Chapter Outlines Chapter 1: Origins Study Outline Use this outline to preview the chapter before you read a particular section in your textbook and then as a selfcheck to test your reading comprehension after you have read the chapter section. What is history and why do we study it? History is the effort to reconstruct the past. The past must be understood so we can understand the factors that shape us today. Historians reconstruct the past by posing questions about it and then attempting to answer them by studying primary and secondary sources. Herodotus, the "father of history," joined the two concepts of inquiry and research. Historians must assess the validity and perspective of each source they study.

Heritability Explained

A researcher seeking to quantify the influence of genes or environment on a trait needs to be able to separate the effects of one factor away from that of another. This kind of research often begins with attempts to calculate the heritability of a trait. Heritability quantifies the extent to which variation among individuals in a trait is due to variation in the genes those individuals carry. In animals where breeding and environments can be controlled experimentally, heritability can be determined relatively easily. Such experiments would be unethical for human research. This problem can be overcome by finding existing populations of humans that reflect the experimental setting the researcher wishes to create.

The history of algebra began in ancient Egypt and Babylon, where people learned to solve linear (ax = b) and quadratic (ax2 + bx = c) equations, as well as indeterminate equations such as x2 + y2 = z2, whereby several unknowns are involved. The ancient Babylonians solved arbitrary quadratic equations by essentially the same procedures taught today. They also could solve some indeterminate equations.

Page 1 / 249 PREFACE In the ACs? conference held in July, 2010 at KVS (HQ), New Delhi, issue of Study Material for Board classes was discussed at length and finally decided to provide it to students. Various Regional Offices were asked to prepare the study material in different subjects while the task of its correction and moderation was assigned to various ZIETs of KVS. KVS, ZIET, Chandigarh received study material in the subjects of Physics, Chemistry, and Biology &Maths for XII, Maths and Science &Tech. for X class, from various Regional Offices. The study material was got reviewed and suitably modified by organising workshops of experienced and competent subject
