Life is a characteristic that distinguishes physical entities that have biological processes , such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased they have died , or because they never had such functions and are classified as inanimate. Various forms of life exist, such as plants , animals , fungi , protists , archaea , and bacteria. Biology is the science concerned with the study of life. There is currently no consensus regarding the definition of life.

Animals also called Metazoa are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material , breathe oxygen , are able to move , can reproduce sexually , and grow from a hollow sphere of cells, the blastula , during embryonic development. Over 1. Animals range in length from 8. They have complex interactions with each other and their environments, forming intricate food webs. The kingdom Animalia includes humans but in colloquial use the term animal often refers only to non-human animals.

Respiratory system , the system in living organisms that takes up oxygen and discharges carbon dioxide in order to satisfy energy requirements. In the living organism, energy is liberated, along with carbon dioxide, through the oxidation of molecules containing carbon. The term respiration denotes the exchange of the respiratory gases oxygen and carbon dioxide between the organism and the medium in which it lives and between the cells of the body and the tissue fluid that bathes them. With the exception of energy used by animal life in the deep ocean, all energy used by animals is ultimately derived from the energy of sunlight. The carbon dioxide in the atmosphere in conjunction with the energy of sunlight is used by plants to synthesize sugars and other components. Animals consume plants or other organic material to obtain chemical compounds , which are then oxidized to sustain vital processes. This article considers the gaseous components of air and water, the natural respiratory habitats of animals, and the basic types of respiratory structures that facilitate gas exchange in these environments.

A review of the literature is presented that gives a background to the human sense of smell, then the importance of learnt and innate olfactory cues in animal behaviour. Some possible roles for natural products chemists interested in the interaction between animals and plants are discussed. Natural Products chemists are conspicuous when they are wandering in the bush. They habitually break pieces from plants, rub them between their fingers, and smell them. They are the people who become animated only if they detect an interesting odour; whether it be new, unusual, pleasant, or unpleasant.

Life is self-contained, self-sustaining, self-replicating, and evolving, operating according to laws of the physical world, as well as genetic programming. Life scientists use observations, experiments, hypotheses, tests, models, theory, and technology to explore how life works.

Интересно, почему Стратмор его до сих пор не отключил. Ему понадобилось всего несколько мгновений, чтобы принять решение. Фонтейн схватил со стола заседаний трубку внутреннего телефона и набрал номер шифровалки. В трубке послышались короткие гудки. В сердцах он швырнул трубку на рычаг.

 - Потом в его голосе зазвучали зловещие нотки.  - Но как только я узнаю, что вы следите за мной, я немедленно расскажу всю эту историю журналистам. Я расскажу, что Цифровая крепость - это большая липа, и отправлю на дно все ваше мерзкое ведомство.

Первая попытка закончилась неудачей. Нахмурившись, Беккер набрал второй номер. И на другом конце сразу же сняли трубку. - Buenas noches, Mujeres Espana.
