Biology Lab need done

his coming week, you will do your very last lab exercise – Lab 7. This particular lab deals with the Ecology of Organisms. In your BIOL 101 classes, you will by now have begun to discuss environmental issues. I have also introduced the topic this week – it is if utmost importance! Incidentally, you will also do a Final Analysis for this class, instead of a final Exam. I am urging you to do Option 2 for your final analysis. As we have already learned, physiological/chemical activities within any organisms may only properly happen between restricted ranges of temperature and pH levels. If they are wrong, cellular activities will slow down, or stop altogether. Organisms have adapted to a great variety of environmental conditions; but this means that they are limited to those areas. For example, many wildflowers of northern areas require that their seeds freeze for a while, before they can germinate. Such specializations are called ‘habitat tolerance’.

For Lab 7, you will grow radish seeds in regular water, a baking powder solution (alkaline) and a vinegar solution (acid) for seven days. All the materials are in your lab kit! You must keep a very careful record for 7 days. Therefore it is best to begin right away.

However, before you begin you exercise, please read the instructions carefully. Then set up your three petri dishes with the seeds, and extend your recording table to seven days. Then do your graph and answer the questions.
