There are three subjects like Physics, Chemistry, and Biology (life science) which comes in General Science. All these three subjects are very very important and scoring for all competitive examinations like SSC, RRB, JSSC, BSSC, PSU, IES, NTPC, BHEL, IOCL, etc.

Here we provide you the Basics of All three subjects i.e Biology, Physics and Chemistry.

Introduction to Biology

Biology is the study of living things. It encompasses the cellular basis of living things, the energy metabolism that underlies the activities of life, and the genetic basis for inheritance in organisms. Biology also includes the study of evolutionary relationships among organisms and the diversity of life on Earth. It considers the biology of microorganisms, plants, and animals, for example, and it brings together the structural and functional relationships that underlie their day-to-day activities. Biology draws on the sciences of chemistry and physics for its foundations and applies the laws of these disciplines to living things.

Many subdisciplines and special areas of biology exist, which can be conveniently divided into practical and theoretical categories. Types of practical biology include plant breeding, wildlife management, medical science, and crop production. Theoretical biology encompasses such disciplines as physiology (the study of the function of living things), biochemistry (the study of the chemistry of organisms), taxonomy (classification), ecology (the study of populations and their interactions with each other and their environments), and microbiology (the study of microscopic organisms).

PATTERN OF THE COMBINED GEOSCIENTIST AND GEOLOGIST EXAMINATION (NOW WILL BE RENAMED AS COMBINED GEO-SCIENTIST EXAMINATION)

The Union Public Service Commission in consultation with the Government (Ministry of Mines, the Nodal Ministry) has decided to revise the Scheme, Pattern and Syllabi of the Combined Geo-Scientist and Geologist Examination.

The salient features of the same are as under:

(i) The nomenclature of this Examination has been changed to “Combined Geo-Scientist Examination” in place of “Combined Geo-Scientist and Geologist Examination”.

(ii) There will a three tier examination pattern i.e.

(i) Stage-I : Preliminary Examination

(ii) Stage-II : Main Examination

(iii) Stage-III : Personality Test.

(iii) Preliminary Examination will screen the candidates for taking the Main Examination (Stage–II).

(iv) The Preliminary Examination will be of objective type having two Papers. Marks secured in this Examination will be counted for deciding the final merit.

(v) The Preliminary Examination will be a Computer Based Examination.

(vi) The Main Examination will have three Papers for each Stream and all Papers will be of descriptive type. Marks secured in this Examination will be counted for deciding the final merit.

(vii) Existing General English Paper has been discontinued.

(viii) The Revised Scheme, Pattern and Syllabi of the Examination will be made effective from the 2020 Examination to give sufficient preparation time to the aspirants.

2. The details of this revised Pattern are attached.

Plan of Examination

1. The Examination shall be conducted according to the following plan:—

(i) Stage-I: Combined Geo-Scientist (Preliminary) Examination (Objective Type Papers) for the selection of candidates for the Stage-II: Combined Geo-Scientist (Main) Examination;

(ii) Stage-II: Combined Geo-Scientist (Main) Examination (Descriptive Type Papers) and

(iii) Stage-III: Personality Test

2. The detailed scheme of Combined Geo-Scientist Examination is as under:
