B7 (Biology) IDEAS IN CONTEXT June 2012

This is information that I expect will come up and we will need for the Ideas and Context in Biology B7 June 2012. I cannot guarantee that I have included all the information needed, or that the information listed below will be needed, but it will help with your general knowledge anyway. Good luck!

http://getrevising.co.uk/resources/b7_biology_ideas_in_context_potential_questions_and_answers  ------ HERE ARE THE POTENTIAL QUESTIONS (given by my teacher) AND POSSIBLE ANSWERS (written by myself). I can't guarantee the longer ones are 100% right, but they should give you a good idea of what they could ask, and what the answers may be! I hope they help! If you have any comments, queries (or you want to correct some of my answers), then comment below :). I have also added some links to useful websites, and added 6 extra questions I've found on the internet!

This document was written in a rush, and I wanted to put it up ASAP, so I apologise if some doesn't make sense, or if there are some spelling errors. You can also post a question if you don't understand, and hopefully I'll get back to you.

Producing new species:

Many new features within plants and animals have appeared over thousands of years, and
these changes have been caused by `new genes' which are the result of existing genes that
have changed. These have been caused by mutations, which are usually due to outside
factors, such as…

Humans and the Earth:

A lot of extinction is due to human activities, such as through deforestation, which causes many
organisms to lose their habitats. However, it can also be caused by humans indirectly- by indirectly
destroying an organism's habitat (e.g. the melting ice caps due to global warming and…
