Plain Tiger Butterfly--An Overview
This short video gives excellent real life, close up footage of Plain Tiger Butterflies. This beautifully bright butterfly has captivated humankind’s attention since it was first depicted in an Egyptian tomb 3,500 years ago, making it the first ever butterfly to be recorded in history. Its striking tawny-orange colouration serves as a warning to predators that this species is distasteful, which ultimately deters predators from attacking. This is a great resource to help build backgrou

8 Conclusions

In this course you have learned about the difference between the analogue world we inhabit and the digital world of the computer.

I've described how features of our world can ‘cross the boundary’ and be represented or modelled in the digital world, and then brought back across the boundary to us.

More excitingly, computer programs that manipulate digital representations of our world enable us to:

  • simulate physical and social processes;<

8.4 The organisation of the mitotic chromosome

In order to prepare the chromosome for mitosis, a process in which DNA molecules become physically separated, an additional stage of compaction occurs to reach the highest level. The processes involved in this final stage of compaction are not clearly understood, but can be represented diagrammatically as in Figure 43. The process probably involves the coiling together of scaffolds into the higher-order structure.

7.5 Summary of Section 7

  1. Site-directed mutagenesis is an important technique for studying protein function. Using recombinant DNA technology, selected amino acids can be substituted with different residues to alter the structure and function of a protein. One widely used method employs primer extension. SDM studies can help identify residues that are critical for interactions or catalytic activity.

  2. Protein–protein interactions can be studied in a number of different

1.1 Introduction

There are many environmental reasons why coal is a rather undesirable source of energy. Burning it introduces large amounts of gases into the atmosphere that harm the environment in a variety of ways, as well as other, solid waste products. Coal extraction leads to spoil heaps and mines that scar the landscape, land subsidence that affects roads and buildings, and in some cases water pollution.

With apparently so little going for it, why do we rely so much on coal to meet our energy nee

6.7 Modelling with objects
Enterprise systems are software applications that automate and integrate all many of the key business processes of an organisation. With some understanding of software development, you will learn about current development practices for this type of system and develop relevant skills to apply them to real-world problems. You will develop core skills in object-oriented analysis and design, allowing you to develop software that is fit for purpose, reusable and amenable to change.

2.1.2 Diffraction and interference of light

When light, or indeed any type of wave, passes through a narrow aperture, it will spread out on the other side. This is the phenomenon of diffraction. For example Figure 17 shows the diffraction of water waves in a device called a ripple tank. The extent to which waves are diffracted depends on the size of the aperture re
