4.7 The future? In the USA, the automobile reached the 50 per cent household penetration rate in 1923, about 23 years into the industry's development. The PC reached that threshold rate in 1999, also about 23 years into its development. Given the discussion in Section 3, this suggests that the economy-wide effects of the PC have yet to be fully seen. And given the arguments in this section, it also suggests that the PC is now starting to reach the e

1.3.1 Inheritance of colour in maize
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.

Saltatory Conduction in Neurons
This 12 minute video is about saltatory conduction in neurons. Saltatory conduction works because of cytoplasm and the axon being electrically conductive. Because the cytoplasm and axon are electrically conductive, the myelin prevents electrical
charge to leak through the membrane. The video starts with a review and uses graphic cartoon images and a lecturer.
