3 The biologist is engaged in researches of a plant and animal life of Earth. It studies all aspects of life of live organisms of Earth, their structure, growth, development, an origin, evolution and distribution on a planet. It classifies and describes living beings, studies interaction of types with each other.
4 Activity of this scientist depends on his specialization. Botanists study flora, zoologists – animal, anatomists and physiologists – a human body, microbiologists – unicells, and it is not all directions. In addition, it has to have knowledge from area of chemistry, physics, ecology, medicine, and also basic knowledge of Latin.
5 Most often the working day of the biologist passes in the room: in laboratory, clinic, on production. It collects necessary materials, substances and tests of materials. Applying any devices and the equipment, makes experiments and the researches which results will be applied in a certain branch. Except laboratory works in nature and business trips in places of growth of certain species of plants and dwelling of
