известно давно, его практическое использование достаточно молодо. В наше время ультразвук широко применяется в различных физических и технологических методах. Так, по скорости распространения звука в среде судят о её физических характеристиках. Измерения скорости на ультразвуковых частотах позволяет с весьма малыми погрешностями определять, например, адиабатические характеристики быстропротекающих процессов, значения удельной теплоёмкости газов, упругие постоянные твёрдых тел.
На уровне биотехнологии и здравоохранении также можно отнести Генетическую инженерию,имплантаты и протезы, регенеративная медицина, роботизированная хирургия,тканевая инженерия, пересадка головы, изолированный мозг, наномедицина.
I believe that the wonders of modern science may include ultrasound.Ultrasound - elastic vibrations in the environment with frequency outside the human hearing. Usually, the higher the frequency of ultrasound understand 20,000 hertz.Although the existence of ultrasound has long been known, its practical use quite young. Today, ultrasound is widely used in a variety of physical and technological methods. Thus, the speed of sound in the environment is judged on its physical characteristics. Speed measurements at ultrasonic frequencies allows very small error is determined, for example, adiabatic characteristics of fast processes, the value of the specific heat of gases, the elastic constants of solids. at the level of biotechnology and health careGeneticheskauyu also include engineering, implants and prostheses, regenerative medicine, robotic surgery, tissue engineering, transplantation of the head, isolated brain Nanomedicine.
And why are they such?
И почему они такие?
Они такие именно потому, что они универсальны и необходимы в жизни определенных людей, которые имеют определенные проблемы со здоровьем. Это своего рода человеческая необходимость, рука "новой помощи" в современном обществе.
They are the very reason that they are universal and necessary in the life of certain people who have certain health problems. It is a kind of human need, the hand of the "new aid" in modern society.
