  • Saxitoxin is a neurotoxin that is produced by some species of cyanobacteria and dinoflagellates. Saxitoxin causes paralytic shellfish poisoning in humans and can be a major threat to marine life. toxicity may be a side effect of the larger role it plays in the cyanobacterial cell.
  • Plasmodium, toxoplasma, and trypanosomes are some of the ~6000 apicomplexans comprising the most diverse lineage of parasites known. They are characterized by a miniaturized organelle, the apicoplast, which is a highly reduced plastid derived from an endosymbiosis with a red algae.
  • Transgenic organisms have been genetically engineered to express characteristics unique to their species. Cucurbita pepo is a species of squash that includes the zucchini, yellow squash and gourd. Not only is it common at the dinner table, it is a widely utilized transgenic plant – one that has passed its transplanted genes to wild populations.

I’ll be back next Friday with more selections.

    I have seen lots of useful factors on your site about computer systems. However, I’ve got the viewpoint that notebooks are still more or less not powerful adequately to be a option if you usually do jobs that require a lot of power, just like video touch-ups. But for web surfing, microsoft word processing, and quite a few other typical computer functions they are all right, provided you don’t mind the tiny screen size. Thank you for sharing your thinking.
