There are two articles on the myths of agricultural biotechnology (one from the popular press and one from the peer reviewed journal (the links are below):

article no. 1. http://www.vegsource.com/articles/gmo_feed_myth.htm

&

article no. 2. http://www.emater.tche.br/docs/agroeco/artigos/biotecologia.pdf

Help with answering a few questions on those articles is given:

a. What was the attention to details?

b. What triggered the research?

c. Who conducted the research?

d. What methods were used?

e. What conclusions were reached?

f. What does this tell you about Peer Reviewed Journal article and a Popular Press article?

Hi

These are certainly two interesting articles, with similar focus but some glaring differences in approach. I hope you managed to read through all of both of them and gain some understanding of the heady issue of biotechnology in agriculture. This is a topic that has recently been of utmost importance to many biologists, both those involved in biotech and those in conservation and environmental science.

In answer to your specific questions, I will try to give you some input about each one separately.

a) It struck me right away that Altieri's paper was far more detailed and logically structured than the news article. It also provided references for all of the information so that the reader can go to the original research and verify that it is valid, peer-reviewed, ...

Life on Earth - Biological Concepts from the Non-Science Major Perspective

Pine trees have a different way of getting through the winter. They have tough needles instead of leaves, and these needles can take freezing temperatures without being damaged. One trick they use is that the needles are covered with a layer of wax. This helps prevent freezing and water loss. They also contain natural anti-freeze chemicals that prevent them from freezing. The plants are able to continue photosynthesis just as long as they can get adequate water.

Based on a plants adaptations to environmental conditions there are a variety of paths that can be followed in the carbon fixation component of photosynthesis.

Plants have stomata in their leaves which can open and close based on environmental conditions. However, when stomata are closed, carbon dioxide cannot be collected.

The question: Are there any other adaptations that plants have made to adjust to environmental conditions?
