In this course we will examine different perspectives on Russian history and literature in order to try to understand the Russian

2.10.1 Mean and standard deviation for repeated measurements
Observation, measurement and the recording of data are central activities in science. Speculation and the development of new theories are crucial as well, but ultimately the predictions resulting from those theories have to be tested against what actually happens and this can only be done by making further measurements. Whether measurements are made using simple instruments such as rulers and thermometers, or involve sophisticated devices such as electron microscopes or lasers, there are decisio

1.1.1 Chromosomes and the life cycle
This Unit looks at how units if inheritance are transmitted from one generation to the next. First you will look at what happens to the chromosones of animals and plants during the process of sexual reproduciton. Then you will examine how genes are transmitted in particular patterns from generation to generation. These two approaches combine to illustrate how the patterns of inheritance can be explained by the behaviour of chromosomes during sexual reproduction.
