Natural Science 301 Guidelines

This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.

    We have immune systems, do plants, fungi, and invertebrates have immune systems?

    What is the difference between monera bacteria and archea? They both are single celled organisms.

    Yes on plants and invertebrates; don't think so in the traditional sense on fungi, though they certainly produce a lot of toxins that kill other organisms. Plants and invertebrates both have innate immune systems, which recognize things that generally look like pathogens, rather than recognizing a specific pathogen. We have this plus the adaptive immune system, which is centered on antibodies and T-cell receptors.

    Monera is out of date, obviated by the discovery that bacteria and archaea are distinct. The distinctions involve things like the precise chemistry of the cell membranes, the presence or absence of specific protein complexes, and clustering on DNA analysis of similarity.

    To give some specific examples: if you did a phylogenetic tree of a well-conserved gene, bacteria and archaea would both cluster together, and be distinct from each other. Archaea have a simplified version of a protein-digesting complex called a proteasome (simplified relative to the eukaryotic version); bacteria lack this entirely.

      Can archea make you sick? Or are all pathogenic prokaryotes eubacteria type?

        As of 2013 (the most recent review i could find), there are no clear cases of disease causing archaea, although they will opportunistically inhabit some areas of the human body damaged by other diseases.

          Here's some more questions! How do eagles fly? How do snakes slither? And when did we figure out the answers to those questions? Because some guy named Agur didn't know and was amazed by it.

              I meant how their wings work! Agur probably knew they used wings. He just seemed to not know how it worked exactly.

              There are three things which are too wonderful for me,
              Four which I do not understand:
              19
              The way of an eagle in the sky,
              The way of a serpent on a rock,
              The way of a ship in the middle of the sea,
              And the way of a man with a maid.

                  I mean, it doesn't necessarily have to be read that way. I've always understood it to be something along the lines of migration paths/patterns, and not about the aerodynamics of wings.

                    Huh. So he could be referring to the eagles going somewhere and then coming back without getting lost? Who is Agur anyway? I just find it interesting that being intrigued about how something happens seems to be the reason we have science.

                      I decided to google around, and apparently "way" is somewhat of a unfortunate translation. Here's what ISBE (Note that it's from 1901, so it might not be the most up to date source) has to say on the passage:

                      Source: ISBE article on Eagle


                      "The way of an eagle in the air; The way of a serpent upon a rock: The way of a ship in the midst of the sea; And the way of a man with a maiden."

                      This reference to the eagle is to that wonderful power of flight that enables a bird to hang as if frozen in the sky, for long periods appearing to our sight immovable, or to sail and soar directly into the eye of the sun, seeming to rejoice in its strength of flight and to exult in the security and freedom of the upper air. The word "way" is here improperly translated. To the average mind it always means a road, a path. In this instance it should be translated:

                      The characteristics of an eagle in the air; The habit of a serpent upon the rock; The path of a ship in the midst of the sea; And the manner of a man with a maid. Each of these lines stood a separate marvel to Agur, and had no connection with the others (but compare The Wisdom of Solomon Song of Solomon 5:10,11, and see WAY).

                        In animals that generate significant lift forces (like true flyers), the angle of the wings against the flow of air creates a resistance that has the net effect of moving the wing (and the animal) upward. ... Thrust is a force induced in the direction of the animal's flight, opposing the drag force.

                        Some birds, like eagles, and some aircraft can also use soar on thermal air currents, and the aerodynamic nature of wings. Humans actually copied the aerodynamics of bird wings to design airplane wings.
